Definitions
- the invention relates to a drain valve for a cistern according to the preamble of claim 1.
- Drain valves for cisterns have long been known.
- drainage valves which enable partial flushing with, for example, three liters of rinsing water have proved to be useful.
- either a full flush or a partial flush can be selected.
- two buttons are provided for flushing. Pressing one key causes a partial flush and a full flush when the other key is pressed.
- a drain valve that allows such a two-stage flush is out of the EP 0 722 020 B became known.
- this drain valve the valve body is raised to initiate the flushing process.
- a float controls a lever which prematurely releases the valve body so that it falls onto the valve seat prior to emptying the flushing cistern.
- this drain valve has proven itself many times.
- the drain valve has the advantage that it can be built very compact. The actuating force as well as the actuating travel when opening and closing the valve but are relatively large.
- the drain valve has a main valve body, which can be lifted from its seat by actuating an auxiliary valve by means of an actuating device due to a negative water balance occurring in a relief chamber.
- a negative pressure which raises the main valve body in the manner of a piston.
- an auxiliary auxiliary valve is provided, which is at least to open briefly to flood the discharge chamber. When the discharge chamber floods, a positive water balance is formed, causing the main valve body to prematurely close.
- the auxiliary auxiliary valve is assigned to a partial emptying a floating body.
- the auxiliary valve has an auxiliary valve body, which is to move down to trigger the flushing. This is a spring tensioned.
- This drain valve consists of comparatively many individual parts and requires a comparatively large volume of construction, which is particularly disadvantageous in concealed cisterns.
- EP 1 270 831 is a drain valve has become known, which also has an auxiliary valve and allows a release with a comparatively small actuation force. Both the opening and closing of the auxiliary valve is float controlled. The closing of the valve is delayed, which is disadvantageous.
- the invention has for its object to provide a drain valve of the type mentioned, which allows partial flushing and can be opened and closed with the smallest possible operating force and small actuation travel and can still be built compact and with relatively small volume.
- the drain valve should also be reliable.
- auxiliary auxiliary valve with a corresponding second auxiliary valve body is not required.
- the auxiliary valve with which the discharge chamber is at least partially emptied and the second auxiliary valve, with which the discharge chamber is flooded, are operated with the same auxiliary valve body.
- the opening of the valve opening of the first auxiliary valve and the closing of the valve opening of the second auxiliary valve can be carried out with a comparatively short stroke movement of the auxiliary valve body and thus with a correspondingly short actuating travel. This allows a much simpler and more compact construction of the drain valve. Due to the small actuating force and the small actuating travel, the drain valve is particularly suitable for a motorized operation.
- a particularly compact design results when, according to a development of the invention, the valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve are arranged on the main valve body. This also allows the number of items to be significantly reduced.
- the auxiliary valve body is vertically movable between the valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve, wherein the two auxiliary valve openings are arranged one above the other, preferably directly above one another.
- the first auxiliary valve is opened by lifting the main valve body and closed with the same stroke, the valve opening of the second main valve body.
- the main valve body is held in its basic position by a first pawl down and that this pawl is pivoted at a Spülauslect so that it releases the main valve body.
- a second pawl is arranged on the auxiliary valve body, with which the auxiliary valve body is connected to the main valve body. This allows a particularly reliable opening of the valve opening of the first auxiliary valve.
- the second latch cooperates with a float, which releases the auxiliary valve body upon reaching a predetermined Spülementgives.
- valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve are arranged on the main valve body.
- FIG. 1 shows in sections a cistern 1, which may be formed as usual and has an actuating device, not shown here.
- the cistern 1 has at a bottom 11 a conventional outlet nozzle 12, in which a drain valve 10 is inserted.
- Rinse water 66 stored in the cistern 1 is according FIG. 2 Rinse water 66 stored.
- the volume of the rinse water 66 is, for example, with a full cistern 1, six or nine liters.
- the water surface 46 is shown with the cistern 1 filled.
- the drain valve 10 is used to empty the cistern 1, where it is opened, for example, to actuate a button, not shown here and rinse water flows through the outlet nozzle 12 in a toilet bowl, not shown here.
- the flushing takes place as mentioned, for example by pressing a button. Basically, however, a non-contact motor control is conceivable.
- the drain valve 10 has a valve housing 2, which has a valve opening 5. Over this valve opening 5 a plurality of side openings 15 are arranged in the valve housing 2, through which rinse water 66 can flow with open valve opening 5 in the outlet pipe 12 and thus in the toilet bowl.
- the valve opening 5 forms a main valve body 3 with a main valve V.
- the main valve body 3 has a valve plate 14 which in FIG. 1 rests on a valve seat 13.
- the main valve V is in the FIGS. 1 to 3 closed.
- the valve body 3 has at its periphery a piston ring 16 which bears against an inner side 17 of a discharge chamber 4 in a vertically displaceable sealing manner.
- the main valve body 3 seals with the sealing ring 16 the discharge chamber 4 down from. He forms a piston between the in FIG. 1 shown lower position and one in FIG. 4 shown upper position with the in FIG. 6 shown limited stroke H3 is vertically movable.
- an auxiliary valve body 7 is mounted, which in FIG. 1 rests on a valve seat 18 of a first auxiliary valve HV1.
- a second valve seat 21 of a second auxiliary valve HV2 is arranged above this valve seat 18.
- This second valve seat 21 is formed by a pipe 67, which is integrally formed on the main valve body 3 by webs not shown here and has an upper edge 34.
- the tube 67 is open at an upper edge 34 and has a channel 6, which forms the Ventilöfnung of the second auxiliary valve HV2 at a lower end.
- the auxiliary valve body 3 is thus the common valve body for the first auxiliary valve HV1 and the second auxiliary valve HV2.
- the auxiliary valve body 7 has a valve disk 19 which rests on a valve seat 18 when the auxiliary valve HV1 is closed.
- the first auxiliary valve HV1 is closed and the second auxiliary valve HV2 is opened.
- the auxiliary valve body 7 is between the in FIG. 1 shown lower position and the in FIG. 3 shown upper position with a comparatively short stroke movable. This stroke is much shorter than the stroke H3 of the main valve body 3.
- the force required to lift the auxiliary valve body 7 is comparatively small.
- the second auxiliary valve HV2 is closed, the first auxiliary valve HV1, however, open.
- the main valve body 3 has on an upper side 44 at least one control opening 20 which is open towards the relief chamber 4 and which connects the relief chamber 4 to an opening 68 of the first auxiliary valve HV1 when the first auxiliary valve HV1 is open.
- This opening 68 leads into the main valve opening 5.
- water present in the relief chamber 4 can flow out through the control opening 20 into the opening 68 and thus into the outlet connection 12.
- the pipe 67 of the main valve body 3 projects beyond the main valve V closed valve housing 2, as the FIG. 1 shows.
- This tube 67 of the auxiliary valve body 7 is mounted.
- This auxiliary valve body 7 also projects beyond an upper end Valve housing 2 and has an overflow channel 22.
- the auxiliary valve body 7 forms in this case an overflow pipe, which determines the maximum filling of the cistern 1.
- the overflow channel 22 can also be arranged in a manner known per se outside the drainage valve 10.
- the auxiliary valve body 7 is thus not necessarily an overflow pipe.
- a float 69 is mounted, which forms an air chamber 26 and a water chamber 27 in a housing 25. These two chambers 26 and 27 are separated from each other by a bottom wall 32.
- the air in the air chamber 26 causes a buoyancy force according to arrow 28 and the water in the water chamber 27 at a partial emptying of the cistern ( Fig. 5 ) a weight according to arrow 29.
- a rod 23 is fixed, which projects down into a chamber 70 of the valve housing 2.
- a stop cam 24 is formed, which allows a maximum stroke H1.
- the FIG. 1 shows the float 69 in the lower position. Starting from this position, the float 69 can be lifted with the stroke H1 by the buoyancy force of the air chamber 26.
- a cam 30 is mounted, with the float 69 according to FIG. 1 with empty or partially empty cistern 1 on a two-armed first pawl 8 loads.
- the pawl 8 is pivotally connected to the valve housing part 2 a with the valve housing 2 and surrounds the tube 67 in a semicircle.
- two cams 33 are mounted, which cooperate with the main valve body 3.
- the main valve body 3 has on its outside two opposite vertical ribs 71 and 71 '( Fig. 6 ), which have an upper edge 72 or 72 ', on which in each case a cam 33 according to FIG. 1 is applied.
- FIG. 6 the main valve body 3 has on its outside two opposite vertical ribs 71 and 71 '( Fig. 6 ), which have an upper edge 72 or 72 ', on which in each case a cam 33 according to FIG. 1 is applied.
- the main valve body 3 is locked in the closed position shown by the two cams 33.
- the main valve body 3 can thus not be raised.
- the illustrated position of the first pawl 8 is held in this position by the weight of the float 69.
- the float 69 is as shown in the raised to the highest position and thus the latch 8 relieved of the weight of the float 69.
- the float 69 drops down again and loads with the cam 30 on the first pawl eighth
- a second also two-armed in the directions of the double arrow 65 pivotable pawl 9 is mounted, which surrounds the auxiliary valve body 7 in a semicircular shape and is connected thereto via a rotary joint 38.
- a respective driver 40 or 62 is arranged, on which a pull rod 41 or 60 (FIG. Fig. 6 ) attacks.
- the drivers 40 and 62 each form a pin which engages in a slot 42 of the tie rod 41 and 60, respectively.
- the drawbar 41 and 60 can be raised with an actuating device, not shown here, for example with an actuating lever in the direction of arrow 43 and 63, respectively.
- a shoulder 36 is arranged, which rests with raised auxiliary valve body 7 at the edge 72 and 72 'of the rib 71 and 71' instead of the cam 33, as the FIG. 3 shows.
- Is pulled on the drawbar 41 and 60 so this exerts on the second pawl 9 a torque, which with respect to the rotary joint 38 in FIG. 1 counterclockwise acts.
- the first pawl 8 is rotated counterclockwise about the pivot 37 during lifting of the auxiliary valve body 7 and thus the two cams 33 are pushed away from the edge 72.
- the auxiliary valve body 7 is raised so that the main valve body 3 is locked to the auxiliary valve body 7.
- a further chamber 73 is arranged according to FIG. 7 an opening 75 which is closable with a slide 76.
- a float 50 is arranged, which is mounted pivotably about a pivot joint 53 on the valve housing 2.
- the float 50 is a so-called Kippschwimmer and has a lower air chamber 55 and an upper water chamber 58.
- the chambers 55 and 58 are separated by a bottom wall 57 from each other.
- the chamber 73 is in filled cistern according FIG. 2 filled with water.
- the air in the air chamber 55 causes a buoyant force according to arrow 56 and the water in the water chamber 58 at empty chamber 73 a weight according to the Arrow 59.
- a forwardly projecting nose 51 and an upwardly projecting stop cam 52 are arranged at the float 50.
- the stop cam 52 cooperates with the second pull rod 60.
- This pull rod 60 is provided for a full flush and can be raised in the direction of arrow 63.
- the second pull rod 60 has a slot 61 into which the catch 62 of the second pawl 9 engages. If the pull rod 60 is raised in the direction of the arrow 63, the pull rod 60 engages the driver 62 and thus pulls the main valve body 7 upwards.
- the pawl 8 rests simultaneously on the rib 71 and on the second opposing rib 71 '.
- the rib 71 ' also has an upper edge 72' on which the pawl 8 rests.
- the first pawl 8 and the second pawl 9 thus extend arcuately around the auxiliary valve body 7. In the FIG. 1 is the one side and in the FIG. 6 the other side visible.
- the tongue 74 formed on the lower end of the second pull rod 60 is raised at the same time. In the basic position, this tongue 74 is according FIG. 6 on the stop cam 52 and thus prevents tilting of the float 50 about the pivot 53.
- the tongue 74 is according to FIG. 7 raised above the stop cam 52 and thus the float 50 is free and can pivot about the pivot 53 in a clockwise direction due to said torque.
- the nose 51 engages with a recess 64 of the rib 71 '. This causes a locking of the raised main valve body 3.
- the float 50 remains in this position as long as there is water in the chamber 73 and thus said torque is applied.
- the outflow of water from the chamber 73 can with the in FIG. 7 shown slider 76 are regulated.
- This slider 76 is located in front of the opening 75 and can be moved in the directions of the double arrow 77. If the slider 76 is in the in FIG. 7 shown position, the opening 75 is closed. If the level of the rinse water 66 drops below the level of the opening 75, the water in the chamber 73 remains until the cistern 2 is substantially emptied. With the slide 76 raised, however, the chamber 73 empties relatively quickly, so that the chamber 73 is emptied before the cistern 1 is emptied. If the chamber 73 is emptied, the said torque is no longer present and the float 50 tilts due to its weight immediately in the FIG. 6 shown position.
- the main valve body 3 is thereby released and falls due to its own weight immediately on the valve seat 13, whereby the main valve V is closed.
- the auxiliary valve body 7 is unlocked prematurely and also falls due to its weight down and thus closes the first auxiliary valve HV1.
- the full amount can be set to six liters or nine liters. This is a default setting, which is usually not changed after the installation of the cistern 1.
- the cistern 1 is thus installed for a full flush with, for example, nine liters or for a full flush with six liters.
- FIG. 2 Before triggering a flush cistern 1 with flushing water 66 is according to FIG. 2 filled. Due to the buoyancy of the water, the float 69 is raised. The main valve body 3 is loaded in the closed position by the water 66. The discharge chamber 4 is also filled with water, which also rests on the main valve body 3.
- the pull rod 41 is raised in the direction of arrow 43.
- the comparatively small force for lifting the drawbar 41 can be done by hand or with a motor, not shown.
- the drawbar 41 of the auxiliary valve body 7 is raised and finally in accordance with the raised position FIG. 3 the first pawl 8 is pivoted by a pivoting movement of the second pawl 9.
- the auxiliary valve body 7 is thus locked with the main valve body 3 and at the same time the locking of the main valve body 3 is lifted to the valve housing 2.
- the first auxiliary valve HV1 is opened and immediately thereafter the second auxiliary valve HV2 is closed with the same stroke.
- first auxiliary valve HV1 If the first auxiliary valve HV1 is open, then flows according to FIG. 3 in the direction of arrow 47 water from the discharge chamber 4 down into the outlet pipe 12. This creates a differential pressure on the main valve body 3, the up in the in FIG. 4 shown position is driven. As a result, the main valve V is opened and the water 66 flows according to FIG. 4 through the openings 15 in the direction of the arrows 48 from the cistern 1 in the toilet bowl.
- the auxiliary valve body 7 When lifting the main valve body 3, the auxiliary valve body 7 is at the same time, since it is locked as mentioned with the main valve body 3 by the second pawl 9. Since the rinse water 66 flows out of the cistern 1, the water surface 46 correspondingly decreases. If this water surface 46 reaches the float 69, the buoyancy of the float 69 subsequently decreases and the latter sinks accordingly. Finally, the cam presses 31 on the second pawl 9 and pivots it in the clockwise direction in the FIG. 5 shown position. The cam 30 is now against the first pawl 8 and presses it against the ribs 71 and 71 '. The auxiliary valve body 7 is now unlocked and falls immediately due to its own weight on the valve seat 18.
- the first auxiliary valve HV1 is closed.
- rinse water 66 in the control port 20 and finally in the discharge chamber 4.
- This water rests on the main valve body 3, which thereby immediately falls down on the valve seat 13.
- the main valve V is closed.
- the cistern 1 is only partially emptied, since the water surface 46 has lowered until approximately in the area of the float 69. In the cistern 1 thus remain, for example, still six liters of rinse water.
- the main valve body 3 is located on the valve seat 13, so is the auxiliary valve body 7 in the in FIG. 2 shown lower position.
- this pawl 8 is again in the in FIG. 2 shown pivoted position in which the main valve body 3 is locked to the valve housing 2.
- the sinking of the water surface 46 is not one here shown per se conventional inlet valve open and thus rinse water flows into the cistern 1 and this is finally refilled until the water surface 46 is about the in FIG. 2 achieved level reached.
- the cistern 1 is thus back in the in FIG. 2 shown starting position and thus ready for further flushing.
- the second pull rod 60 is according to FIG. 6 raised in the direction of arrow 63.
- the purge is thus triggered as explained above, since in this case the main valve body 7 is raised and thus the first auxiliary valve HV1 is opened and the second auxiliary valve HV2 is closed.
- the float 50 is unlocked and this now tilts in FIG. 6 clockwise about the axis of the pivot 53. Is the main valve body 3 to the stroke H2 ( Fig. 6 ), the float 50 tilts further in the same direction of rotation and the nose 51 finally engages in the recess 64, as in FIG. 7 is shown.
- the main valve body 3 is now locked to the valve housing 2.
- the swimmer 69 which sinks after the rinsing release, closes the auxiliary valve HV1 as in the case of a partial rinse, but remains ineffective and can not interrupt the rinsing. If the slider 76 is raised and thus the opening 75 free, the float 50 is as explained above before a complete emptying of the cistern 1 back into the in FIG. 6 shown pivoted position and lifted the lock of the main valve body 3, thus interrupting the flushing.
- a full flush is also carried out, but only with six instead of, for example, nine liters of rinse water 66th ⁇ B> LIST OF REFERENCES ⁇ / b> 1 cistern 29 arrow 2 valve housing 30 cam 2a Valve housing part 31 cam 3 Main valve body 32 bottom wall 4 relief chamber 33 cam 5 Ventilöfnung 34 edge 6 Channel (valve opening) 35 poor 7 Auxiliary valve body 36 shoulder 8th first latch 37 swivel 9 second latch 38 swivel 0 drain valve 39 poor 1 Spülkastenboden 40 takeaway 12 outlet connection 41 pull bar 13 valve seat 42 Long hole 14 valve disc 43 arrow 15 opening 44 top 16 piston ring 45 opening 17 inside 46 water surface 18 valve seat 47 arrow 19 valve disc 48 arrow 20 control port 49 arrow 21 valve seat 50 swimmer 22 Kochlauflcanal 51 nose 23 Rod 52 stop cams 24 stop cams 53 swivel 25 casing 54 double arrow 26 air chamber 55 air chamber 27 water chamber 56 arrow 28 arrow 57 bottom wall 58 water chamber 72 edge
Description
Die Erfindung betrifft ein Ablaufventil fur einen Spülkasten nach dem Oberbegriff des Anspruchs 1.The invention relates to a drain valve for a cistern according to the preamble of
Ablaufventile für Spülkästen sind seit langem bekannt. Bewährt haben sich insbesondere Ablaufventile, welche eine Teilspülung mit beispielsweise drei Litern Spülwasser ermöglichen. Bei einem solchen Spülkasten kann wahlweise eine Vollspülung oder eine Teilspülung gewählt werden. In der Regel sind hierzu zwei Tasten für die Spülauslösung vorgesehen. Beim Drücken der einen Taste wird eine Teilspülung und beim Drücken der anderen Taste eine Vollspülung ausgelöst.Drain valves for cisterns have long been known. In particular, drainage valves which enable partial flushing with, for example, three liters of rinsing water have proved to be useful. In such a cistern, either a full flush or a partial flush can be selected. As a rule, two buttons are provided for flushing. Pressing one key causes a partial flush and a full flush when the other key is pressed.
Ein Ablaufventil, das eine solche Zweistufen-Spülung ermöglicht, ist aus der

Der Erfindung liegt die Aufgabe zugrunde, ein Ablaufventil der genannten Art zu schaffen, das eine Teilspülung ermöglicht und mit möglichst kleiner Betätigungskraft und kleinem Betätigungsweg geöffnet und geschlossen werden kann und das dennoch kompakt und mit vergleichsweise kleinem Volumen gebaut werden kann. Das Ablaufventil soll zudem funktionssicher sein.The invention has for its object to provide a drain valve of the type mentioned, which allows partial flushing and can be opened and closed with the smallest possible operating force and small actuation travel and can still be built compact and with relatively small volume. The drain valve should also be reliable.
Die Aufgabe ist bei einem gattungsgemässen Ablaufventil gemäss Anspruch 1 gelöst.The object is achieved in a generic drain valve according to
Beim erfindungsgemässen Ablaufventil ist ein separates Zusatz-Hilfsventil mit einem entsprechenden zweiten Hilfsventilkörper nicht erforderlich. Das Hilfsventil, mit dem die Entlastungskammer wenigstens teilweise entleert wird und das zweite Hilfsventil, mit dem die Entlastungskammer geflutet wird, werden mit demselben Hilfsventilkörper bedient. Mit der gleichen Belegung des Hilfsventilkörpers, mit dem die Ventilöffnung des ersten Hilfsventils freigegeben wird, wird auch die Ventilöffnung des zweiten Hilfsventils geschlossen. Das Öffnen der Ventilöffnung des ersten Hilfsventils und das Schliessen der Ventilöffnung des zweiten Hilfsventils kann mit einer vergleichsweise kurzen Hubbewegung des Hilfsventilkörpers und damit mit einem entsprechend kurzen Betätigungsweg erfolgen. Dies ermöglicht einen wesentlich einfacheren und kompakteren Aufbau des Ablaufventils. Aufgrund der kleinen Betätigungskraft und des kleinen Betätigungsweges eignet sich das Ablaufventil besonders für eine motorische Betätigung.When the drain valve according to the invention, a separate auxiliary auxiliary valve with a corresponding second auxiliary valve body is not required. The auxiliary valve with which the discharge chamber is at least partially emptied and the second auxiliary valve, with which the discharge chamber is flooded, are operated with the same auxiliary valve body. With the same occupancy of the auxiliary valve body with which the valve opening of the first auxiliary valve is released, and the valve opening of the second auxiliary valve is closed. The opening of the valve opening of the first auxiliary valve and the closing of the valve opening of the second auxiliary valve can be carried out with a comparatively short stroke movement of the auxiliary valve body and thus with a correspondingly short actuating travel. This allows a much simpler and more compact construction of the drain valve. Due to the small actuating force and the small actuating travel, the drain valve is particularly suitable for a motorized operation.
Ein besonders kompakter Aufbau ergibt sich dann, wenn gemäss einer Weiterbildung der Erfindung die Ventilöfnung des ersten Hilfsventils und die Ventilöffnung des zweiten Hilfsventils am Hauptventilkörper angeordnet sind. Damit kann zudem die Anzahl der Einzelteile wesentlich verkleinert werden.A particularly compact design results when, according to a development of the invention, the valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve are arranged on the main valve body. This also allows the number of items to be significantly reduced.
Ein noch einfacherer Aufbau ergibt sich dann, wenn gemäss der Erfindung der Hilfsventilkörper zwischen der Ventilöffnung des ersten Hilfsventils und der Ventilöffnung des zweiten Hilfsventils vertikal bewegbar ist, wobei die beiden Hilfsventilöffnungen übereinander, vorzugsweise unmittelbar übereinander angeordnet sind. Durch eine vergleichsweise kleine vertikale Bewegung des Hauptventilkörpers kann das erste Hilfsventil geöffnet und das zweite Hilfsventil geschlossen werden. Dadurch ist ein besonders kurzer Betätigungsweg möglich.An even simpler structure results when, according to the invention, the auxiliary valve body is vertically movable between the valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve, wherein the two auxiliary valve openings are arranged one above the other, preferably directly above one another. By a comparatively small vertical movement of the main valve body, the first auxiliary valve can be opened and the second auxiliary valve can be closed. As a result, a particularly short actuation path is possible.
Vorzugsweise wird das erste Hilfsventil durch Anheben des Hauptventilkörpers geöffnet und mit dem gleichen Hub die Ventilöffnung des zweiten Hauptventilkörpers geschlossen.Preferably, the first auxiliary valve is opened by lifting the main valve body and closed with the same stroke, the valve opening of the second main valve body.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der Hauptventilkörper in seiner Grundstellung von einer ersten Klinke nach unten gehalten ist und dass diese Klinke bei einer Spülauslösung so verschwenkt wird, dass sie den Hauptventilkörper freigibt.According to a development of the invention, it is provided that the main valve body is held in its basic position by a first pawl down and that this pawl is pivoted at a Spülauslösung so that it releases the main valve body.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass am Hilfsventilkörper eine zweite Klinke angeordnet ist, mit welcher der Hilfsventilkörper mit dem Hauptventilkörper verbunden wird. Dies ermöglicht ein besonders funktionssicheres Öffnen der Ventilöffnung des ersten Hilfsventils.According to a development of the invention it is provided that a second pawl is arranged on the auxiliary valve body, with which the auxiliary valve body is connected to the main valve body. This allows a particularly reliable opening of the valve opening of the first auxiliary valve.
Nach einer Weiterbildung der Erfindung ist zur Auslösung der Teilspülung vorgesehen, dass die zweite Klinke mit einem Schwimmer zusammenarbeitet, welcher den Hilfsventilkörper beim Erreichen eines vorbestimmten Spülwasserniveaus freigibt.According to a development of the invention, it is provided for triggering the partial flush that the second latch cooperates with a float, which releases the auxiliary valve body upon reaching a predetermined Spülwasserniveaus.
Eine besonders kostengünstige Herstellung und ein kompakter Aufbau ergibt sich dann, wenn gemäss einer Weiterbildung der Erfindung die Ventilöffnung des ersten Hilfsventils und die Ventilöffnung des zweiten Hilfsventils am Hauptventilkörper angeordnet sind.A particularly cost-effective production and a compact construction results when, according to a development of the invention, the valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve are arranged on the main valve body.
