Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a valve sealing device for a tilting-armature valve, to a method for producing a valve sealing device for a tilting-armature valve and to a use of a valve sealing device in a tilting-armature valve for a pressure regulating module of a vehicle. 
       BACKGROUND INFORMATION 
       [0002]    Valves have seals in order to close off a valve outlet or a valve inlet in a fluid-tight fashion. 
       SUMMARY OF THE INVENTION 
       [0003]    Against this background, an improved valve sealing device for a tilting-armature valve, a method for producing a valve sealing device for a tilting-armature valve and a use of a valve sealing device a tilting-armature valve for a pressure regulating module of a vehicle as described herein is disclosed. Advantageous refinements can be found in the respective further descriptions herein and the following description. 
         [0004]    A sealing device for a valve, in particular a tilting-armature valve, can be arranged on a movable element of the valve such as, for example, a tilting armature. The sealing device is positioned fixedly and the sealing device is coupled to the movable element by a retaining body of the valve sealing device. The functionality of the sealing is performed by a sealing body or a surface of the sealing body when the sealing body is moved against a valve seat or pressed against said valve seat. 
         [0005]    A valve sealing device for a tilting-armature valve comprises: 
         [0006]    a sealing body, a first surface of which is designed to close in a fluid-tight fashion a valve seat and/or an opening in a valve; and 
         [0007]    a retaining body which is arranged on the surface of the sealing body which is opposite the first surface, and is designed to secure the valve sealing device in and/or on a cutout in a valve, in particular in a cutout in a tilting armature of a tilting-armature valve, in particular wherein the sealing body and/or the retaining body are/is essentially cylindrical in shape. 
         [0008]    A valve sealing device can be understood to be a sealing element and/or a damper element for a valve. A sealing body can be a plastic-elastic solid body. The first surface of the sealing body can be formed in a planar fashion. The sealing body can merge with the retaining body on the surface or side which is opposite the first surface. An external contour of the sealing body can differ from an external contour of the retaining body here. 
         [0009]    The sealing body can be at least partially surrounded by a metal sleeve, in particular a metal pot. Additionally or alternatively, the retaining body can be at least partially surrounded by a metal sleeve, in particular a metal pot. The metal sleeve can be a deep-drawn pot. The valve sealing device can be surrounded by a sheet-metal deep-drawn part or a sheet-metal covering, wherein only the end-side supporting face or sealing face, that is to say the first surface, is free of the sheet-metal covering. Therefore, more efficient and therefore more cost-effective fabrication can be achieved by multiple vulcanization. At the same time, the valve sealing device, in particular the sealing body, can have a stable side wall, as a result of which better dimensional stability of the sealing body which acts as a sealing element and damper element can be achieved in the case of frequent valve activation. 
         [0010]    The valve sealing device can have a further sealing body which is arranged on a side of the retaining body which is opposite the sealing body. In particular, the further sealing body can be surrounded at least partially by a further metal sleeve. A shape or an external contour of the sealing body and a shape or an external contour of the further sealing body can correspond to one another. The further metal sleeve can have the same shape as the metal sleeve. 
         [0011]    The sealing body and the further sealing body can each have an essentially round base shape. The sealing body and the further sealing body can be arranged offset with respect to one another. 
         [0012]    In this context, the sealing body and the further sealing body can be connected via the retaining body located between them. 
         [0013]    It is also favorable if the sealing body and the further sealing body are each at least partially surrounded by a metal sleeve, in particular a metal pot. In this context, at least one armature which is connected to the metal sleeve which surrounds the sealing body and at least one armature which is connected to the further metal sleeve which surrounds the further sealing body can be enclosed by the retaining body. The armature which is connected to the metal sleeve and the armature which is connected to the further metal sleeve can each have two limbs which are aligned transversely with one another. In this way, the armature can be formed in an L shape. In this context, a relatively long limb of the armature can be connected to the metal sleeve. If the metal sleeve is formed as a metal pot, the armature can be connected to a floor of the metal pot. In this context, the floor can have a hole wherein on one side of the hole the armature is connected to the floor of the metal pot. A multiplicity of armatures can be embodied on a metal sleeve. In this context, the retaining body can have an elongate shape. 
         [0014]    The elastomer of the sealing body and/or of the further sealing body is advantageously surrounded by a sheet-metal outer wall in such a way that the supporting face or sealing face which has been referred to as the first surface or further first surface is free of sheet-metal covering, while at least the side walls are encapsulated by sheet metal, in order to ensure that the sealing body and/or the further sealing body have good dimensional stability of the sealing body and/or of the further sealing body despite frequent valve activation. The sealing body and the further sealing body can also be referred to as a sealing element and a damper element to their function in a tilting-armature valve. 
         [0015]    A method for manufacturing a valve sealing device for a tilting-armature valve has at least one forming step of a sealing body and a retaining body. In this context, a first surface of the sealing body is designed to close in a fluid-tight fashion a valve seat and/or an opening in a valve. In this context, the retaining body is arranged on the surface of the sealing body which is opposite the first surface. The retaining body is designed to secure the valve sealing device in and additionally or alternatively on a cutout in a valve, in particular in a cutout in a tilting armature of a tilting-armature valve, in particular wherein the sealing body and/or the retaining body are/is essentially cylindrical in shape. 
         [0016]    In the forming step, the sealing body and additionally or alternatively the retaining body can be vulcanized. In this context, the valve sealing device can be formed or vulcanized in one piece. 
         [0017]    The method can additionally comprise at least one of the following steps: 
         [0018]    making available a first sheet-metal panel and second sheet-metal panel; 
         [0019]    deep drawing a first metal sleeve, in particular a first metal pot, and at least a second metal sleeve, in particular a second metal pot, in the first sheet-metal panel and a first metal sleeve, in particular a first metal pot, and at least a second metal sleeve, in particular at least a second metal pot, in the second sheet-metal panel; 
         [0020]    punching a first ring, interrupted by at least one retaining bridge, around the first metal sleeve and a second ring, interrupted by at least one retaining bridge, and the at least second metal sleeve, in each of the two sheet-metal panels; 
         [0021]    aligning the first sheet-metal panel with the second sheet-metal panel, wherein the metal sleeves which are deep-drawn in the deep drawing step point toward one another; and/or 
         [0022]    singularizing the first valve sealing device and/or the at least second valve sealing device by breaking the retaining bridges. 
         [0023]    In the forming step a first sealing body can be formed within the first metal sleeve of the first sheet-metal panel and a further first sealing body can be formed within the first metal sleeve of the second sheet-metal panel, and a first retaining body can be formed between the first metal sleeve of the first sheet-metal panel and the first metal sleeve of the second sheet-metal panel, wherein the first retaining body connects the first sealing body to the further first sealing body. In this context, the first sealing body, the first retaining body and the further first sealing body can form a first valve sealing device. In the forming step an at least second sealing body can be formed within the at least second metal sleeve of the first sheet-metal panel and an at least further second sealing body can be formed within the at least second metal sleeve of the second sheet-metal panel, and an at least second retaining body can be formed between the at least second metal sleeve of the first sheet-metal panel and the at least further second metal sleeve of the second sheet-metal panel, wherein the at least second retaining body connects the at least second sealing body to the at least further second sealing body. In this context, the at least second sealing body, the at least second retaining body and the at least further second sealing body can form at least a second valve sealing device. 
         [0024]    One variant of a valve sealing device described here is used in a tilting-armature valve for a pressure regulating module on a vehicle, wherein the tilting-armature valve comprises at least one coil element, an armature, a spring and a half-shell, wherein the coil element comprises at least one coil former and a coil which is arranged radially around the coil former, wherein the armature is mounted on an end side of the armature by a bearing, wherein the armature can be moved from a first position into a second position by activating the coil, wherein the spring is designed to move the armature, wherein a first partial region of the spring is arranged on a side of the armature facing the coil element and applies a force to the armature in order to move the armature in the direction of the first position, and a second partial region of the spring is arranged on a side of the armature facing away from the coil element, wherein the valve sealing device is arranged on the side of the armature facing away from the coil element, and wherein a valve seat with an outlet and an inlet for a fluid are formed in the half-shell, wherein in the first position of the armature the outlet can be closed off in a fluid-tight fashion by the valve sealing device.

     DETAILED DESCRIPTION 
       [0040]    In the following description of the exemplary embodiments of the present invention, identical or similar reference numbers are used for the elements which are illustrated in the various drawings and act similarly, with a repeated description of these elements being omitted. 
         [0041]      FIG. 1  shows a schematic illustration of two valve sealing devices  100  in a tilting armature  102  according to an exemplary embodiment of the present invention. A valve sealing device  100  is respectively arranged at two opposite sides in the tilting armature  102 . The valve sealing devices  100  have in each case a sealing body  104  and a retaining body  106 . A first surface  108  of the valve sealing device  100  is designed to close in a fluid-tight fashion a valve seat and/or an opening in a valve. The retaining body  106  is arranged on the surface  110  of the sealing body  104  which is opposite the first surface  108 . The retaining body  106  is designed to secure the valve sealing device  100  in or on a cutout of the tilting armature  102 . For this purpose, the tilting armature  102  has two cutouts, in each of which a retaining body  106  of the two valve sealing devices  100  is arranged. 
         [0042]    Both the sealing body  104  and the retaining body  106  are surrounded by a metal sleeve  112 . In the exemplary embodiment shown in  FIG. 1 , the metal sleeve  112  is embodied as a deep-drawn metal pot  112 . For example, the metal pots  112  are filled with vulcanized rubber in the exemplary embodiment illustrated in  FIG. 1 . 
         [0043]    The tilting armature  102  is designed to be used in a tilting-armature valve as illustrated in  FIG. 14 . The two metal pots  112  which are filled with vulcanized rubber are pressed individually into the armature plate  102 . In this context, two identical metal pots  112  can be used for a valve seat and for a damper in the tilting-armature valve. The method described in  FIG. 13  for producing the valve sealing devices  100  shows how a large number of metal pots  112  on a common sheet-metal panel are simultaneously vulcanized in a cost-effective fashion, in comparison with or instead of vulcanizing individual and comparatively large armature sheet-metal elements  102 . Corresponding sheet-metal panels are described in  FIG. 4  and  FIG. 12 . 
         [0044]    In the exemplary embodiment illustrated in  FIG. 1 , both the sealing body  104  and the retaining body  106  are essentially cylindrical in shape.  FIG. 2  shows the specified cutout in the tilting armature  102 , which cutout has at least one pitch line which is designed to prevent rotation of the valve sealing device. In this context, the valve sealing device  100  is pressed into the cutout. 
         [0045]      FIG. 2  shows a simplified illustration of a detail of a tilting armature  102  according to an exemplary embodiment of the present invention. The tilting armature  102  is designed to be used as a movable valve element in a tilting-armature valve. The tilting armature  102  can be an exemplary embodiment of a tilting armature  102  shown in  FIG. 1 . The tilting armature  102  shown in  FIG. 2  has an essentially rectangular shape, wherein the illustration is cut away on the right-hand side. Two cutouts  214  which are arranged directly one next to the other along the longitudinal extent of the tilting armature  102  with a thin web between the two cutouts  214  are formed in the tilting armature  102 . The cutouts  214  each have two partial regions with a partially straight line  216  parallel to the longitudinal extent of the tilting armature  102 . The two partially straight lines  216  of a cutout  214  are therefore arranged on two opposite sides of the cutout  214 . The partially straight lines  216  are designed to prevent rotation of a valve sealing device which is pressed into the cutout. The valve sealing devices which can be pressed into the cutout  214  can be exemplary embodiments of the valve sealing device  100  which is shown in  FIG. 1 . 
         [0046]    In one exemplary embodiment, the cutout  214  is, as shown in  FIG. 2 , embodied as a breakthrough or hole, and in another exemplary embodiment the cutout  214  is embodied, as shown in  FIG. 1 , as a drilled hole or depression into which the valve sealing device can be inserted. 
         [0047]      FIG. 3  shows a schematic illustration of a valve sealing device  100  according to an exemplary embodiment of the present invention. The valve sealing device  100  can be a variant of an exemplary embodiment (shown in  FIG. 1 ) of a valve sealing device  100 . The valve sealing device  100  comprises a sealing body  104  and a retaining body  106 . The layer which forms the sealing body  104  and the layer which forms the retaining body  106  are arranged bearing one directly on the other. The valve sealing device  100  also comprises a metal sleeve  112  which completely encapsulates the valve sealing device as far as the first surface  108 . In this context, the metal sleeve  112  can, as illustrated in the following fig clock  FIG. 4 , be composed of a piece of sheet metal, in that the metal sleeve  112  is produced as a deep-drawn element. The metal sleeve  112  is filled with a permanently elastic material which, when subjected to mechanical stress, returns to its original position and has a high tearing strength. 
         [0048]      FIG. 4  shows a schematic illustration in a plan view of a sheet-metal panel  420  for producing a multiplicity of valve sealing devices according to an exemplary embodiment of the present invention. The valve sealing devices can be exemplary embodiments of the valve sealing devices  100  which are shown in  FIG. 1  or  FIG. 3 . The sheet-metal panel  420  has a rectangular shape. In each case eight metal pots  112  for corresponding valve sealing devices are arranged in five rows in the sheet-metal panel  420 . 
         [0049]    The metal pots  112  are deep-drawn metal pots  112  which have a step in their side wall, that is to say a further section which is deep-drawn even further in a first floor of the metal pot  112 . The metal pots  112  are each secured in the sheet-metal panel  420  by four retaining bridges  422 . In this context, the retaining bridges  422  are formed in such a way that the metal pots  112  can be easily separated. The metal pots  112  are correspondingly also referred to as deep-drawn pots  112  in accordance with their method of production. 
         [0050]    In order to ensure clarity, both in the case of the retaining bridges  422  and in the case of the centering holes  424  described below just one retaining bridge  422  or centering hole  424  is respectively provided with a reference number. 
         [0051]    The sheet-metal panel  420  has, at the four corners, in each case two centering holes  424  for precisely inserting the sheet-metal panel  420  into an injection molding mold. The two centering holes are arranged one next to the other, in each case in the main directional extent of the sheet-metal panel  420 . 
         [0052]      FIG. 4  also shows a sectional axis B which runs centrally through the first row of metal pots  112 . A corresponding sectional view is illustrated as a side view in  FIG. 5 . 
         [0053]      FIG. 5  shows a schematic sectional illustration of a sheet-metal panel  420  for producing a multiplicity of valve sealing devices  100  according to an exemplary embodiment of the present invention. The valve sealing devices  100  can be exemplary embodiments of valve sealing devices  100  shown in  FIG. 1  or  FIG. 3 . The sheet-metal panel  420  can be an exemplary embodiment of a sheet-metal panel  420  shown in  FIG. 4 , wherein the illustration in  FIG. 5  shows a sectional illustration along the sectional axis B of the sheet-metal panel  420  shown in  FIG. 4 . Eight valve sealing devices  100  are illustrated in the sectional view. In the sectional illustration, the sheet-metal panel  420  has, in a row, eight metal pots  112  which can be separated and in each of which a sealing body  104  and a retaining body  106  is vulcanized. The valve sealing devices  100  are therefore vulcanized completed components before separation. 
         [0054]      FIG. 6  shows a schematic sectional view of a valve sealing device  100  according to a further exemplary embodiment of the present invention. The valve sealing device  100  can be an exemplary embodiment of a valve sealing device  100  shown in  FIG. 1 ,  FIG. 3  or  FIG. 5 . The valve sealing device  100  shown in  FIG. 6  has a further sealing body  604  which is arranged on a side of the retaining body  106  which is opposite the sealing body  104 . Both the sealing body  104  and the further sealing body  604  are at least partially surrounded by a metal sleeve  112 ,  612 . Both the metal sleeve  112  and the further metal sleeve  612  are embodied as metal pots  112  or further metal pots  612  which, with the exception of the first surface  108  and a further first surface  608 , encapsulate the sealing body  104  or the further sealing body  604 , respectively. The sealing body  104  and the further sealing body  604  are connected to one another via the retaining body  106 . In this context, the first surface  108  of the sealing body  104  and the further first surface  608  of the further sealing body  604  point in two opposite directions. As is apparent from the following figure,  FIG. 7 , the sealing body  104  and the further sealing body  604  each have an essentially round base shape. 
         [0055]    In a floor of the metal pot  112  which encapsulates the sealing body  104  two so-called armatures  630  are punched free. One end of the two armatures  630  is respectively connected to the metal pot  112 . In this context, the armature  630  has a L shape, as is apparent, in particular, in  FIG. 7 . One limb of the L shape is therefore connected to a floor of the metal pot  112 . This also applies analogously to the further metal pot  612 . 
         [0056]    The sealing body  104  and the further sealing body  604  are arranged offset with respect to one another. In this context, the sealing body  104  and the further sealing body  604  are oriented with respect to one another in such a way that in each case an armature  630  engages in itself, or two corresponding armatures  630  engage one in the other. The armatures  630  are enclosed by the retaining body  106 . 
         [0057]    The exemplary embodiment of a valve sealing device  100  which is illustrated in  FIG. 6  is illustrated in the following figures  FIG. 7  to  FIG. 10  in various views and installation positions in a tilting armature. 
         [0058]      FIG. 7  shows a schematic illustration in a plan view of a valve sealing device  100  according to an exemplary embodiment of the present invention. The valve sealing device  100  can be an exemplary embodiment of a valve sealing device  100  which is shown in  FIG. 6 . The sealing body  104  and the further sealing body  604  are arranged offset with respect to one another, wherein one partial region of the sealing body  104  overlaps with one partial region of the further sealing body  604 . The sealing body  104  and the further sealing body  604  are connected to one another via the retaining body  106 . The sealing body  104  is at least partially encapsulated by a metal sleeve  112 . The metal sleeve  112  is connected to an armature  630 , wherein the armature  630  projects into the retaining body  106 . The further sealing body  604  is at least partially encapsulated by a further metal sleeve  612 . The further metal sleeve  612  is connected to an armature  630 , wherein the armature  630  projects into the retaining body  106 . 
         [0059]    The retaining body  106  has a base shape in the form of a parallelepiped, the two sides of which are each fitted to the rounding of the sealing body  104  or of the further sealing body  604 . The two side faces of the retaining body  106  which can be seen in the plan view have, in a central region, a projection which is designed to secure the valve sealing device  100  in a correspondingly formed tilting armature. 
         [0060]    In the exemplary embodiment illustrated in  FIG. 7 , the retaining body  106  can also be referred to as a bridge  106  between the sealing body  104  and the further sealing body  604 . Both the sealing body  104 , the further sealing body  604  and the retaining body  104  can be fabricated essentially from a permanently elastic material such as, for example, rubber or a rubber-like mixture or mixture of plastics. The sealing body  104  can be used, for example, as a damper rubber in a tilting-armature valve. The further sealing body  604  can be used, for example, as a valve rubber in a tilting-armature valve. A corresponding tilting armature is illustrated in  FIG. 9 . A corresponding tilting-armature valve is illustrated in  FIG. 14 . 
         [0061]    In  FIG. 7  two arrows are illustrated which represent a view A and a view B. One view from the direction denoted by A is illustrated in  FIG. 10 , and one view from the direction denoted by B is illustrated in  FIG. 8 . 
         [0062]      FIG. 8  shows a schematic sectional view of a valve sealing device  100  arranged in a tilting armature  102  according to an exemplary embodiment of the present invention. The illustration of the valve sealing device  100  corresponds to the illustration in  FIG. 6 , with the difference that the valve sealing device  100  is arranged in a tilting armature  102 . The sealing body  104  is arranged on one side of the tilting armature  102 , and the further sealing body  604  is arranged on a side of the tilting armature  102  which is opposite the arrangement of the sealing body  104 . A thickness of the tilting armature  102  corresponds to a distance between the sealing body  104  and the further sealing body  604  which is filled by the retaining body  106 . The metal sleeves  112 ,  612  of the two sealing bodies  104 ,  604  are arranged essentially on the surface of the tilting armature  102 . 
         [0063]    The illustration in  FIG. 8  corresponds to the valve sealing device  100  illustrated in  FIG. 7  in a side view from the direction indicated by the arrow B. 
         [0064]      FIG. 9  shows a schematic illustration of a tilting armature  102  with a valve sealing device  100  which is arranged thereon, according to an exemplary embodiment of the present invention. The valve sealing device  100  can be the exemplary embodiment shown in  FIG. 8 , as in the case of the tilting armature  102 .

Rubber is vulcanized as damper rubber or valve rubber for a tilting-armature valve into the metal pots  112 ,  612 . Formulated in more general terms, this means that the valve sealing device  100  comprises two sealing bodies  104 ,  604  which are connected via a retaining body  106 . In this context, the sealing bodies  104 ,  604  are surrounded by a metal pot  112 ,  612 . Armatures  630  connect the metal pots to the retaining body  106 , with the result that a compact and ultimately single-piece component is produced. 
         [0068]    In the illustration of  FIG. 11 , a side view with six valve sealing devices  100  is illustrated in a sectional illustration on the right. A plan view of a valve sealing device  100  is illustrated on the left. In this context, the plan view corresponds largely to the illustration in  FIG. 7 , with the illustration in  FIG. 11  being somewhat further simplified. 
         [0069]    The valve sealing device  100  is also referred to as a vulcanized sealing pill unit. As is apparent in  FIG. 9 , the valve sealing devices  100  are designed to be laterally lowered into a tilting armature. 
         [0070]      FIG. 12  shows a schematic illustration in a plan view of a sheet-metal panel  420  for producing a multiplicity of valve sealing devices according to an exemplary embodiment of the present invention. The valve sealing devices can be exemplary embodiments of the valve sealing devices  100  shown in  FIG. 6  to  FIG. 11 . The sheet-metal panel  420  is rectangular in shape. In each case eight metal pots  112  for corresponding valve sealing devices are arranged in four rows in the sheet-metal panel  420 . The metal pots  112  are deep-drawn metal pots  112 . In each case two armatures  630  are punched from or formed in the metal pots  112 . The metal pots  112  are each secured in the sheet-metal panel  420  by four retaining bridges  422 . In this context, the retaining bridges  422  are formed in such a way that the metal pots  112  can be separated easily. The metal pots  112  are also referred to as deep-drawn pots  112  in accordance with their method of production. 
         [0071]    At the four corners, the sheet-metal panel  420  has in each case two centering holes  424  for precisely inserting the sheet-metal panel  420  into an injection molding mold. The two centering holes are each arranged one next to the other in the main direction of extent of the sheet-metal panel  420 . 
         [0072]    In order to preserve clarity, both in the case of the metal pots  112 ,  612 , the armatures  630 , the retaining bridges  422  and in the case of the centering holes  424 , in each case only one metal pot  112 ,  612 , one armature  630 , one retaining bridge  422  or one centering hole  424  has been respectively provided with a reference number. 
         [0073]    The position of further metal pots  612  which are formed in a further sheet-metal panel  420  is illustrated by dashes, wherein the further sheet-metal panel  420  is placed upside down under the first sheet-metal panel. The two sheet-metal panels  420  are formed in the same way. 
         [0074]      FIG. 12  also shows a sectional axis B which runs centrally through the first row of the metal pots  112 . A corresponding sectional image is illustrated as a sectional view in  FIG. 5 . 
         [0075]      FIG. 13  shows a flowchart of a method  1300  for the production of a valve sealing device for a tilting-armature valve according to an exemplary embodiment of the present invention. The valve sealing device can be a valve sealing device  100  as described in the preceding figures. The method  1300  has at least one forming step  1350 , wherein in the forming step  1350  a sealing body is formed, a first surface of which is designed to close in a fluid-tight fashion a valve seat and/or an opening in a valve. Furthermore, in step  1350  a retaining body is formed which is arranged on the surface of the sealing body which is opposite the first surface, and said retaining body is designed to secure the valve sealing device in and/or on a cutout in a valve, in particular in a cutout in a tilting armature of a tilting-armature valve, in particular wherein the sealing body and/or the retaining body are/is essentially cylindrical in shape. 
         [0076]    In the forming step  1350 , the sealing body and/or the retaining body are optionally vulcanized. 
         [0077]    In optional exemplary embodiments, the method  1300  has further optional steps. In this context, all of the steps which are optionally specified here are not absolutely necessary but rather the method  1300  can be extended, for example, with one of the following steps.
