Background Art

[0002] A jet regulator is previously known from DE19647798A1, which can be mounted on the water outlet of a sanitary water outlet fitting in order to shape the outflowing water into a uniform, non-splashing and, if necessary, softly foaming water jet. In order to be able to mount the previously known jet regulator on the water outlet of a sanitary water outlet fitting, the jet regulator is configured as an embedding cylinder, the cylindrical jet regulator housing of which is configured as a plastic injection molded part can be embedded in a sleeve-shaped water outlet spout piece, the water outlet spout piece having an external thread or an internal thread, which can be screwed onto a corresponding thread on the water outlet of the sanitary water outlet fitting. The threaded connection provided between the water outlet spout piece and the water outlet part causes a circular cross section of the water outlet spout piece and the jet regulator housing that can be embedded in the water outlet spout piece. A jet splitter having a plurality of splitter openings spaced apart from each other is provided inside the jet regulator housing, and the water flowing into the water pipeline is divided into a corresponding number of single jets in the splitter openings. A fluid rectifier is provided on the water outlet side of a previously known jet regulator, and the fluid rectifier has a plurality of water outlet openings so that a single jet that generates eddies and is mixed with ambient air when necessary in the interior of a housing is formed into a uniformly discharged water jet. In order to enable each single jet to additionally generate eddies, brake and, when necessary, be mixed with ambient air in the interior of the housing, a jet regulating device is provided in the flow path between the jet decomposer and the fluid rectifier in the interior space of the housing, and the jet regulating device has a regulating tab oriented transversely to the flow direction of the through-flowing water. In the previously known jet regulator, the fluid rectifier and the jet regulating device forming the water outlet side of the jet regulator are both formed by a screen disc composed of a metal braid. The screen opening of the screen disc forming the fluid rectifier forms the water outlet opening, and the metal wires interwoven with each other of the screen disc constituting the jet regulating device form its regulating tab. Here, the screen discs are embedded into the interior space of the jet regulator housing from the water outlet end side, and then the water outlet side mouth edge of the jet regulator housing is bent inward by the heat applied to the plastic material used for the jet regulator housing, so that the screen discs are held in the jet regulator housing in a captive manner.

[0003] A jet regulator is known from EP 0 931 199 B1, which has a jet splitter on the inflow side and a fluid rectifier on the outflow side in its jet regulator housing, wherein a jet regulator is arranged in the flow path between the jet splitter and the fluid rectifier. The jet regulator of this previously known jet regulator also has a pin-shaped or web-shaped impact body, wherein the pin or web used as the impact body either protrudes from the inner side of at least one peripheral section of the jet regulator housing and is connected to the jet regulator housing in one piece, or protrudes at a right angle beyond the flat side of a neck part, which can be embedded in the sleeve-shaped jet regulator housing by bending. However, this previously known jet regulator is associated with considerable expenditure in terms of design and production. Summary of the invention

[0004] The object is therefore to provide a jet regulator of the type mentioned in the introduction, the components of which can be produced as simply as possible even in the case of a relatively complex design of the jet regulator.

[0005] The solution according to the invention to the task, in the case of a jet regulator of the type mentioned at the outset, consists in that in particular the flow rectifier and the jet regulating device can be embedded in the jet regulator housing from the outflow side of the jet regulator, the jet regulating device has at least one inner wall, the regulating web is integrally formed onto the inner wall on the flat side, and the flow rectifier and / or the jet regulating device can be fixed in the jet regulator housing by means of a form fit or a friction fit.

[0006] The jet regulator according to the present invention has a jet regulator housing, which can be embedded in the water outlet of a sanitary water outlet fitting, so that the water discharged there is formed into a uniform, non-splashing and, if necessary, also foaming-soft water jet. The jet regulator housing according to the jet regulator of the present invention surrounds and limits the housing interior space, and a jet splitter with a splitter opening is provided in the housing interior space. In the splitter opening, the water flowing through is divided into a plurality of single jets. These single jets are additionally braked and divided in the subsequent jet regulating device inside the jet regulator housing, and then the water flowing through is merged into a soft, uniform total jet in the subsequent fluid rectifier again. The fluid rectifier with a plurality of water outlet openings forms the water outlet end side of the jet regulator. In the housing interior space, the jet regulating device is arranged in the flow path between the jet splitter and the fluid rectifier, and the jet regulating device has a regulating splice oriented transversely to the flow direction of the water flowing through. The fluid rectifier and the jet regulating device can be embedded in the jet regulator housing from the outflow end side of the jet regulator. In order to keep the regulating tab transverse to the flow direction of water in the flow path, the jet regulating device has at least one inner wall, and the regulating tab is integrally formed on the inner wall on the flat side. The jet regulating tab together with its at least one inner wall and the regulating tab integrally formed on the inner wall, as well as the jet regulator housing and the remaining components of the jet regulator according to the present invention can be manufactured as injection molded parts in a simple manner without complex injection molding molds to manufacture these components. Here, the fluid rectifier and / or the jet regulating device are fixed in the jet regulator housing by means of form locking or friction locking.

[0007] According to a particularly advantageous and easily producible embodiment of the invention, it is provided that the flow straightener and / or the jet regulating device can be fixed in the jet regulator housing by means of a snap-in or snap-in connection. The positive fit between the flow straightener and / or the jet regulating device on the one hand and the jet regulator housing on the other hand, which is formed by the snap-in or snap-in connection, ensures a secure and load-bearing connection of these components of the jet regulator according to the invention.

[0008] The jet regulator according to the invention can have a jet regulator housing which is circular in cross section with a likewise circular jet outlet. However, embodiments are preferred in which the jet regulator is designed as a rectangular or flat jet regulator and / or has a non-circular jet outlet which has a greater longitudinal extension than a transverse extension.

[0009] In order to enable the jet regulating device to be positioned appropriately inside the jet regulator housing, it is advantageous if at least one guide groove open toward the water outlet end of the jet regulator is provided on the inner circumference of the jet regulator housing, wherein the at least one inner wall can be introduced into the guide groove with one of its narrow edges oriented in the embedding direction.

[0010] In addition, a simple installation of the jet regulator according to the invention is facilitated if the jet regulator housing has a guide groove on opposite sides of its housing inner circumference, each of which is open toward the water outlet end, and if the at least one inner wall can be introduced into the guide groove with its narrow edge oriented in the insertion direction. In this embodiment, a well-positioned installation of the inner wall with the regulating tab integrally formed thereon is ensured in a simple manner.

[0011] The adjusting tab can be integrally formed on one of the two flat sides of the at least one inner wall. However, according to an embodiment of the invention which is particularly simple in design and production, it is provided that the adjusting tab is integrally formed on both flat sides on the at least one inner wall.

[0012] In order to shape the water flowing along the jet regulating device and its regulating webs in a desired manner, it is advantageous if the regulating webs are integrally formed on at least one flat side of the at least one inner wall in levels oriented transversely to the flow direction and preferably spaced apart from one another.

[0013] If the regulating webs arranged in the outflow-side level are arranged on the recesses in the extension of the flow spaces arranged between adjacent regulating webs of the web level arranged on the inflow side, the throughflowing water can be shaped particularly well in the successive web levels of the jet regulating device.

[0014] In order to brake the individual jets from the jet splitter quickly and also to divide them, it is advantageous if the regulating webs of the first web level in the flow direction each have an inflow-side impact surface and / or are rounded on their outflow side.

[0015] In order to subsequently reunite the water jets that have been braked and additionally divided in the jet regulating device, it is advantageous if the regulating webs arranged at the web level on the outflow side in the flow direction have a longitudinal extension oriented in the flow direction that is larger than the web width and / or that the regulating webs are rounded on their inflow side and / or on their outflow side.

[0016] In particular, when the jet regulator according to the invention is designed as a rectangular or flat jet regulator, it may be advantageous if the regulating webs arranged on the web level on the outflow side in the throughflow direction have a longitudinal extension that is curved in the direction of the adjacent transverse wall of the jet regulator housing. The flat jet formed in such a rectangular or flat jet regulator maintains its shape even over a relatively long distance of the outflowing water if the water flowing through the jet regulator housing is also well guided in the region of the jet regulating device into the edge region of the flat jet that flows along the transverse wall of the jet regulator housing.

[0017] Here, according to a particularly advantageous embodiment of the invention, it is provided that the curvature of adjacent adjusting webs is greater in the case of outer adjusting webs which are arranged closer to the adjacent transverse wall than in the case of corresponding inner adjusting webs, in which embodiment the outflowing water is discharged as a uniform flat jet even over a longer stroke and the water is well distributed over the entire jet cross section.

[0018] According to a preferred embodiment of the present invention, in which the regulating webs of the jet regulating device are arranged in at least three web levels, it is provided that the regulating webs of the web level arranged between the first web level and the web level arranged on the outflow side in the flow direction have a rounded and preferably circular web cross section. In this web level, the water flowing through is additionally braked and divided without having to worry about excessively strong eddies in the water flow.

[0019] In order to enable the fluid rectifier arranged at the water outlet end side to homogenize and merge the water flowing out there into a uniform total jet, and the fluid rectifier does not cause the incoming water to resist excessive flow resistance, it is advantageous that the fluid rectifier has a grid structure composed of a plurality of groups of rectifier webs that cross each other, and each rectifier web defines a water outlet opening between each other.

[0020] In this case, the water flowing through can be shaped particularly well in the flow rectifier if the rectifier webs of the grid structure have a longitudinal extension oriented in the flow direction that is greater than the web width.

[0021] In this case, a uniform shaping of the outflowing water jet is facilitated if the rectifying web is arranged “on the gap” in the extension of the flow space between adjacent regulating webs arranged at the web level on the outflow side.

[0022] In a particularly simple embodiment, the jet splitter is either embedded in the jet regulator housing from the inlet side of the jet regulator to an annular step arranged on the inner circumference of the housing or can be integrally formed on the inner circumference of the jet regulator housing. In this embodiment, it is provided that the jet splitter is configured as a perforated plate having a splitter opening oriented in the flow direction.

[0023] In order that the regulating webs arranged in the first web level on the inflow side can already fulfill their function particularly well, it is advantageous if the jet splitter is arranged in the jet regulator housing relative to the regulating webs of the first web level on the inflow side such that they are arranged aligned with the splitter opening in the flow direction.

[0024] In order to allow the individual jets emerging on the outflow side of the jet splitter to expand unhindered and to mix with one another in the mixing zone, it is advantageous if at least two web-shaped spacers extend from the narrow edge of the inflow side of the inner wall or on the outflow side of the jet splitter, which spacers keep the narrow edge of the inflow side spaced from the jet splitter. These web-shaped spacers ensure that there is sufficient spacing between the outflow side of the jet splitter on the one hand and the inner wall on the other hand, so that a mixing zone can be formed in the housing interior of the jet regulator housing in this region.

[0025] According to a preferred embodiment of the invention, it is provided that the flow straightener and the jet regulating device are connected to one another in one piece or form separate components of the jet regulator.

[0026] If these components are to be manufactured as separate components and if these components are to be connected to one another when they are installed in the jet regulator housing, it may be advantageous that the flow rectifier and the jet regulating device, which are designed as separate components, can be connected to one another and that for this purpose at least one plug-in pin, preferably at least two plug-in pins spaced apart from one another, project from one of the components and can be inserted into a corresponding insertion opening on the other component.

[0027] In this context, design and assembly are significantly easier in a preferred embodiment which provides that the plug-in pin projects over a narrow edge of the inner wall on the outflow side and can be inserted into an associated insertion opening on the flow rectifier.

[0028] The jet control device can also be mounted with its inner wall on the fluid regulator in a captive and possibly also non-detachable manner when the plug-in bolt can be inserted into the associated insertion opening until the cross-sectional expansion provided on the free bolt end of the plug-in bolt protrudes beyond the fluid regulator. The fluid regulator is held securely and firmly on the inner wall of the jet control device by the cross-sectional expansion, which protrudes in a harpoon-like manner beyond the outflow side of the jet regulator in the mounted state of the jet regulator.

[0029] Advantageously, the inner wall is divided into at least two wall sections with webs integrally formed on the flat side. The at least two sections are then introduced successively into guide grooves on the housing inner circumference of the jet regulator housing until the inner wall formed by the wall sections is formed.

[0030] According to an embodiment of the invention that is particularly easy to produce, it is provided that the inner wall is divided into wall segments on which at least one level of adjusting webs is integrally formed. In this embodiment, the adjusting webs arranged in the individual web levels can be well formed with different web cross sections despite relatively small spacings.

[0031] It may be advantageous if the at least one inner wall is arranged in the jet regulator housing in such a way that the inner wall is at a greater distance from a first longitudinal wall of the jet regulator housing than from a second longitudinal wall.

[0032] In order to distribute the water flowing through the jet regulator according to the invention well and evenly over the entire housing cross section even in this embodiment, it can be advantageous if the longitudinal axis of the splitter opening of the jet splitter is oriented approximately to the web center of adjacent regulating webs. Thus, even if the at least one inner wall is spaced at different distances from the longitudinal walls of the jet regulator housing arranged on both sides, even if the longitudinal axis of the splitter opening of the jet splitter is oriented approximately to the web center of adjacent regulating webs and if the splitter openings arranged in rows spaced apart from one another are oriented obliquely to the longitudinal extension of the jet regulator housing in at least one row of said splitter openings, an even distribution of the water flowing through over the entire housing cross section is ensured.

[0033] It may be advantageous if the flow straightener and / or the jet regulating device is designed as a two-component or multi-component injection-molded part and / or is produced from an elastomeric plastic.

[0034] According to a preferred embodiment of the invention, it is provided that at least one partial region of the rectifier web is produced from an elastomeric plastic or has at least one surface produced from an elastomeric plastic.

[0035] Further developments according to the invention are apparent from the accompanying drawings and the subsequent description of the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] exist Figures 1 to 23101, 106, 110, 115, 118 and 121 of the jet regulator are shown. The jet regulator 101, 106, 110, 115, 118 and 121 have a jet regulator housing 1, which can be embedded in the water outlet of the sanitary water outlet fitting not further shown here, so as to shape the water discharged there into a uniform, non-splashing and, if necessary, also foaming soft water jet. The jet regulator housing 1 surrounds and defines the housing interior space, in which a jet splitter 2 with a splitter opening 3 is provided. In the embodiments 101, 106, 110, 115, 118 and 121 shown here, the plate-shaped jet splitter 2 is integrally formed with its splitter opening 3 on the inner periphery of the jet regulator housing 1 in one piece. The water flowing through is divided into a plurality of single jets in the splitter opening 3. These single jets are additionally braked and divided in the subsequent jet regulating device 4 inside the jet regulator housing 1, and then the water flowing through in this way is merged again into a soft and uniform total jet in the subsequent fluid rectifier 5. The fluid rectifier 5 with multiple water outlet openings 6 forms the water outlet end side A of the jet regulator 101, 106, 110, 115, 118 or 121. In the interior space of the housing, the jet regulating device 4 is arranged in the flow path between the jet splitter 2 and the fluid rectifier 5, and the jet regulating device has an adjustment bar 7 oriented transversely to the flow direction of the water flowing through. The fluid rectifier 5 and the jet regulating device 4 can be embedded in the jet regulator housing 1 from the water outlet end side A of the jet regulator. In order to enable the adjustment bar 7 to remain transverse to the flow direction of the water during the flow path, the jet regulating device 4 has at least one inner wall 8, and the adjustment bar 7 is integrally formed on the inner wall on the flat side. The jet regulating device 4 with its at least one inner wall 8 and the regulating tab 7 integrally formed thereon can be manufactured in a simple manner as an injection molded part and in particular as a plastic injection molded part, together with the remaining components of the jet regulator housing 1 and the jet regulators 101, 106, 110, 115, 118, 121 shown here, without requiring a complex injection mold to produce these components. Here, the flow rectifier 5 and the jet regulating device 4 are fixed to the inner circumference of the jet regulator housing 1 by means of a positive fit or a friction fit, so that these components 4, 5 cannot accidentally fall out of the jet regulator housing 1 even under the pressure of the inflowing water.

[0062] exist Figure 2, 7, 11, 16, 19 and 21, it can be seen that the jet regulator shown here has a pre-screen 9 on the inflow side of its jet regulator housing 1, which filters out calcium particles and dirt particles that may be carried in the inflowing water before they can have a negative impact on the function of the jet regulator inside the housing. A flow regulator 10 can be arranged between the pre-screen 9 and the jet splitter 2, which adjusts the flow capacity of water flowing from the inflow side of the jet regulator housing 1 to the opposite water outlet end side A to a determined maximum value independently of the pressure. In the embodiments 101, 106, 110, 115, 118 and 121 shown here, the jet regulator is respectively configured as a rectangular or flat jet regulator and has a non-circular jet outlet, which has a larger longitudinal extension than the transverse extension. In order to position the jet regulating device 4 in a suitable position inside the jet regulator housing 1, at least one guide groove 11 is provided on the inner circumference of the housing of the jet regulator housing, which is open toward the outlet end side A of the jet regulator, and into which at least one inner wall 8 of the jet regulating device 4 can be introduced with one of its narrow edges oriented in the insertion direction. In order to also facilitate the simple installation of the jet regulator shown here, the jet regulator housing 1 of the jet regulator embodiments 101, 106, 110, 115, 118, 121 shown here has a guide groove 11 open toward the outlet end side A on the opposite side of the housing inner circumference, wherein the at least one inner wall 8 can be introduced with its narrow edge oriented in the insertion direction into the guide groove 11. In this way, the suitable installation of the inner wall 8 together with the regulating tab 7 integrally formed thereon is ensured in a simple manner.

[0063] The regulating webs 7 are integrally formed on both sides on the flat side onto the at least one inner wall 8. In order to be able to shape the water flowing along the jet regulating device 4 and its regulating webs 7 in a desired manner, the regulating webs 7 are integrally formed on at least one flat side of the at least one inner wall 8 in layers oriented transversely to the flow direction and preferably spaced apart from one another. In order to be able to shape the water flowing through the jet regulator housing 1 particularly well in the layers of successive webs of the jet regulating device 4, the regulating webs 7 arranged in the layer on the outflow side are arranged on the recesses in the extension of the flow spaces arranged between adjacent regulating webs relative to the layer of webs arranged on the inflow side.

[0064] In order to brake the individual jets from the jet splitter 2 quickly and also to divide them, the regulating webs 7 of the first web level in the flow direction each have an inflow-side impact surface 12 and are rounded on their outflow side.

[0065] In order to subsequently reunite the water jets braked and additionally divided in the jet regulating device 4, the regulating webs 7 arranged at the web level on the outflow side in the flow direction have a longitudinal extension oriented in the flow direction that is larger than the web width and are rounded both on their inflow side and on their outflow side.

[0066] In the jet regulator embodiments 101, 106, 110, 115, 118, 121 shown here, the regulating webs 7 of the middle web level arranged between the first web level and the web level arranged on the outflow side in the flow direction have a rounded and preferably circular web cross section. In this middle web level, the water flowing through is additionally braked and divided without having to worry about excessively strong eddies in the water flow.

[0067] In order to make the flow straightener 5 arranged at the water outlet end side A and formed in the form of a plate here to homogenize and merge the water flowing out there into a uniform total jet, and the flow straightener 5 does not make the water flowing in resist excessive flow resistance, the flow straightener 5 of the jet regulator 101, 106, 110, 115, 118, 121 shown here has a grid structure composed of a plurality of groups of cross-connected straightener webs 13, each of which defines the water outlet opening 6 of the flow straightener 5 between each other. In order to shape the water flowing through the flow straightener 5 into a uniformly discharged jet band, the straightener webs 13 of the grid structure have a longitudinal extension dimension oriented in the flow direction that is larger than the web width. Here, by arranging the straightener webs 13 on the gap in the extension of the flow space between adjacent regulating webs 7 arranged on the web level on the outflow side, it is conducive to the shaping of the uniform water outlet jet.

[0068] In order that the regulating webs 7 arranged in the first web level on the inflow side can already fulfill their function particularly well, the jet splitter 2 is arranged in the jet regulator housing 1 relative to the regulating webs 7 of the first web level on the inflow side so that they are arranged aligned with the splitter openings 3 in the flow direction.

[0069] In order to allow the individual jets emerging on the outflow side of the jet splitter 2 to expand unhindered and to mix with one another in the mixing zone, at least two web-shaped spacers 14 project on the outflow side of the jet splitter or, as in this case, on the narrow edges of the inflow side of the inner wall 8, which spacers keep these narrow edges of the inflow side spaced apart from the jet splitter 2. These web-shaped spacers 14 ensure that there is sufficient spacing between the outflow side of the jet splitter 2 on the one hand and the inner wall 8 on the other hand, so that a mixing zone can be formed in this region in the housing interior of the jet regulator housing 1.

[0070] exist Figures 1 to 5In the jet regulator embodiment 101 shown in the drawing, the flow straightener 5 and the jet regulating device 4 are connected to each other in one piece, while the flow straightener 5 and the jet regulating device 4 of the remaining jet regulator embodiments 106, 110, 115, 118 and 121 form separate components or parts of the jet regulator.

[0071] exist Figures 15 to 17 In the jet regulator embodiment 115 shown in the drawing, the fluid rectifier 5 and the jet regulating device 4, which are made as separate components, can be connected to each other. For this purpose, at least two plug-in bolts 15 spaced apart from each other are provided on one of the components, here on the inner wall 8 of the jet regulating device 4, and the plug-in bolts can be inserted into the corresponding insertion openings 16 on the other component, here on the fluid rectifier 5. The plug-in bolts 15 extend out on the narrow edge of the outflow side of the inner wall 8 and can be inserted into the corresponding insertion openings 16 on the fluid rectifier 5, until the cross-sectional expansion provided on the free bolt end of the plug-in bolt 15 extends beyond the fluid rectifier 5. By means of the cross-sectional expansion, which extends out in a harpoon-like manner beyond the outflow side of the jet regulator 115 in the installed state of the jet regulator, the fluid rectifier 5 is securely and firmly held on the inner wall 8 of the jet regulating device 4.

[0072] exist Figures 18 to 20 In the jet regulator embodiment 118 shown in the drawing, the inner wall 8 is divided into at least two wall segments and here is divided into three wall segments 17, and the regulating tabs 7 are integrally formed on each wall segment 17. The wall segments 17 are introduced into the guide grooves 11 on the inner circumference of the housing of the jet regulator housing 1 one by one until the inner wall 8 formed by these wall segments 17 is formed. One layer of the regulating tab 7 is integrally formed on each wall segment 17. Figures 18 to 20 In the embodiment 118 of the jet regulator shown in FIG. 1 , the regulating webs 7 arranged in the individual web levels can be designed well with different web cross sections despite the relatively small spacings.

[0073] exist Figures 1 to 5 In the jet regulator embodiment 101 shown in the figure, the plate-shaped fluid rectifier 5 together with the inner wall 8 of the jet regulating device 4 integrally formed at a right angle on the fluid rectifier is embedded into the housing interior space of the jet regulator housing 1 from the outflow side A of the jet regulator 101 until the latching protrusions arranged on the outer circumference of the fluid rectifier 5 are snapped into the complementary latching grooves on the housing inner circumference of the jet regulator housing. Through this form-fitting connection of the fluid rectifier 5 on the housing inner circumference of the jet regulator housing 1, the jet regulating device 4 integrally formed on the fluid rectifier 5 is also fixed in the housing interior space.

[0074] In a comparable way, Figures 15 to 17 The jet regulating device 4 of the jet regulator embodiment 115 shown in the drawing can also be fixed in the housing interior space of the jet regulator housing 1. If the jet regulating device 4 is connected to the fluid rectifier 5, these components 4, 5 can be reliably and firmly held in the jet regulator housing 1 if, in addition or instead of this, a latching or snap-fit ​​connection structure that cooperates with the housing inner circumference of the jet regulator housing 1 is provided on the inner wall 8 of the jet regulating device 4 and in particular on the narrow side of the inner wall 8.

[0075] In jet regulator implementation schemes 106, 110, 118 and 121, the jet regulating device 4 is first pushed into the jet regulator housing 1 from the outflow side, and then the plate-shaped fluid rectifier 5 is embedded in the jet regulator housing 1 and snapped or buckled onto the inner circumference of the jet regulator housing 1, so that the jet regulating device 4 is also reliably and firmly held in the internal space of the jet regulator housing 1.

[0076] In order to form the flat jet that flows out of the jet regulator housing 1 with a sufficient amount of water in the edge region of its narrow side, Figures 21 to 23 In the jet regulator implementation scheme 121 shown in the figure, the regulating web 7 arranged at the web level on the outflow side along the flow direction has a longitudinal extension dimension that is bent toward the adjacent transverse wall 18 of the jet regulator housing 1, wherein the curvature of the adjacent regulating web 7 is greater in the outer regulating web 7 arranged closer to the transverse wall 18 than in the corresponding inner regulating web 7.

[0077] Depend on Figure 4 and 5 1 , it becomes clear from a comparison that the jet regulator shown here, and in particular the jet regulator embodiment 101 here, has at least one slot-shaped ventilation opening 21 only on one of its longitudinal walls 19 and here only on its longitudinal wall 19 facing away from the user in the use position, which ventilation opening opens into the mixing zone arranged below the jet splitter 2 in the flow direction and through which ambient air can flow into the housing interior of the jet regulator housing 1. For this purpose, the jet regulator housing 1 has an inwardly shaped portion 20 on its housing periphery on the longitudinal wall 19 facing away from the user in the use position, which inwardly shaped portion leads from the outlet side A of the jet regulator housing to the ventilation opening 21. If the inner wall 8 is now arranged approximately in the longitudinal center plane of the jet regulator housing 1, this results in the inner wall 8 having a greater spacing relative to the longitudinal wall 19 facing away from the user in the use position and having the ventilation opening 21 than the longitudinal wall 19 facing away from the user in the use position. In order to ensure that the water flowing through can nevertheless flow through in a manner evenly distributed over the cross section of the jet regulator housing 1, Figures 21 to 23In the jet regulator embodiment 121 shown in the drawing, it is provided that the longitudinal axis of the splitter opening 3 of the jet splitter 2 is oriented approximately toward the web center of the adjacent regulating web 7. Although the regulating web 7 extending with its free web end to the adjacent longitudinal wall 19 has different web lengths on both sides of the inner wall 8, the water flowing through is evenly distributed over the cross section of the jet regulator housing 1 because the longitudinal axes of the splitter openings 3 of the jet splitter 2 are oriented approximately toward the web center of the adjacent regulating web 7.

[0078] In order to counteract excessive calcification of the regulating web 7 and / or the rectifier web 13, the flow rectifier 5 and / or the jet regulating device 4 can be designed as a two-component or multi-component injection-molded part and in particular made of an elastomeric plastic 22. Figures 11 to 14 In the embodiments shown in FIGS. 15 to 17 , the flow rectifier 5 is formed as a two-component injection-molded part, wherein the hard elastic plastic part 23 shown in the figure with dotted lines forms a frame that reinforces the flow rectifier, while the outer periphery of the flow rectifier 5, which is wetted by water and / or rests on the inner periphery of the housing, is made of an elastomeric plastic 22, which is indicated here with cross-hatching and has a significantly brighter effect, at least on the surface. In this regard, an embodiment is preferred in which at least a subregion of the rectifier web 13 is made of an elastomeric plastic 22 or has at least one surface made of an elastomeric plastic 22.
