  • the joint 90 is mounted on the one hand in a joint slide 96 and on the other hand in an elongated hole 88 in the stem 48 of the valve stem 46 that extends along a longitudinal axis 49 of the stem.
  • valve 200 also has a valve body 14 on a valve seat 12 and a cover space 34 arranged above the valve body 14, which is filled with pressurized water between two flushing processes via connecting grooves (not shown here).
  • the cover space 34 is in turn closed above the valve body 14 with a valve cover 8 which is screwed or screwed into a cover socket 25 of the valve housing 9.
  • the cover socket 25 or cover 8 is in turn provided with ventilation openings 80 which are connected to a ventilation channel 82, as has already been done for the pressurized water valve 10 in FIG Figures 2 to 9 was shown.
  • the further embodiment of the pressurized water valve 200 differs from the pressurized water valve 10 of FIG Figures 2 to 9 in that the valve body 14 is compact and therefore not hollow, and in that two actuating elements 210, 250 are provided, which open up a choice between two different amounts of flushing water.
  • the two are Actuating elements 210, 250 combined in an assembly 205.
  • Each actuating element 210, 250 has a flooding chamber 220, 260 which is fluidically connected to the cover chamber 34 of the pressure flush valve 200 via a connecting channel 292. On their side opposite the connecting channel 292 in terms of flow, the flooding chambers 220, 260 are connected in terms of flow to a water outlet 290.
  • Each actuating element 210, 250 also has a trigger 211, 251, which can be operated from the outside and extends into the connection between the respective flooding chamber 220, 260 and the water outlet 290, where it enables this fluidic connection to be closed and opened in the manner of a valve.
  • the water outlet 290 is connected to a sewer line, for example as shown in FIG Fig. 1 is marked with the reference number 2008. This connection can be implemented via a separate drain line (not shown).
  • the water outlet 290 can, for example, also be connected to the drain connection 22 or the valve connection 24 of the pressure flush valve 200 for discharging the water from the flooding chambers 220, 260.
  • the flooding chambers 220, 260 each have a regulating body 222, 262 which can be moved linearly in the respective flooding chamber 220, 260 in a manner similar to a piston.
  • Each flooding chamber 220, 260 is provided with grooves (not shown) on its inner wall analogous to the cover chamber 34 of FIG Pressurized water valve. It is also conceivable, however, that instead of the inner walls of the flooding chambers 220, 260, the regulating bodies 222, 262 are provided with grooves.
  • the associated flooding chamber 220, 260 is filled with pressurized water via the above-mentioned grooves, which water flows in via the cover chamber 34 and the connecting channel 292.
  • An adjusting screw 212, 252 is screwed into each flooding chamber 220, 260, which limits the stroke hl, h2 of the regulating body 222, 262 in the flooding chamber 220, 260, which ultimately also defines the passage gap S in the pressure flushing valve 200 and thus the flushing water volume of the pressurized water valve 200 is.
  • the triggers 211, 251 keep the water outlet 290 closed between two flushing processes.
  • the cover chamber 34, the connecting channel 292 and the flooding chambers 220, 260 are filled with pressurized water which is under a pressure Dl which (see description of the embodiment of FIG Figures 2 to 9 ) is greater than the water pressure D2 under the influence of the atmosphere. If, for example, the trigger 251 is now actuated, as shown in FIG Fig. 13 and 16 As is shown by way of example, the water flows out of the flooding chamber 260 via the water outlet 290. The pressure in the flooding chamber 260 on the side of the adjusting screw 252 decreases and falls to atmospheric pressure D2.
  • the pressurized water in the connecting line and the cover chamber 34 under pressure Dl pushes in and moves the regulating body 262 until it comes into abutment with the adjusting screw 252.
  • the pressure in the cover chamber 34 also decreases and the valve body 14 is raised by the pressure of the pressurized water in the inlet connection 20.
  • the flushing water flows through the gap S that forms above the valve seat 12 under pressure Dl from a pressurized water tank connected to the inlet port 20 into the drain port 22 and further into the toilet bowl.
  • valve port 24 has a larger diameter than the drain port.
  • the valve connector 24 surrounds the outflow connector 22, the outflow connector 22 protruding beyond the valve connector 24 in the outflow direction and wherein the valve connector 24 and the outflow connector 22 are preferably arranged concentrically.
  • This design of valve connector and outlet connector has been chosen because in this example the pressurized water tank 2004 merges directly into the inlet connector 20.
  • Reset devices in this case designed as reset springs - which are not shown here for the sake of a better overview - ensure that the regulating body 262 and the valve body 14 are returned to their original position.
  • cover chamber 34, connecting channel 292 and flooding chamber 260 are filled with water again via the connecting grooves in the area of the cover chamber 34 and the grooves in the flooding chamber 260 or in the control body 262 until the water there is under the same pressure D1 as in the inlet port 20 or the pressurized water tank 2004.
  • the actuating elements 210, 250 are designed with the capacity of their flooding chambers 220, 260 or the adjusting screws 212, 252 are screwed in such that, depending on which trigger 211, 251 is actuated, a different amount of water is made available for rinsing.
  • full flushing for example with 3 liters, is enabled because the stroke hl of the control body 222 in the flooding chamber 220 is greater than the stroke h2 of the control body 262 in the flooding chamber 260, so that the valve body 14 when the trigger is actuated 211 performs a full stroke from a to c ( Fig.
  • the alternative embodiment of the pressurized water valve 200 with the two actuating elements 210, 250 for different amounts of flushing water is shown in a compact design.
  • the two actuating elements 210, 250 are combined in a compact assembly 205 and directly connected to the valve cover 8 of the valve.
  • the assembly 205 can, so to speak, be connected to the valve cover 8 by means of a screw connection instead of the adjusting screw 28 ′, the screw connection containing the connection channel 292.
