The present invention relates to a jet regulator (1) having a jet fractionating device inside a mounting housing (6). The jet regulator (1) according to the present invention is characterized in that the mounting housing (6) is divided into at least two housing parts (7, 8), and that the housing parts (7, 8) can be connected to one another, and that a housing part (7) at the flow inlet side is connected fixedly and non-releasably with the jet fractionating device (2). The jet regulator (1) according to the present invention is distinguished by a high degree of shape stability and by manufacturing costs that are nonetheless low, even for small housing diameters (see FIG. 1).
33. Jet regulator (1), having a flow inlet side and a flow outlet side and comprising a mounting housing (6), divided into first and second housing parts (7, 8), which are releasably connectable via a snap-fit connection with one another, a jet fractionating device (2), having through flow holes (3), located inside the mounting housing (6), the first housing part (7), having a peripheral shoulder at the flow inlet side, is connected fixedly and non-detachably with the jet fractionating device (2), a flow rectifier (14), having flow guide walls defining exit openings arranged in a plane, are arranged, downstream from the jet fractionating device (2), at the flow outlet side.
The present invention relates to a jet regulator having a mounting case that is divided into at least two case parts that can be connected to one another. A jet regulator of the above-noted type is known for example from DE 30 00 799 A1. The known jet regulator, which can for example be built into the outflow mouth of a sanitary outflow armature, has in the interior of its mounting housing a jet fractionating device, formed as a perforated plate, that divides the inflowing jet of water into a multiple of individual jets. In a jet regulating device, these individual jets are formed (after an admixture of air if necessary) into a homogenous, soft-beading, non-spraying water jet.
FIG. 1 shows a sanitary fitting, constructed as a jet regulator, in a longitudinal section, comprising a jet fractionating device at the flow inlet side, to which a jet regulating device is connected downstream in the direction of flow that has a plurality of insert parts situated at a distance from one another, and a flow rectifier forms the end of this jet regulator at the flow outlet side,
FIG. 1 shows a sanitary fitting that can be placed into the outflow mouth of a sanitary outflow armature. The insert part is here formed as jet regulator 1, which is used to produce a homogenous, soft-beading, non-spraying jet of water. For this purpose, jet regulator 1 has a jet fractionating device 2 that is fashioned as a perforated plate and that divides the inflowing jet of water into a multiplicity of individual jets. For this purpose, perforated plate 2 has a corresponding number of flow holes 3 that, at least in a section of the holes at the flow inlet side, are tapered in the direction of flow, preferably conically. So that dirt particles cannot penetrate into fitting 1 and cause functional disturbances there, a sieve attachment 17 is provided at the flow inlet side.
Jet regulating device 4 of jet regulator 1 (shown here) has a modular construction. A plurality of insert parts 5 that can optionally be combined with one another are allocated to jet regulating device 4. Thus, insert parts 5 a and 5 b shown in FIGS. 2 and 3 comprise grid-shaped webs 11. The grid structures of these insert parts 5 a, 5 b are offset to one another by approximately 45°, and insert part 5 b, shown in FIG. 3, has a smaller grid spacing in comparison with insert part 5 a from FIG. 2. A correct positioning of insert parts 5 in relation to one another in mounting housing 6 is ensured at all times by position-orienting projections or recesses 13 on the outer peripheral edge of insert parts 5 a, 5 b, working together with position-orienting recesses or projections on the housing inner periphery of the housing part 8.
FIG. 13 shows that jet regulating device 4 can also have two adjacent insert parts 5 a, 5 b whose webs 11 and intersect nodes 10 align with one another. Here, it is clear from FIG. 13 that insert parts 5 a, 5 b of such a jet regulating device 4 can also be formed with identical construction, further reducing manufacturing costs. As in FIGS. 4 and 8, in FIG. 13 circles printed in bold indicate that the flow openings of perforated plate 2 align with the intersect nodes 10 of at least one insert part that is connected downstream in the direction of flow. The circles printed in bold in FIG. 13 illustrate the impingement points of the individual jets coming from jet fractionating device 2 on intersect nodes 10 of insert part 5 a.
From FIG. 14, it can be seen that, if necessary, jet regulator 1 can also be used without a jet regulating device situated downstream from jet fractionating device 2. Here, jet fractionating device 2 of jet regulator 1, shown in FIG. 14, is not realized as a perforated plate, but rather has a central baffle plate 18 having radially oriented flow openings 19 on its edge. These radially oriented flow openings 19 are directed towards a peripheral wall 20 that is constructed so as to be open towards the flow outlet side, and that surrounds baffle plate 18 at a distance. While first housing part 7 is connected to jet fractionating device 2, in second housing part 8, at the flow outlet end thereof, only one honeycomb-shaped flow rectifier 14 is provided, which can be placed into housing part 8 from the flow inlet side up to a support situated on the edge.
