Abstract

A valve device for a sanitary valve contains two water supplies (2, 5; 22, 25) which are of substantially identical configuration and which lead in each case from an inlet to an outlet. A diaphragm valve is arranged within each water supply. The diaphragm valve is configured in such a way that it operates as a volume control valve. Combining of the quantity-controlled water flows can take place downstream of the two water supplies. There is a control device which moves a valve closing body of pilot valves (12, 14) of the two diaphragm valves. As a result, a mixing valve can be realized by virtue of the fact that, during the reduction of the distance between the valve closing body of the pilot valve of one diaphragm valve and an associated control hole of said diaphragm valve, the corresponding distance is enlarged at the same time in the other diaphragm valve.

Ventileinrichtung für ein Sanitärventil Valve device for a sanitary valve
Die Erfindung bezieht sich auf eine Ventileinrichtung für ein Sanitärventil mit als Men- genregul ierventile ausgebildeten Membranventilen . Membranventile sind Ventile, bei denen der Ventilschließkörper eine Membran aufweist, wobei vorliegend ein Membranventiltyp verwendet wird , der durch ein Pilotventil gesteuert wird . Durch Öffnen des Pilotventils öffnet sich das Membranventil unter dem Druck des strömenden Wassers, und zum Schließen des Membranventils ist ebenfalls nur der Aufwand zum Schl ießen des Pilotventils erforderl ich , da der eigentliche Schließvorgang dann wieder durch den Wasserdruck erfolgt. Daher haben so Membranventile den großen Vorteil , dass sie einen geringen Betätigungsaufwand benötigen . Aus diesem Grunde werden sie in der Regel bei elektrisch betätigten Ventilen angewendet. Übl icherweise werden diese Membranventile nur zum Ein- und Ausschalten verwendet. The invention relates to a valve device for a sanitary valve with diaphragm valves designed as mass regulator valves. Diaphragm valves are valves in which the valve closing body has a diaphragm, wherein in the present case a diaphragm valve type is used, which is controlled by a pilot valve. By opening the pilot valve, the diaphragm valve opens under the pressure of the flowing water, and to close the diaphragm valve is also only the effort to schl ießen the pilot valve erforderl I, since the actual closing process then again by the water pressure. Therefore, diaphragm valves have the great advantage that they require a low operating cost. For this reason, they are usually applied to electrically operated valves. Usually these diaphragm valves are only used for switching on and off.
Es ist bereits ein elektrisch betätigtes Membranventil bekannt, bei dem die Steuerboh- rung des Membranventils mith ilfe eines elektrischen Antriebs geöffnet und geschlossen werden kann . Der maximale Hub der Membran , d . h . die Größe der Öffnungsstellung , ist durch einen Anschlag begrenzt, der unabhäng ig von dem Ein- und Ausschalten des Ventils m ithilfe eines Werkzeugs, näml ich eines Schraubendrehers, in seiner Position verändert werden kan n (EP 0 253 948 B1 ). Der Erfindung liegt die Aufgabe zu Grunde, eine Ventileinrichtung der eingangs genannten Art zu schaffen , mit der sich die Temperatur des durch das Ventil geregelten Wasserstroms durch das Mischverhältnis zwischen warmem und kaltem Wasser m it sehr geringem Kraftaufwand verstellen lässt. An electrically operated diaphragm valve is already known in which the control bore of the diaphragm valve can be opened and closed by means of an electric drive. The maximum stroke of the membrane, d. H . the size of the open position is limited by a stop which can be changed independently of the switching on and off of the valve with the aid of a tool, namely a screwdriver, in its position (EP 0 253 948 B1). The invention is based on the object to provide a valve device of the type mentioned, with the temperature of the regulated by the valve water flow can be adjusted by the mixing ratio between hot and cold water with very little effort.
Zur Lösu ng dieser Aufgabe schlägt d ie Erfindung eine Ventileinrichtung mit den im An- spruch 1 genannten Merkmalen vor. Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen . To solve this problem, the invention proposes a valve device with the features mentioned in claim 1. Further developments of the invention are the subject of dependent claims.
Die Ventileinrichtung enthält eine Wasserführung , die von einem Kaltwassereinlass über ein Membranventil zu einem Auslass für kaltes Wasser führt. Sie enthält weiterhin eine zweite Wasserführung , die von einem Warmwassereinlass über ein Membranven- til zu einem Auslass für warmes Wasser führt. Beide Membranventile sind als Mengen- regulierventil ausgebildet. Dazu lässt sich der Steuerkörper eines zugehörigen Pilot- ventils nicht nur zwischen einer geschlossenen u nd einer vollständ ig geöffneten Position bewegen , sondern kann bel iebige Positionen zwischen den beiden Endpositionen ein nehmen . Die Membran folgt damit der Bewegung des Steuerkörpers. Auf diese Weise lässt sich ein bel iebiges Mischungsverhältnis zwischen dem warmen und dem kalten Wasser einstellen . The valve device includes a water guide, which leads from a cold water inlet via a diaphragm valve to a cold water outlet. It also contains a second water supply that leads from a hot water inlet via a diaphragm valve to a hot water outlet. Both diaphragm valves are designed as volume control valves. For this purpose, the control body of an associated pilot not only move between a closed and a fully open position, but can take beliebige positions between the two end positions. The membrane thus follows the movement of the control body. In this way, you can adjust a bel ble mixing ratio between the hot and the cold water.
Die Auslässe beider Membranventile mü nden in einem gemeinsamen Mischwasser- auslass. Dieser kann sich innerhalb oder außerhalb eines Ventil körpers der Ventileinrichtung befinden . The outlets of both diaphragm valves must be in a common mixing water outlet. This can be located inside or outside of a valve body of the valve device.
Zum Einstellen des Mischungsverhältnisses dient eine Steuereinrichtung für die Pilot- ventile, mit der das Mischungsverhältnis eingestellt werden kann . To set the mixing ratio is a control device for the pilot valves, with which the mixing ratio can be adjusted.
In Weiterbildung der Erfindung kann vorgesehen sein , dass für beide Membranventile ein gemeinsamer Ventilschließkörper vorhanden ist, der als Steuerkörper für die Pilotventile beider Membranventile dient. Er kann dabei insbesondere gegenläufig bewegbar sein , so dass er beim Öffnen des einen Pilotventils in Richtung auf die Schl ießung des jeweils anderen Pilotventils bewegt wird . Auf d iese Weise ist es m it einfachen M itteln möglich , die Änderung des Mischungsverhältnisses der beiden Wasserführungen durch einen Vorgang vorzunehmen . In development of the invention can be provided that a common valve closing body is provided for both diaphragm valves, which serves as a control body for the pilot valves of both diaphragm valves. In this case, it can in particular be movable in opposite directions, so that it is moved when opening the one pilot valve in the direction of the closure of the respective other pilot valve. In this way, it is possible with simple means to change the mixing ratio of the two water passages by one operation.
Es ist aber ebenfalls möglich und wird von der Erfindung vorgeschlagen , dass in alternativer Ausgestaltung der Erfindung die beiden Membranventile jeweils einen eigenen Ventilschl ießkörper bzw. Steuerkörper aufweisen , wobei die beiden Steuerkörper dan n vorzugsweise durch eine gemeinsame Steuereinrichtung gemeinsam bewegt werden kön nen . Die beiden Steuerkörper können dabei durch eine Einrichtung der Steuereinrichtung zusammengehalten u nd dadurch zusammen bewegt werden . However, it is also possible and is proposed by the invention that in an alternative embodiment of the invention, the two diaphragm valves each have their own Ventilschl ießkörper or control body, wherein the two control body dan NEN preferably be moved together by a common control device NEN. The two control bodies can be held together by a device of the control device and thereby moved together.
Insbesondere kann in Weiterbildung der Erfindung vorgesehen sein , dass die Steuer- einrichtung eine mechan ische Steuereinrichtung ist. Wegen des nur geringen zum Betätigen aufzuwendenden Drehmoments können auch sehr kleine bzw. schmale Griffe hierzu verwendet werden . In particular, it can be provided in a development of the invention that the control device is a mechanical control device. Because of the small amount of torque required for actuation, even very small or narrow handles can be used for this purpose.
In weiterer Ausgestaltung der Erfindung kann vorgesehen sein , dass die Bewegu ng des Steuerkörpers bzw. bei zwei Steuerkörpern beider Steuerkörper jeweils eine ge- radlinige Bewegung ist. Insbesondere kann in Weiterbildung der Erfindung vorgesehen sein , dass die beiden Membranventile symmetrisch zueinander angeord net sind , insbesondere dann , wenn sie, wie der Erfindung ebenfalls vorschlägt, identisch ausgebildet sind . In a further embodiment of the invention it can be provided that the movement of the control body or in the case of two control bodies of both control bodies is in each case a straight-line movement. In particular, it can be provided in a development of the invention that the two diaphragm valves are symmetrical to each other angeord net, especially if they, as the invention also suggests, are identical.
Beispielsweise kann eine verdrehbare Welle, die außerhalb des Gehäuses der Sani- tärarmatur mit einem Drehgriff versehen ist, mithilfe eines Exzenters oder eines Nockens an einem Steuerkörper oder gegebenenfalls an zwei Steuerkörpern zu deren Versch iebung angreifen . Eine solche Anordnung ist insbesondere dann von Vorteil , wen n d ie beiden Membranventile spiegelbildlich angeordnet sind und der Steuerkörper zwischen ihnen hin- und hergehend bewegbar gelagert ist. In nochmal iger Weiterbildu ng der Erfindung kann vorgesehen sein , dass die Steuereinrichtung so ausgebildet ist, dass sie beide Steuerkörper oder gegebenenfalls die beiden entgegengesetzten Enden eines mehrteiligen Steuerkörpers so bewegen kan n , dass ein Verschl ießen beider Steueröffnungen der Membranventile mögl ich ist. In diesem Fall kan n d ie Anordnung aus zwei wirkungsmäßig parallel geschalteten Membran- ventilen auch als Absperrventil dienen . For example, a rotatable shaft, which is provided outside of the housing of the sanitary faucet with a rotary handle, attack by means of an eccentric or a cam on a control body or possibly on two control bodies to the Versch shift. Such an arrangement is particularly advantageous if the two diaphragm valves are arranged mirror-inverted and the control body is mounted reciprocatingly movable between them. In a further development of the invention it can be provided that the control device is designed such that it can move both control bodies or optionally the two opposite ends of a multi-part control body such that a closure of both control openings of the diaphragm valves is possible. In this case, the arrangement of two diaphragm valves operatively connected in parallel can also serve as a shut-off valve.
Beispielsweise können zwei Teile eines Steuerkolbens, dessen beide Enden zum Verschließen der Pilotöffnung dienen , teleskopisch ineinander gefü hrt sein , so dass sie einerseits gemeinsam bewegt werden können , andererseits aber auch beide Teile in unterschiedliche Richtungen . Die eine Bewegung kön nte durch einen Exzenter bewirkt werden , während die andere Bewegung durch einen Keil bewirkt werden könnte. Es lässt sich auf diese Weise auch eine Ventileinrichtung schaffen , die sowohl zum Ein- und Ausschalten als auch zur Tem peraturregelu ng dienen kan n . Dies kann auch durch Bewegen eines einzigen Betätigungselements in unterschiedl iche Richtungen erfolgen . For example, two parts of a control piston, both ends of which serve to close the pilot opening, can be guided telescopically into one another so that they can be moved together on the one hand, but also on the other hand in different directions. One movement could be effected by one eccentric while the other movement could be effected by a wedge. It can be created in this way, a valve device that can be used both for switching on and off as well as Tem peraturregelu ng. This can also be done by moving a single actuator in different directions.
Die Bewegung des oder der Steuerkolben kann über Exzenter, über einen Keilschie- ber, über ein Zahnrad , ein Gewinde, einen Bowdenzug , über Spindel , Feingewinde, Hebel oder dergleichen bewirkt werden . The movement of the control piston or pistons can be effected via eccentrics, via a wedge slide, via a toothed wheel, a thread, a Bowden cable, via spindle, fine thread, lever or the like.
In noch mals weiterer Ausgestaltu ng der Erfindung kann vorgesehen sein , dass d ie Steuereinrichtung einen Temperaturfühler, insbesondere ein Deh nstoffelement, aufweist, also ein Element, das der Temperatur des Mischwassers ausgesetzt ist und in Abhängigkeit von der Temperatur des Mischwassers eine Bewegung durchführt, die dan n direkt oder indirekt auf den Steuerkolben einwirkt. Damit kan n dann ein Thermestatventil verwirklicht werden , das ebenfalls den Vorteil hat, dass es sich sehr leicht be- dienen lässt. In yet another embodiment of the invention may be provided that the control device has a temperature sensor, in particular a Deh nstoffelement, ie, an element which is exposed to the temperature of the mixed water and in response to the temperature of the mixed water performs a movement that dan n acts directly or indirectly on the control piston. Thus, a thermostatic valve can be realized, which also has the advantage that it is very easy to serve.
Insbesondere kann erfindungsgemäß vorgesehen sein , dass auf die Steuereinrichtung sowohl ein Dehnstoffelement als auch eine manuelle Verstellung einwirkt. Damit kan n dann eine Ventileinrichtung für ein Sanitärventil verwirklicht werden , bei dem manuell mit geringstem Kraftaufwand das Öffnen oder Schließen des Ventils u nd eine Mengenregul ierung durchgeführt wird , während die Temperatureinstellu ng durch ein Deh n- stoffelement erfolgt. In particular, it can be provided according to the invention that both an expansion element and a manual adjustment act on the control device. In this way, a valve device for a sanitary valve can then be realized in which the opening or closing of the valve and a quantity regulation are carried out manually with the least expenditure of force, while the temperature adjustment is effected by a dehens element.

FIG. 2 shows the view of the valve device of FIG. 1 from below in FIG. 1; 3 shows a perspective broken view of the valve device of Figure 1.
Die Figur 1 zeigt in einem gemeinsamen Körper 1 einer Sanitärarmatur eine Ventileinrichtung mit zwei Membranventilen . In Figur 1 ist ein Wassereinlass 2 für kaltes Wasser dargestellt, der zu einem ersten Membranventil 3 führt. Dieses Membranventil 3 weist einen ringförmigen Ventilsitz 4 auf, stromab von dem eine zugehörige Wasserführu ng zu einem Auslass 5 für kaltes Wasser führt. Diese Kaltwasserführung zu dem Auslass 5 ist in nerhalb des ringförmigen Ventilsitzes 4 ausgebildet. Außerhalb des ringförmigen Ventilsitzes 4 ist ein Ringraum 6 gebildet, der mit dem Einlass 2 in Verbindung steht. Auf dem Ventilsitz 4 liegt ein Ventilschl ießkörper 7 auf, der in seinem auf dem Ventilsitz 4 aufliegenden Bereich eine Auflage 8 aus elastomerem Material aufweist. An der radial gerichteten Außenseite ist der Ventilschließkörper 7 mit einer Membran 9 verbunden , die eine U-förmige Falte bildet. Der äußere Schenkel dieser Membran 9 ist mit dem Körper 1 der Sanitärarmatur fest und dicht verbunden . Die Membran 9 übernimmt die Abdichtung zwischen dem Ventilschl ießkörper 7 und dem Körper 1 der Sanitärarmatur. Auf der dem Ventilsitz 4 abgewandten Seite des Ventilschließkörpers 7 ist ein Druckraum 1 0 gebildet. Von dem stromauf des Membranventils angeordneten Ringraum 6 führt eine Ausgleichsbohrung 1 1 durch den Ventilkörper 7 hindurch und mü ndet auf der Rückseite des Ventilschl ießkörpers 7, also in dem Druckraum 1 0. FIG. 1 shows in a common body 1 of a sanitary fitting a valve device with two diaphragm valves. FIG. 1 shows a water inlet 2 for cold water, which leads to a first membrane valve 3. This diaphragm valve 3 has an annular valve seat 4, downstream of which an associated Wasserführu ng leads to an outlet 5 for cold water. This cold water supply to the outlet 5 is formed in within the annular valve seat 4. Outside the annular valve seat 4, an annular space 6 is formed, which is in communication with the inlet 2. On the valve seat 4 is a Ventilschl ießkörper 7, which has in its resting on the valve seat 4 area a support 8 made of elastomeric material. At the radially directed outside of the valve closing body 7 is connected to a membrane 9, which forms a U-shaped fold. The outer leg of this membrane 9 is firmly and tightly connected to the body 1 of the sanitary fitting. The membrane 9 takes over the seal between the Ventilschl ießkörper 7 and the body 1 of the sanitary fitting. On the side facing away from the valve seat 4 of the valve closing body 7, a pressure chamber 1 0 is formed. From the upstream of the diaphragm valve arranged annular space 6 performs a balancing bore 1 1 through the valve body 7 through and mü ndet on the back of Ventilschl ießkörpers 7, ie in the pressure chamber 1 0th
Die Auflage 8 aus elastomerem Material , die an der Vorderseite des Ventilschließkör- pers 7 angeord net ist, kann einstückiger Teil der Membran 9 sein . The support 8 made of elastomeric material, which is net angeord net on the front of Ventilschließkör- 7, may be integral part of the membrane 9.
Durch den Ventilschl ießkörper 7 hindurch, beispielsweise durch dessen Mitte, führt eine Steuerbohru ng 1 2 von dem Druckraum 1 0 in die Wasserfü hrung stromab des Membranventils. Through the valve closing body 7, for example through its center, a control bore 1 2 leads from the pressure chamber 10 into the water supply downstream of the diaphragm valve.
Auf der gegenüberl iegenden Seite des Körpers 1 der Sanitärarmatur ist ein spiegelbid- lieh aufgebautes zweites Membranventil angeord net, das in einer Warmwasserführu ng angeordnet ist, die von einem Einlass 22 für warmes Wasser zu einem Auslass 25 für warmes Wasser führt. On the opposite side of the body 1 of the sanitary fitting, a second diaphragm valve, constructed in mirror-inverted fashion, is arranged, which is arranged in a warm water supply, which leads from an inlet 22 for warm water to an outlet 25 for warm water.
In dem Körper 1 der Sanitärarmatur ist ein Steuerkörper 14 angeordnet, der l inear verschiebbar ist. Er ist mithilfe von Dichtungen in dem Körper 1 abgedichtet unterge- bracht. Seine beiden Enden weisen einen Überzug 1 5 ebenfalls aus elastomerem Material auf. Diese beiden Enden liegen einer jeweil igen Mündung der Steuerbohrungen 1 2 in den betreffenden Druckraum 1 0, 20 gegenüber. Damit bildet der Steuerkörper 14 zusammen mit der jeweil igen Steuerbohrung 1 2 je ein Pilotventil für die beiden Membranventile. In der dargestellten Position sind die in den jeweiligen Druckraum 1 0, 20 mündenden Steuerbohru ngen 1 2 geöffnet. Gelangt nu n Wasser durch den Einlass 20 bzw. 22 auf die Eintrittsseite des jeweil igen Membranventils, so tritt das Wasser durch die betreffende Ausgleichsbohrung 1 1 in den Druckraum 1 0, 20 ein . Aus dem jeweil igen Druckraum 1 0, 20 fließt das Wasser durch die geöffnete Steuerbohru ng 1 2 hindurch zu m Auslass. Da auf der stromab l iegenden Seite des jeweil igen Ventilschließkörpers 7 kein Druck liegt, hebt dadurch das einströmende Wasser den Ventilschl ießkörper 7 vom Ventilsitz 4 ab. Das Ventil öffnet sich . Wenn sowohl kaltes als auch warmes Wasser einströmt, werden beide Ventile geöffnet. Die Öffnungsbewegung geht so weit, bis die Mündung der jeweiligen Steuerbohru ng 1 2 so nah vor dem Ende des Steuerkörpers 14 positioniert ist, dass dort nur noch eine sehr geringe Menge Wasser durch die Steuerbohru ng 1 2 ausfließt. Der Steuerkörper 14 weist die Form einer Spindel auf mit mehreren umlaufenden Nuten . An den beiden Enden ist der erwähnte Überzug 1 5 aus elastomerem Material angebracht, der um das jeweilige Ende des Steuerkörpers 14 heru m geschnappt ist und in eine Nut unmittelbar hinter dem Ende eingreift. Der Überzug 1 5 greift dadurch noch in die Bohrung 1 2 ein , in welcher der Steuerkörper 14 linear verschiebbar gelagert ist, und trägt daher auch zur Abd ichtung bei. An den Überzug 1 5 folgend ist in einer weiteren Nut jeweils eine umlaufende Dichtung 1 6 angeordnet, die eine weitere Verbesserung der Dichtung darstellt. In der Mitte zwischen den beiden Enden enthält der Steuerkörper 14 eine umlaufende Nut mit konstanter Breite und senkrecht zur Längsachse und parallel zueinander verlaufenden Nutenflan ken . In the body 1 of the sanitary fitting, a control body 14 is arranged, which is l inear slidably. It is sealed in the body 1 by means of seals. Its two ends have a coating 1 5 also made of elastomeric material. These two ends are a respective mouth of the control bores 1 2 in the respective pressure chamber 1 0, 20 opposite. Thus, the control body 14 together with the respective control bore 1 2 each forms a pilot valve for the two diaphragm valves. In the illustrated position, the opening into the respective pressure chamber 1 0, 20 Steuerbohru ning 1 2 are open. If water passes through the inlet 20 or 22 to the inlet side of the respective membrane diaphragm, the water enters the pressure chamber 10, 20 through the respective balancing bore 11. From the respective pressure chamber 1 0, 20, the water flows through the open Steuererbohru ng 1 2 through to m outlet. Since there is no pressure on the downstream side of the respective valve closing body 7, the inflowing water lifts the valve closing body 7 away from the valve seat 4. The valve opens. When both cold and hot water enters, both valves are opened. The opening movement goes so far until the mouth of the respective Steuererbohru ng 1 2 is positioned so close to the end of the control body 14, that there is only a very small amount of water through the Steuerbohru ng 1 2 flows out. The control body 14 has the shape of a spindle with a plurality of circumferential grooves. At the two ends of the mentioned coating 1 5 is mounted made of elastomeric material, which is nipped around the respective end of the control body 14 and engages m m in a groove immediately behind the end. The cover 1 5 thereby still engages in the bore 1 2, in which the control body 14 is mounted linearly displaceable, and therefore also contributes to the sealing at Abd. Following the coating 1 5, a peripheral seal 1 6 is arranged in a further groove, which represents a further improvement of the seal. In the middle between the two ends of the control body 14 includes a circumferential groove with a constant width and perpendicular to the longitudinal axis and mutually parallel Nutenflan ken.
Etwa in der Mitte des Körpers 1 der Sanitärarmatur ist quer zu der Längsachse des Steuerkörpers 1 4 eine Welle 1 7 in dem Körper 1 drehbar gelagert, die an ihrem außerhalb des Körpers 1 angeordneten Ende eine Längsverzahnung 1 8 zum Anbringen eines Handgriffs aufweist. An ihrem in das Innere des Körpers 1 hineinragenden Ende enthält die Welle 1 7 einen exzentrisch angebrachten Exzenterzapfen 1 9, der in die Nut des Steuerkörpers 14 eingreift. Durch Verdrehen der Welle 1 7 mithilfe eines Griffs kann daher der Steuerkörper 14 in seiner eigenen Längsrichtu ng verschoben werden . Die Welle 1 7 bildet mit dem Exzenterzapfen 1 9 eine Steuereinrichtung gemeinsam für die beiden Pilotventile. Wird der Steuerkörper 14 beispielsweise aus der in Figur 1 dargestellten mittleren Position nach rechts verschoben , bis er die Steuerbohrung 1 2 des rechten Membranventils verschl ießt, so kann der durch die Ausgleichsöffnung 1 1 in den Druckraum 20 eindringende Wasserdruck durch die Steuerbohrung 1 2 nicht mehr abfließen . Da der Druck an der Vorderseite des Ventilschl ießkörpers 7 u nd im Druckrau m 1 0 bzw. 20 an der Rückseite des Ventilschließkörpers 7 gleich ist, aber die Fläche an der Rückseite größer ist, hält der Druck des anstehenden Wassers das Ventil geschlossen bzw. schl ießt es, wen n der Steuerkörper 14 aus einer zunächst geöffneten Position in d ie geschlossene Position bewegt wird . Approximately in the middle of the body 1 of the sanitary fitting is transverse to the longitudinal axis of the control body 1 4, a shaft 1 7 rotatably mounted in the body 1, which has at its outside of the body 1 arranged end of a spline 1 8 for attaching a handle. At its end projecting into the interior of the body 1, the shaft 1 7 contains an eccentrically mounted eccentric pin 1 9, which engages in the groove of the control body 14. By rotating the shaft 1 7 by means of a handle, therefore, the control body 14 can be moved in its own Längsrichtu ng. The shaft 1 7 forms with the eccentric pin 1 9 a control device together for the two pilot valves. If the control body 14, for example, moved from the middle position shown in Figure 1 to the right until he schliessen the control bore 1 2 of the right diaphragm valve, so the through the expansion opening 1 1 in the pressure chamber 20 penetrating water pressure through the control bore 1 2 no longer flow away . Since the pressure at the front of the Ventilschl ießkörpers 7 u nd in Druckrau m 1 0 or 20 at the back of the valve closing body 7 is the same, but the surface is larger at the back, the pressure of the upcoming water keeps the valve closed or schl it pokes, who n the control body 14 is moved from an initially open position in the closed position.
In der dargestellten Ausführungsform wird beim Schließen des rechten Ventils das lin- ke weiter geöffnet und umgekehrt. Daher wird mit dem dargestellten Ventil das Verhältnis zwischen dem warmen und dem kalten Wasser eingestellt, also eine Mischu ng zwischen den beiden Temperaturen . In the illustrated embodiment, the left is opened further when closing the right valve and vice versa. Therefore, with the illustrated valve, the ratio between the hot and the cold water is set, so a mixture between the two temperatures.
Die Figur 2 zeigt die beiden Einlässe für kaltes Wasser 2 und für warmes Wasser 22 sowie die beiden Auslässe 5 bzw. 25 für das kalte bzw. warme Wasser. Erst hinter diesen beiden Auslassöffnungen 5, 25 erfolgt eine Zusammenführung der beiden Wasserströmungen und damit eine Mischung. FIG. 2 shows the two inlets for cold water 2 and for warm water 22 and the two outlets 5 and 25 for the cold and warm water. Only behind these two outlet openings 5, 25 is a merging of the two water flows and thus a mixture.
Die perspektivische Ansicht der Figur 3 zeigt nochmals die Art, wie der Exzenterzapfen 19 in die Nut des Steuerkörpers 14 eingreift. The perspective view of Figure 3 shows again the way in which the eccentric pin 19 engages in the groove of the control body 14.
