Description

Technical Field

[0001] The present invention relates to a sanitary valve having a main valve with a movable diaphragm that can move between a closed position and at least one open position. In the closed position, the diaphragm is placed sealingly on the valve seat of the main valve, and in the open position, the diaphragm is spaced apart from the valve seat. Background Art

[0002] A sanitary valve of the type mentioned at the beginning is already known from DE 10 2017 105 200 A1, which can be interposed into the water path of a water supply line for switching on or switching. For this purpose, the pre-known sanitary valve has a main valve, the valve inlet of which is connected to the inflow-side line section, and the valve outlet of which is connected to the outflow-side section of the water path. The main valve has a movable diaphragm that is placed sealingly on the valve seat in the closed position of the main valve and releases the valve seat in the open position. The pre-known sanitary valve also has a pilot valve by means of which the main valve can be controlled between the open position and the closed position. Here, the position of the diaphragm can be preset by the position of a valve tappet that is in control connection with a push-push mechanism by means of which the valve tappet can be switched between a switching position corresponding to the open position and a switching position corresponding to the closed position. Between the open position and the closed position, the push-push mechanism can also preset intermediate positions stepwise in which the diaphragm is held at different distances from the valve seat, thereby releasing a reduced flow cross-section relative to the open position. However, in this pre-known sanitary valve, stepless flow regulation of the amount of water flowing through the main valve or even regulation and mixing of liquids flowing in from different liquid inlets is not feasible.

[0003] A sanitary valve unit is pre-known from DE 10 2016 115 793 A1, which can be assembled, for example, in a faucet for a bathroom. This pre-known valve unit is installed in the faucet body of the faucet and has a temperature regulating valve, a water-saving valve, and a contact element. Here, the temperature regulating valve is installed in the assembly chamber of the faucet body. The temperature regulating valve has an inlet part, a mixing chamber, and an outlet part. Cold water and hot water flow into the inlet part, and are mixed in the mixing chamber in a preset ratio to form mixed water, from where the mixed water flows out via the outlet part. The temperature regulating valve of this pre-known valve unit includes an internal inlet valve seat, a mixing valve insert, and a temperature regulating valve socket body. The internal inlet valve seat is provided with a cold water inlet flow-through channel and a hot water inlet flow-through channel. Cold water flows into the cold water inlet flow-through channel, and hot water flows into the hot water inlet flow-through channel. The cold water inlet flow-through channel and the hot water inlet flow-through channel form the inlet part of this pre-known valve unit. Here, the inlet valve seat is fixedly connected to the lower end of the mixing valve insert. The mixing chamber and the mixed water outlet flow-through channel communicating with the mixing chamber are bounded inside the mixing valve insert, and the mixed water outlet flow-through channel is located in the outlet part. The temperature regulating valve socket body can be pulled rotatably in a limited manner above the mixing valve insert within a preset angular range and axially bounds between the mixing valve insert and the inlet valve seat. The cold water flow-through channel and the hot water flow-through channel are bounded between the temperature regulating valve socket body and the mixing valve insert. If the temperature regulating valve socket body rotates, the flow rate of the water flowing between the cold water flow-through channel and the cold water inlet flow-through channel and the flow rate of the water flowing between the hot water flow-through channel and the hot water inlet flow-through channel can be directly adjusted, so as to control the mixing ratio of the cold and hot water flowing towards the mixing chamber and the mixed water temperature.

[0004] Since the valve unit pre-known from DE 10 2016 115 793 A1 has a temperature regulating valve and a water-saving valve, and since the temperature regulating valve of this pre-known valve unit and its inlet part, mixing chamber, and outlet part are assembled from a plurality of separate components, this pre-known sanitary valve unit has a relatively large installation length. Summary of the Invention

[0005] Therefore, the object of the present invention is to provide a sanitary valve of the type initially mentioned, which, in addition to the closing function for opening and closing the water outlet, also allows the mixing function of mixing water (such as hot water and cold water) flowing in from different inflow pipelines, or allows adjusting the amount of liquid flowing out per unit time from the sanitary valve according to the present invention, and still has the advantages of a compact structural form and a relatively short installation length.

[0006] In a sanitary valve of the type mentioned at the beginning, the solution according to the invention for this purpose lies in particular in that the main valve is arranged inside the housing of an inner housing, which inner housing is rotatably supported in an outer housing about a rotational axis; a first valve opening is provided in the inner housing, which first valve opening is connected in a fluid-conducting manner to a first valve opening in the outer housing to form a valve outlet, and this pair of first valve openings is arranged along the rotational axis of the outer housing and the inner housing; the inner housing has at least one second valve opening, which at least one second valve opening is arranged externally with respect to the valve outlet and is assigned to at least one second valve opening in the outer housing to form at least one valve inlet; the mutually assigned second valve openings can be brought into coincidence by relative rotation of the inner housing and the outer housing, such that the net opening cross-section through which the at least one valve inlet is unobstructed by the coincidence of the mutually assigned second valve openings can be changed; the inner housing has a basin-shaped lower housing part, on the inner side of the bottom of which a valve connection piece projects, which valve connection piece connects the first valve opening forming the valve outlet of the inner housing to a valve seat formed by the free sleeve end region of the valve connection piece; and the lower housing part of the inner housing having the valve opening of the inner housing is in liquid-tight abutment against the outer housing at least in an annular region of the bottom of the inner housing which is external to the valve opening and / or on the outer peripheral edge of the inner housing.

[0007] The sanitary valve according to the invention has an inner housing, which is rotatably supported in an outer housing. A main valve is provided inside the housing of the inner housing. The main valve has a movable diaphragm that can move between a closed position and at least one open position. In the closed position, the diaphragm seals against the valve seat of the main valve, and in the open position, the diaphragm is spaced apart from the valve seat. Thus, by means of the main valve, the liquid outlet in the sanitary valve according to the invention is selectively or alternately opened or closed. The inner housing rotatably supported in the outer housing about a rotation axis has a first valve opening, which is connected in a liquid-guiding manner to a first valve opening in the outer housing to form the valve outlet of the main valve. This pair of first valve openings is arranged along the rotation axis between the outer housing and the inner housing. The valve housing also has at least one second valve opening, which is arranged externally relative to the valve outlet of the sanitary valve according to the invention and is paired with at least one second valve opening in the outer housing to form at least one valve inlet. In order to regulate the volume flow of the liquid flowing through the sanitary valve via the at least one valve inlet and / or in order to be able to mix liquids with different properties, such as hot water or cold water, the mutually paired second valve openings can be brought into coincidence by relative torsion of the inner housing and the outer housing, so that the net opening cross-section through which the at least one valve inlet is unobstructed by the coincidence of the mutually paired second valve openings can be changed. Here, the inner housing has a basin-shaped lower housing part, and a valve connection pipe projects from the inner side of the bottom of the basin of the lower housing part. The valve connection pipe connects the first valve opening forming the valve outlet of the inner housing to a valve seat formed by the free sleeve end region of the valve connection pipe. In this way, a liquid chamber is formed between the valve connection pipe and the inner peripheral edge of the lower housing part. In one design of the sanitary valve according to the invention, the liquid chamber can also be used as a mixing chamber. Here, the lower housing part of the inner housing with the valve opening of the inner housing is at least liquid-tightly abutted against the outer housing in the annular region of the bottom of the basin relative to the valve opening externally and / or by means of the outer peripheral edge of the lower housing part.

[0008] In order to additionally promote the compact structural form of the sanitary valve according to the invention, it can be advantageous that the outer housing has a preferably disc-shaped or plate-shaped housing bottom, and the lower housing part of the inner housing is at least liquid-tightly and torsionally abutted against the housing bottom by means of its outer annular region and / or peripheral region. In this embodiment form according to the invention, the disc-shaped or plate-shaped housing bottom can be constructed as a simple solid member except for the valve openings provided therein.

[0009] In order to make the lower part of the inner housing liquid-tightly abut against the outer housing at least in the external annular region of the basin bottom and / or by means of its housing outer periphery, it is advantageous if the lower part of the housing of the inner housing and / or the housing bottom of the outer housing are made of ceramic. Here, if the lower part of the housing and preferably also the housing bottom are made of ceramic, these components of the outer housing and the inner housing abut against each other in a wear-free and liquid-tight manner.

[0010] In order to enable the water flowing through the liquid chamber or mixing chamber in the lower part of the housing to flow out well from this liquid chamber or mixing chamber, it is advantageous if the first valve openings of the outer housing and the inner housing have a circular and / or conforming opening cross-section at least in the region where they are adjacent to each other.

[0011] In order to be able to adjust the volume capacity flowing through the sanitary valve according to the invention, it is advantageous if the second valve opening in the inner housing, which is connected in a liquid-guiding manner to at least one second valve opening in the outer housing, is configured as a sickle-shaped or arcuate slot.

[0012] A preferred embodiment of the sanitary valve according to the invention provides that the sanitary valve is configured as a shut-off and mixing valve or as a shut-off and regulating valve.

[0013] In order to be able to configure the sanitary valve according to the invention as a shut-off and mixing valve, it is advantageous if the first valve opening in the inner housing is matched with at least two second valve openings in the outer housing such that by relative torsion of the inner housing and the outer housing, the net opening cross-section between the second valve opening in the inner housing and at least one second valve opening provided in the outer housing can be reduced and at the same time the net opening cross-section can be increased relative to the second valve opening in the inner housing and at least one further valve opening among the second valve openings provided in the outer housing, and vice versa.

[0014] If the sanitary valve according to the invention is configured as a shut-off and mixing valve, then it is advantageous if the second valve openings provided in the outer housing can be connected to different liquid supply devices, for example for hot water and cold water.

[0015] If the annular space provided between the valve connection and the inner peripheral edge of the housing of the lower part of the housing forms a mixing chamber, then this contributes more to a simple, low-maintenance and compact structural form of the sanitary valve according to the invention.

[0016] Another proposal for achieving the above object in a sanitary valve of the type mentioned at the beginning provides that the lower part of the housing is connected to the one-piece, two-piece or multi-piece upper part of the inner housing, the diaphragm is clamped in the clamping region between the lower part of the housing and the upper part of the inner housing, and the diaphragm seals at least by means of its clamping region between the lower part of the housing and the upper part of the inner housing.

[0017] In such a solution according to the invention which also requires independent protection, the diaphragm is clamped in a clamping zone between the lower housing part and the upper housing part of the inner housing. The diaphragm is here sealed, for example, between the lower housing part (one side) made of ceramic and the upper part of the inner housing preferably made of plastic (the other side).

[0018] According to a preferred embodiment of the invention, the materials of the lower housing part and the upper housing part of the inner housing are different and / or the upper housing part of the inner housing is made of plastic.

[0019] In order to be able to operate the sanitary valve according to the invention in a functionally reliable manner, every mechanism that allows the diaphragm to be placed on the valve seat of the main valve or lifted from the valve seat is suitable. However, according to an improved embodiment form of the invention, the sanitary valve has a pilot valve in its inner housing, by means of which the main valve can be controlled between an open position and a closed position, and the position of the diaphragm can be preset by the position of a valve tappet connected to a push-push mechanism, by means of which the valve tappet can be switched between a switching position corresponding to the open position of the sanitary valve and a switching position corresponding to the closed position of the sanitary valve. The preferred embodiment described here allows the sanitary valve according to the invention to be operated in a functionally reliable and stable manner with relatively little effort.

[0020] In order to reduce the risk of undesired leakage and in order to reduce the number of annular seals required on the sanitary valve according to the invention, it is advantageous if the free sleeve end region of the valve connection piece configured as the valve seat is arranged at a distance below the separation plane provided between the lower housing part and the upper housing part of the inner housing.

[0021] Additionally contributing to the simple operation and actuation of the sanitary valve according to the invention is that the inner housing projects out of the outer housing by means of a guiding section, in which guiding section of the inner housing a button in control and / or operative connection with the valve tappet is movably guided. By operating the button, the pilot valve in the inner housing can be operated, by means of which the main valve can be controlled and the main valve can be selectively or alternately moved into its closed position or open position.

[0022] In order to be able to convert a rotational movement acting on the guiding section into a relative torsion of the inner housing and the outer housing, it is advantageous if the guiding section of the inner housing is torsionally resistant and connected to the lower housing part and / or the upper housing part of the inner housing and is configured as a rotatable operating element for the relative torsion of the inner housing and the outer housing.

[0023] In order to be able to keep the pressure required for operating the sanitary valve according to the invention and applied to the push button as low as possible, it is advantageous to arrange the valve seat between the valve outlet and the at least one valve inlet, which valve seat can be closed by means of a diaphragm that encloses a pressure chamber which can be filled from the at least one valve inlet, such that the diaphragm closes the valve seat in the closed position when the pressure chamber is filled and releases the valve seat in the open position when the pressure chamber is unloaded.

[0024] Here, according to a preferred embodiment of the invention, it is proposed that the unloading opening leading to the at least one valve outlet can be closed on the diaphragm by means of a valve tappet. Description of the Drawings

[0067] In Figures 1 to 21 and Figures 22 to 40 hygienic valves 1, 201 are shown in two embodiments 1, 201. The hygienic valves 1, 201, which can for example be installed in the fitting body of a hygienic fitting not shown further, have an inner housing 2, 202, which is rotatably supported in an outer housing 3, 203. In the interior of the housing of the inner housing 2, 202, a main valve 4, 204 is provided, which has a movable diaphragm 5, 205, which can move between Figure 8 and 9 the closed position shown in FIGS. 27 or 27 and Figure 7 and 26 at least one open position shown in FIGS., in which the diaphragm 5, 205 seals against the valve seat 6, 206 of the main valve 4, 204, and in which the diaphragm 5, 205 is spaced apart from the valve seat 6, 206.

[0068] By means of the main valve 4, 204, the liquid outlet in the hygienic valves 1, 201 can be selectively or alternately opened or closed. The inner housing 2, 202, which is torsionally supported about a rotational axis L in the outer housing 3, 203, has a first valve opening 7, 207, which is connected in a liquid-guiding manner to a first valve opening 8, 208 in the outer housing 3, 203 to form the valve outlet of the hygienic valve 1, 201. The pair of first valve openings 7, 8; 207, 208 are arranged at least with their adjacent opening sections along the rotational axis L. The inner housing 2, 202 also has at least one second valve opening 9, 209, which is arranged externally with respect to the valve outlet of the hygienic valve 1, 201 and is assigned to at least one second valve opening 10, 11; 210 in the outer housing 3, 203 to form at least one valve inlet 12, 13; 212 of the hygienic valve 1, 201.

[0069] In order to regulate the volume flow of the liquid flowing in via at least one valve inlet 12, 13; 212 per unit time through the sanitary valve 1, 201 and / or in order to be able to mix liquids with different properties, such as hot water or cold water, the respectively mutually assigned second valve openings 9, 10, 11; 209, 210 can be brought into coincidence by relative torsion of the inner housing 2, 202 and the outer housing 3, 203, such that the net opening cross-section through which at least one valve inlet 12, 13; 212 is unobstructed by the coincidence of the respectively mutually assigned second valve openings 9, 10, 11; 209, 210 can be changed. The inner housings 2, 202 of the sanitary valves 1, 201 each have a basin-shaped lower housing part 14, 214 which is shown in detail in Figures 10 to 11 and Figures 30 to 33 On the inner side of the bottom of the basin of the lower housing part, valve nipples 15, 215 project, which connect the first valve openings 7, 207 forming the valve outlets of the inner housings 2, 202 to the valve seats 6, 206 formed by the free sleeve end regions of the valve nipples 15, 215. Here, the lower housing parts 14, 214 of the housings having the valve openings 7, 9; 207, 209 of the inner housings 2, 202 are liquid-tightly applied against the outer housing 3, 203 at least in the annular region of the bottom of the basin which is external to the valve openings 7, 9; 207, 209 and / or in a partial region of the outer peripheral edge of the lower housing parts 14, 214. Since the valve nipples 15, 215 project in the basin-shaped lower housing parts 14, 214 of the inner housings 2, 202 and form liquid chambers 16, 216 between themselves and the inner peripheral edge of the lower housing parts 14, 214, the liquid chambers can also be used as mixing chambers in the shut-off and mixing valves shown in Figures 1 to 21 In the shut-off and mixing valves shown in

[0070] With the main valves 4, 204 provided in the sanitary valves 1, 201 shown here, the water outlet can be moved between an open position and a closed position. In addition, by relative torsion of the inner housing 2, 202 and the outer housing 3, 203, the volume of water flowing out of the sanitary valve 1, 201 can also be regulated or the liquids flowing in from at least two inflow lines can be mixed in the lower housing parts 14, 214 of the inner housing 2, 202. The sanitary valves 1, 201 shown here also have the advantages of a compact structural form and a relatively short installation length. In Figures 1 to 21 The outer housings 3, 203 of the sanitary valves 1, 201 shown in 22 to 40 respectively have a disc-shaped or plate-shaped housing bottom 17, 217, and the lower housing parts 14, 214 of the inner housings 2, 202 are liquid-tightly and torsionally applied against the housing bottom at least by means of their external annular region and / or peripheral region. Here, the lower housing parts 14, 214 of the inner housings 2, 202 and the housing bottoms 17, 217 of the outer housings 3, 203 are made of ceramic.

[0071] from Figures 10 to 13 or Figures 14 to 19 (one party) and Figures 30 to 33 and Figures 34 to 37 It is clear from the comparison between (one party) and (the other party) that the first valve openings 7, 8; 207, 208 of the outer housings 3, 203 and the inner housings 2, 202 have at least in the regions adjacent to each other a circular and matching opening cross-section. In the sanitary valve 1 shown in Figures 1 to 21 and configured as a shut-off and mixing valve, a second valve opening 9 in the inner housing 2 is assigned to at least two second valve openings 10, 11 in the outer housing 3 such that by a relative torsion of the inner housing 2 and the outer housing 3 about the rotational axis L, the net opening cross-section between the second valve opening 9 in the inner housing 2 and at least one of the second valve openings 10 or 11 in the second valve openings 10, 11 provided in the outer housing 3 can be reduced and the net opening cross-section can be increased relative to at least one of the other second valve openings 11; 10 provided in the outer housing, and vice versa. Here, the second valve openings 10, 11 provided in the outer housing 3 and in particular in its housing bottom 17 can be connected to different liquid input devices, for example liquid input devices for hot water and cold water.

[0072] In Figures 1 to 21 the sanitary valve 1 shown in

[0073] In Figures 22 to 40 the sanitary valve 201 shown in

[0074] Figures 22 to 40 is configured as a shut-off and regulating valve, by means of which the amount of water flowing through per unit time can be regulated. For this purpose, the sanitary valve 201 has in its housing lower part 214 a first valve opening 207 which cooperates with only one first valve opening 208 in the housing bottom 217 of the outer housing 203 such that by a relative torsion of the inner housing 202 and the outer housing 203 the amount of water flowing through per unit time can be regulated.

[0074] The mixing or regulating function provided in the sanitary valves 1, 201 is separate from the closing function of the sanitary valves 1, 201. The sanitary valves 1, 201 have a pilot valve 19, 219 in their inner housing 2, 202, by means of which the main valve 4, 204 can be actuated between an open position and a closed position. Herein, the position of the diaphragm 5, 205 can be preset by the position of the valve tappet 20, 220, which is connected to a push-push mechanism 21, 221, by means of which the valve tappet 20, 220 can be switched between a switching position corresponding to the open position of the sanitary valve 1, 201 and a switching position corresponding to the closed position of the sanitary valve. The push-push mechanism 21, 221 can be configured as a rotation / locking mechanism or also as a ballpoint pen mechanism, and allows the valve tappet 20, 220 to be adjusted between the open position and the closed position of the main valve 4, 204 respectively by a simple manual pressing or key movement. By means of the push-push mechanism 21, 221, the valve tappet 20, 220 can be switched between the switching position corresponding to the open position of the main valve 4, 204 and the switching position corresponding to the closed position.

[0075] As is particularly clear from the longitudinal sectional view according to Figures 7 to 9 and Figures 28 to 29 the main valves 4, 204 of the sanitary valves 1, 201 have a movable diaphragm 5, 205, which is made of an elastic material and bears the valve body 23, 223 of the main valve 4, 204. The diaphragm 5, 205 can be actuated by means of the pilot valve 19, 219. For this purpose, the pilot valve 19, 219 has a longitudinally movable valve tappet 20, 220, the position of which presets the corresponding position of the valve body 23, 223 along its adjustment path and thus presets the corresponding position of the diaphragm 5, 205.

[0076] On the outside of the push-push mechanism 21, 221, a button 24, 224 is formed, by means of which the push-push mechanism 21, 221 can be switched between different switching positions and in particular between the open position and the closed position of the main valve 4, 204 by repeated pressing. The push-push mechanism 21, 221 is in operative or control connection with the valve tappet 20, 220. The push-push mechanism 21, 221 has at least two switching states corresponding to the open position and the closed position, and due to the operative connection, the valve tappet 20, 220 can be switched between these at least two switching states.

[0077] In Figure 8 and 9 or 29, a lower or external switching position is shown, in which the main valve 4, 204 of the sanitary valve 1, 201 is closed and thus in its closed position. In Figure 7 and 28Shows the upper or otherwise external switching position, in which the main valves 4, 204 are fully open and thus in their open position. The pilot valves 19, 219 have relief openings 25, 225, which are formed in the valve bodies 23, 223 and thus in the movable diaphragms 5, 205. If the relief openings 25, 225 are closed, a pressure is generated which presses the diaphragms 5, 205 together with the valve bodies 23, 223 into the valve seats 6, 206 of the main valves 4, 204. The main valves 4, 204 are then in their closed position.

[0078] If the relief openings 25, 225 are opened, the mentioned pressure decreases, so that the diaphragms 5, 205 together with the valve bodies 23, 223 move away from the valve seats 6, 206. The main valves 4, 204 are thus opened. Correspondingly, Figures 7 to 9 Figures 28 to 29 show different positions of the valve tappets 20, 220, which respectively form one of at least two switching positions of the main valves 4, 204 that can be preset by a push-push mechanism 21, 221.

[0079] The main valves 4, 204 have valve seats 6, 206, which can be sealedly closed with the valve bodies 23, 223 and the diaphragms 5, 205. The valve seats 6, 206 are arranged in the flow-through direction between the valve inlets 12, 13 of the sanitary valve 1 or the valve inlets 212 of the sanitary valve 201 and the valve outlets. Therefore, the main valves 4, 204 are used to separate the valve inlets 12, 13 or the valve inlets 212 and the valve outlets of the main valves 4, 204.

[0080] The diaphragms 5, 205 enclose pressure chambers 26, 226, which are filled from the valve inlets 12, 13; 212 via filling openings (not further visible here) in the diaphragms 5, 205. The filling openings are always open. Thus, it is achieved that the diaphragms 5, 205 together with the valve bodies 23, 223 arranged thereon close the valve seats 6, 206 in the closed position shown in Figures 27 and 28 when the pressure chambers 26, 226 are filled and release the valve seats 6, 206 in the open position shown in Figures 29 and 30 when the pressure chambers 26, 226 are relieved of load. Figure 8 and 29 Shows the closed position in which the valve seats 6, 206 are closed and in the open position shown in Figures 29 and 30 when the pressure chambers 26, 226 are relieved of load. Figure 7 and 9 or 28 release the valve seats 6, 206 in the open position shown in Figures 29 and 30.

[0081] As already mentioned above, the relief openings 25, 225 can be closed and released by means of the valve tappets 20, 220. Since the relief openings 25, 225 open into the valve outlet, opening the relief openings 25, 225 causes the pressure reduction already mentioned in the pressure chambers 26, 226, which in turn causes the opening of the main valves 4, 204. For this purpose, the relief openings 25, 225 are dimensioned to be larger than the filling openings mentioned above.

[0082] The valve tappets 20, 220 are coupled via control elements 27, 227 to the push-push mechanisms 21, 221 in order to assume the switching positions described. The control elements 27, 227 are introduced into the pressure chambers 26, 226 from the outside in a sealed manner. A compensation device is also formed in the functional connection between the pilot valves 19, 219 and the push-push mechanisms 21, 221, which allows the operation of the push-push mechanisms 21, 121 even when the pilot valves 19, 219 are closed and cannot be further moved relative to the valve seats 6, 206.

[0083] In the single-piece views according to Figure 20 、 21 and Figure 26 、 27 it can be seen that the main valves 4, 204 also have cleaning elements 28, 228, which are elastically flexurally formed and penetrate with their pin-shaped free ends 29, 229 through filling openings (not further visible here) in the diaphragms 5, 205 and keep the filling openings unobstructed. The cleaning elements 28, 228 are fixedly arranged in the inner housings 2, 202 by means of their fixed ends.

[0084] From Figures 10 to 13 it is clear that the second valve opening provided in the lower housing part of the inner housing 2 is configured as an arcuate slot. As is clear from Figures 15 to 19 the second valve openings 10, 11 in the outer housing 3 that are assigned to the second valve opening 9 provided in the lower housing part 14 of the inner housing 2 are also each configured as arcuate slots in the region facing the lower housing part 14, and the valve openings 10, 11 in the housing bottom 17 have shorter arc segments compared to the valve opening 9 in the lower housing part 14. By relative torsion of the inner housing 2 and the outer housing 3, it is now possible to reduce the net opening cross-section between the second valve opening 9 in the inner housing 2 and at least one of the valve openings 10 or 11 in the outer housing 3 and at the same time increase the net opening cross-section of the second valve opening 9 in the inner housing 2 relative to the other second valve opening 11 or 10 provided in the outer housing 3, and vice versa.

[0085] As is clear from Figures 38 to 40It is clear that the net opening cross-section of the valve inlet in the sanitary valve 201 can be increased or decreased as required depending on the rotational position of the inner housing 202 that can be twisted relative to the outer housing 203, so as to increase or decrease the flow-through capacity through the sanitary valve 201.

[0086] The inner housings 2, 202 of the sanitary valves 1, 201 project out of the outer housings 3, 203 by means of guide sections 30, 230. In these guide sections 30, 230 of the inner housings 2, 202, keys 24, 224 that are in control or functional connection with the valve tappets 20, 220 are movably guided. The guide sections 30, 230 of the inner housings 2, 202 are connected to their lower housing parts 14, 214 and are configured here as rotatable operating elements for twisting the outer housings 3, 203 and the inner housings 2, 202 relative to one another. Here, except for the valve inlet and the valve outlet and the guide sections 30, 230, the outer housings 3, 203 surround the inner housings 2, 202.

[0087] In Figures 1 to 21 In the sanitary valve 201 shown in

[0088] In accordance with Figure 20 and 21 as well as Figure 26 and 27In the single-piece perspective view, the housings 3, 203 of valves 1, 201 can be seen, and the sleeve-shaped upper housing parts 34, 234 thereof. The upper housing parts 34, 234 have central through openings 35, 235 for the guiding sections 30, 230 of the inner housings 2, 202. Below the guiding sections 30, 230, the buttons 24, 224 can be seen, and if necessary, a cover (not further shown here) is detachably, lockably or similarly put on the buttons. The rotary covers 36, 236 of the push-push mechanisms 21, 221 can be inserted into the sleeve-shaped buttons 24, 224, and the control elements 27, 227 of the valve tappets 20, 220 extend into the rotary covers 36, 236. Grooves are provided on the peripheries of the rod-shaped control elements 27, 227, and the clips 37, 237 can be inserted into the grooves. The clips connect the valve tappets 20, 220 and their control elements 27, 227 to the rotary covers 36, 236 in a non-lost but movable manner. The return elements 39, 239 configured as compression springs act on the rotary covers 36, 236 and the bushings 38, 238 pushed into them. The upper housing parts of the inner housings 2, 202 are formed in two parts here and have outer parts 40, 240 carrying the guiding sections 30, 230, and inner parts 41, 241 are inserted into the outer parts. The control elements 27, 227 of the valve tappets 20, 220 are guided in the central guiding openings in the inner parts 41, 241, and the control elements 27, 227 are sealed in the guiding openings by the sealing rings 42, 242. In the inner parts 41, 241, the valve tappets 20, 220 are pressed towards the diaphragms 5, 205 by means of the helical compression springs 43, 243. In order to enable the valve tappets 20, 220 to hermetically close the relief openings 25, 225 in the diaphragms 5, 205, the valve tappets have sealing caps 44, 244 at their tappet ends facing the diaphragms 5, 205. Inside the lower housing parts 14, 214, the cleaning elements 28, 228 configured as compression springs and their ends 29, 229 extending into the non-shown inflation openings in the diaphragms 5, 205 are shown. The outer parts 40, 240 of the inner housings 2, 202 have guiding sections 30, 230, and the guiding sections have profiles formed by longitudinal grooves on their cylindrical outer peripheries. If necessary, a sleeve-shaped cover (not further shown here) is put on the profiled guiding sections 30, 230. Inside the outer parts 3, 203, the valve bodies 23, 223 can be seen, and the valve bodies are connected to the central fastening openings of the diaphragms 5, 205 in a locking or similar manner.

[0089] As can be seen from according Figures 7 to 9 and Figures 28 to 29As can be seen in the longitudinal sectional view, the diaphragms 5, 205 are clamped between the lower housing portions 14, 214 of the inner housings 2, 202 and their inner portions 41, 241. The diaphragms 5, 205 seal the different-component parts 14, 41; 214, 241 of the sanitary valves 1, 201 from each other. Sealing rings 45, 46, 47; 245, 246 are provided on the outer sides of the sanitary valves 1, 201. The sealing rings seal the sanitary valves installed in the fitting body of the sanitary fitting in the region of the annular shoulders serving as insertion stops on the outer peripheral edge of the housing or in the region of the valve inlets 12, 13; 212. Anti-twist projections 48, 248 project from the housing bottoms 17; 217. The anti-twist projections engage into corresponding holes in the fitting body, and the sanitary valves 1, 201 are fixed on the guiding sections 30, 230 during rotation to prevent the sanitary valves 1, 201 from being inadvertently twisted themselves.
