The present invention relates to a solenoid valve fixing structure for fixing a solenoid valve to an intake manifold.
A system for reserving hydro-carbon gas using an activated carbon canister is well known; in which a hydro-carbon gas evaporated from the fuel in a fuel tank, due to engine heat or external heat, is temporally reserved in an activated carbon containing canister, and while the vehicle is running, the reserved gas is sent into the intake manifold of the engine of a vehicle so as to be burned out, for protecting the emission of the hydro-carbon gas into the atmosphere.
An apparatus for suppressing evaporated fuel gas emission, which uses such a system for reserving hydro-carbon gas in an activated carbon containing canister, has usually a solenoid valve for opening and closing channels for the evaporated fuel gas and/or the air. A solenoid valve fixing structure in the prior art, which is arranged between a canister and an intake manifold, is explained below.
FIG. 25 is a schematic diagram of an apparatus for suppressing the evaporated fuel gas emission in the prior art. FIG. 26 is a plan view of a part of a fixing plate disposed at an intake manifold. FIG. 27 is a partially cross-sectional view of a solenoid valve fixing structure according to the prior art.
Reference numeral 21 denotes a fuel tank, the fuel tank is connected with a separator 23 through a channel 22. The evaporated gas from the fuel tank is separated into a liquid component and a gas component by the separator 23. Reference numeral 24 denotes a pressure sensor for diagnosis, which detects pressure change of the evaporated fuel gas, for detecting leakage of the evaporated fuel gas while the vehicle is running. Reference numeral 25 denotes an activated carbon containing canister for reserving the evaporated fuel gas temporally. The canister 25 has an air introducing hole 26, an evaporated fuel gas introducing hole 27 and an outlet hole 28 of the reserved fuel gas, which is lead to an intake manifold 29 of the engine.
The purge quantity of the evaporated fuel gas from the canister 25 to the intake manifold 29 is controlled by a solenoid valve 30. As shown in FIGS. 26 and 27, the solenoid valve 30 is fixed to a fixing plate 31, which projects from the intake manifold 29. A bolt 34 fixes the solenoids valve 30 to a fixing hole 32 disposed in the fixing plate 31. An insert bush 33 is disposed between the fixing plate 31 and the bolt 34.
An air cut valve 35 controls the opening and closing of a channel communicating with the air introducing hole 26 of the canister 25. Ordinarily, the air cut valve 35 keeps an opening state so that the air introducing hole 26 is open to the atmosphere. This air cut valve 35 is closed, only when the communication from the atmosphere shall be cut off, at diagnosis of the apparatus is made. The air cut valve 35 is connected to the air introducing hole 26 through a hose 36.
The mounting of the solenoid valve onto the intake manifold 29 is carried out as follows: An insert bush 33 is previously set into the fixing plate 31 of the intake manifold 29; A bolt 34 is inserted into the solenoid valve 30; The bolt 34 is screwed into the insert bush 33.
Due to such a structure, the solenoid valve fixing structure of the prior art has following drawbacks. First, a bolt 34 must be screwed into the insert bush 33. Therefore the fixing is not easy and it takes a long time. Second, the solenoid valve 30 cannot be fixed compactly, because the solenoid valve is fixed onto a fixing plate 31, jutting from the manifold 29.
Of course, the fixing using a bolt 34 can be made easy, by changing the design of the external form of a solenoid valve 30. However the change of a design entails to a high fabrication cost.
A box-formed solenoid valve installed on a manifold is disclosed in JP-A-6-185654, as another prior art. The solenoid valve described in it also requires a change of designing of its external form. Thus it entails to a high fabrication cost, too.
SUMMARY OF THE INVENTION An object of the present invention is to eliminate these drawbacks of the prior art.
Another object is to propose a solenoid valve fixing structure, which is cheap in price and makes it possible to fix a solenoid valve to an intake manifold, without changing the external form of the existing solenoid valve.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Embodiment 1 The first embodiment of the present invention is explained below, referring to FIGS. 1-14.
At first, the structure of a solenoid valve fixing structure according to this embodiment is briefly explained.
In FIGS. 1, 9 and 10, reference numeral 1 denotes a solenoid valve, 2 is a bolt as a fixing means, 3 is a nut as a fixing means, 4 is a fixing member for fixing the solenoid valve 1 to a manifold, which is made form synthetic resin or metal (for example aluminum, iron). These elements are made from deformable synthetic resin (for example plastic resin) or deformable metal and are integrated to form one body. Reference numeral 6 denotes a recessing portion disposed in an intake manifold 5, and serves to receive a solenoid valve 1. The recessing portion can be formed by molding, when the intake manifold is made from synthetic resin.
The structure of the fixing member 4 is more precisely explained below.
Referring to FIGS. 2-4, a fixing part 4 a is a portion to be fixed with a solenoid valve 1, 4 b is a bolt hole for a bolt 2, 4 c is a through hole, 4 d is a pair of deformable lips elongated form the fixing member 4 a for defining the lateral position of the solenoid valve 1 in the recessing portion 6. The deformable lips 4 d are bent or folded so as to be deformable.
Reference numeral 4 e is an engaging hole, with which an engaging claw 6 b engages, which will be explained later. A pair of insertion lips 4 f elongates from the fixing part 4 a. The insertion lips 4 f are to be inserted between shoulder portions 6 d and 6 e, so as to define the vertical position of a solenoid valve 1 in the recessing portion 6. Reference numeral 4 g denotes a rounded portion for smooth insertion of the insertion lip 4 f into the space between the shoulder portions 6 d and 6 e. The structure of the recessing portion 6 is explained below. As shown in FIGS. 5-8, a pair of shoulders 6 a are arranged on the right and left wall of the recessing portion 6, which are designed so as to contact with the deformable lips 4 d. A pair of engaging claws 6 b projects from the right and left wall of the recessing portion 6. The claws 6 b are designed so as to engage with the engaging hole 4 e disposed in the deformable lips 4 d. A bolt clearance space 6 c is disposed in the recessing portion 6 at a position corresponding to the bolt 2 so as to make a clearance space between the bolt 2 and the recessing portion 6. A shoulder portion 6 d is disposed at a position over the bolt clearance space 6 c. The shoulder portion is designed so as to contact with the upper insertion lip 4 f. Another shoulder portion 6 e is disposed at a position under the bolt clearance space 6 c. The shoulder portion 6 c is designed so as to contact with the lower insertion lip 4 f. The function of the solenoid valve fixing structure of this embodiment is explained below: At first, a solenoid valve 1 shall be fixed to the fixing member 4, by mounting a bolt 2 to a solenoid valve 1; The bolt 2 is inserted through the bolt hole 4 b; And is tightened by a nut 3. The solenoid valve 1 is fixed following the steps as shown in FIGS. 11-13. Namely, the solenoid valve is inserted into the recessing portion 6, pinching by fingers the deformable lips 4 d, 4 d toward the solenoid valve. Then the deformable lips 4 d contacts with the shoulder 6 a and the insertion lips 4 f are received between the shoulders 6 d, 6 e, as shown in FIG. 9.
Releasing the deformable lips 4 d, 4 d from the fingers, as shown in FIG. 14, the deformable lips 4 d, 4 d opens to separate from the solenoid valve by its resilient force so that the engaging hole 4 e engages with the shoulder 6 a. As a result, the position of the solenoid valve 1 in the lateral direction is determined by this contact of the deformable lips 4 d and the shoulder 6 a. And, as shown in FIG. 9, the vertical position is determined by the contact of the insertion lips 4 f and the shoulders 6 d, 6 e. In this manner as explained, the solenoid valve 1 can be fixed in the recessing portion 6 strongly and promptly. In aforementioned embodiment, the deformable lips are pinched by fingers during the insertion of the solenoid valve. However, it is possible to designed a solenoid valve fixing structure, in which a solenoid valve is pushed in without pinching the deformable lips. In such a case, the deformable lips 4 d can be inserted into the recessing portion, by pushing in the solenoid valve, and profiting the elastic deformation of the deformable lips 4 d. When the solenoid valve 1 is fixed, the bolt 2 and the nut 3 are received in the bolt clearance space 6 c, and also the main body of the solenoid valve 1 is received in the recessing portion 6. This means that the solenoid valve can be fixed to a manifold compactly. The compactness of the fixing is improved remarkably compared with the prior art.
By the way, the solenoid valve 1 can be easily and promptly removed from the recessing portion 6 by pinching with fingers the deformable lips 4 d, 4 d towards the solenoid valve 1 and pulling it out.
As precisely explained above, this embodiment has an advantage that a solenoid valve 1 can be fixed easily and compactly to an intake manifold 5, by using a fixing member 4, which can be fabricated easily and cheaply, there is no need to redesign the external form of the solenoid valve 1, thus the total cost for fixing the solenoid valve is cheap.
The recessing portion 6 can have a larger vertical size which allows to receive a larger sized solenoid valve. In such a case, when a larger sized solenoid valve would be required to be installed in the future, such a solenoid valve 1 could be easily installed and fixed accordingly. FIG. 15 shows a lateral cross sectional view of the recessing portion, when such a larger sized solenoid valve is installed therein.
A solenoid valve fixing structure according to the first embodiment is explained, on the basis of the forms of the fixing member 4 and the recessing portion 6 as shown in the figures. However a solenoid valve fixing structure comprising a fixing member and a recessing portion, which have similar effects as aforementioned embodiment, belongs to the scope of the present invention.
Embodiment 2 FIG. 16 shows a plan view of a solenoid valve fixing structure according to the second embodiment of the present invention, FIG. 17 is a B�B cross-sectional view of FIG. 16. In the following explanation, elements already explained in the first embodiment are referred by the same reference numeral as in the explanation of the first embodiment. And their explanation is not repeated.
In FIGS. 16, 17, reference numeral 7 denotes a fixing member, which is made from metal or synthetic resin, ,to be fixed to a solenoid valve 1. The fixing member 7 comprises a fixing part 7 a, which has a substantially U form cross section. The fixing part 7 a is a portion to be fixed to a solenoid valve. The fixing member further comprises an insertion lip 7 b, which elongates from the fixing part 7 a and to be held between a recessing portion 8 and a holding lip 8 b, which are explained later. An engaging claw 7 c juts from the insertion lip 7 b. The fixing part 7 a, the insertion lip 7 b and the engaging claw 7 c are integrated to form a fixing member 7.
Reference numeral 8 denotes a recessing portion disposed in an intake manifold 5. A shoulder portion 8 a is disposed in the recessing portion 8 so as to engage with the engaging claw 7 c. A pair of holding lips 8 b is disposed over the recessing portion. The holding lips 8 b and the recessing portion 8 hold the insertion lip 7 b between them. The fixing part 7 a and the solenoid valve 1 are fixed to each other by means of, for example, welding, screwing, or press fitting, etc.
The function of the solenoid valve fixing structure of the second embodiment is explained below.
The insertion lips 7 b of the fixing member 7, which is fixed to a solenoid valve 1, are pushed in so as to slide between the recessing portion 8 and the holding lips 8 b, until the engaging claw 7 c engages with the shoulder portion 8 a. In this manner, the fixing of a solenoid valve 1 to a intake manifold can be promptly completed.
As explained above, this embodiment has an advantage that a solenoid valve 1 can be fixed easily and compactly to an intake manifold 5, by using a fixing member 7, which can be fabricated easily and cheaply. There is no need to redesign the form of the solenoid valve 1, thus cost for the fixing of the solenoid valve is cheap.
Embodiment 3 FIG. 18 shows a plan view of a solenoid valve fixing structure according to the third embodiment of the present invention. FIG. 19 shows a C�C cross-sectional view of FIG. 18.
In FIGS. 18 and 19, reference numeral 9 denotes a fixing member to be fixed to a solenoid valve 1. The fixing member 9 is made from metal or synthetic resin. The fixing member 9 comprises a fixing part 9 a having a substantially U-formed cross section, an insertion lip 9 b, which is an elongated portion of the fixing part 9 a, and an engaging claw 9 c jutting from the insertion lip 9 b. The fixing portion 9 a is a portion to be fixed to a solenoid valve 1. The insertion lip 9 b has a substantially L-formed cross section so as to be held between a recessing portion 10 and a holding lip 10 b, which are explained below. The fixing lip 9 a, insertion lip 9 b and engaging claw 9 c are integrated to form a fixing member 9.
Reference numeral 10 denotes a recessing portion disposed on an intake manifold 5. Reference numeral 10 a denotes a shoulder portion, which can engage with the engaging claw 9 c. A holding lip 10 b is disposed on the manifold 5 so that the insertion lip 9 b can be held between the holding lip 10 b and the recessing portion 10. A groove 10 c guides the tip portion of the insertion lip 9 b. The fixing part 9 a and the solenoid valve 1 can be fixed to each other by welding, screwing, or press fitting, etc.
The function of the solenoid valve fixing structure according to the third embodiment is explained below.
After fixing a solenoid valve 1 to the fixing member, the insertion lips 9 b of the fixing member 9 is pushed in so as to slide between the recessing portion 10 and the holding lips 10 b, until the engaging claw 9 c engages with the shoulder 10 a. Then the fixing of a solenoid valve 1 to a intake manifold completes promptly. The insertion lip 9 b is guided also by the groove 10 c. Thus the position of the insertion lip 9 b is defined by the groove 10 c. Therefore the fixing of the solenoid valve is stable.
As explained, this embodiment has an advantage that a solenoid valve 1 can be fixed easily and compactly to an intake manifold 5, by using a fixing member 9, which can be fabricated easily and cheaply. There is no need to redesign the form of the solenoid valve 1, thus cost for the fixing of the solenoid valve is cheap.
Embodiment 4 The fourth embodiment is explained below, referring to FIGS. 20-24.
In this embodiment, the structure of the solenoid valve side is similar to that in the first embodiment, on the other hand, the intake manifold side is modified from that in the first embodiment. Therefore the explanation about the solenoid valve side is omitted here.
Four receiving elements 11 a, 11 b, 12 a, 12 b are projecting from an intake manifold. The receiving lips 11 a, 11 b receive the pair of deformable lips 4 d, 4 d. The receiving lips 12 a, 12 b receive the pair of deformable lips 4 f, 4 f. The receiving elements 11 a, 11 b have a shoulder portion 6 d, 6 d which can engage with the insertion lip 4 f, 4 f. The receiving lips 12 a, 12 b have an engaging claw 6 b, 6 b, which juts so as to engage with the engaging hole 4 e, 4 e disposed in the deformable lip 4 d, 4 d. When the intake manifold is made by molding of synthetic resin, this structure facilitates the molding. But the compactness of the solenoid valve fixing deteriorates compared with the first embodiment, because the solenoid valve juts from the intake manifold.
In the first embodiment, in order to facilitate the piping work or wiring work, the inlet, the outlet and the connector from the solenoid valve are orientated in the longitudinal direction of the recessing portion. On the other hand, in this embodiment, it can be orientated lateral to the longitudinal direction of the recessing portion. Thus, connections with other piping and wiring are easy in this embodiment.
An advantage of the solenoid valve fixing structure according to the present invention is, as explained, that a solenoid valve can be fixed easily and compactly to an intake manifold, because the structure comprises a recessing portion and a fixing member having a fixing lip, a deformable lip and an insertion lip. There is no need to redesign the external form of the solenoid valve.,
Another advantage of the present invention is that a solenoid valve can be fixed promptly and strongly, by disposing a shoulder portion for defining the insertion position and the insertion lip into the recessing portion and another shoulder period for defining the contacting position of the deformable lip.
Another advantage of the present invention is that the solenoid valve can be surely fixed, because an engaging hold is disposed in the deformable lip, and an engaging claw is disposed in the recessing portion so that the deformable lip can engage with the engaging claw.
An advantage of the present invention is that a compact fixing of a solenoid valve can be attained, by disposing a bolt clearance space in the recessing portion, so that a fixing means for fixing the fixing part to a solenoid valve can be received therein.
Another advantage of the present invention is that a solenoid valve can be fixed easily and cheaply, by using a recessing portion having a shoulder portion, a holding lip and a fixing member having a fixing part, an insertion lip and an engaging lip. There is no need to redesign to change the external form of an existing solenoid valve.
