  • the invention relates to a control for a suction and / or actuatable with negative pressure Water valve intended for a vacuum sewage system, especially intended for a vacuum-operated sanitary facility such as a toilet, urinal or sink, comprising a arranged in a housing and displaceable in this against a force Actuating element such as a control button, via which a first vacuum from a vacuum source comprehensive valve plate and piston for actuating the suction and / or water valve first valve can be actuated.
  • Corresponding control arrangements are, for example, in vacuum toilets in ships or Trains used.
  • Control button and the valve arrangement, via the vacuum to the suction or Water valve is passed are arranged in separate housings, so that additional Control lines are required.
  • Another disadvantage is that even if for one Suction process is not sufficient vacuum, a suction process is triggered that may cause the system to malfunction.
  • the suction or Water valve is continuously under pressure when the actuating element such as - button is constantly pressed, for example by a malfunction or operation.
  • the present invention is based on the problem of controlling the input mentioned type in particular intended for vacuum operated sanitary facilities To provide, which is extremely compact, while also ensuring should that if the actuator is operated incorrectly, negative pressure on the Suction or water valve is present. Furthermore, a suction process should only be triggered can, if the required negative pressure prevails. After all, in particular when used for water closets the possibility is given to the extent desired Keep the water valve open longer than the suction valve.
  • the problem is essentially solved in that the valve piston of the first valve by means of a first of a second chamber in the housing separating membrane is adjustable that the first via the first valve with the suction and / or Water valve connectable chamber is connected to the vacuum source that the second chamber after adjusting the actuator against the force in the Housing in and after moving the actuator back to its original position can be acted upon by atmospheric pressure and that on the membrane in the direction of the second Chamber acts a spring element, the membrane opposing the spring element force caused to open the first valve is adjustable when the first chamber from the pressure acting on the membrane less than from the second Chamber out of pressure acting on the membrane.
  • the teaching of the invention ensures that only when the actuator moved out of its starting position and then returned to it, Vacuum can get to the suction or water valve, due to the Membrane-separated chambers only then the first to the suction or Water valve negative pressure conductive valve is adjusted when in the first and the second Chamber pressure conditions prevail, which means a change of the membrane and thus the first Allow valve; the vacuum in the first chamber is not sufficient, around the membrane against the force caused by the spring element from its first the first valve closing position to its second position opening the first valve adjust, with atmospheric pressure prevailing in the second chamber, the first remains Valve closed, so that a suction process is not initiated as a result can.
  • the actuating element i.e. whose button by for example Jamming remains in a depressed position, since in this case the actuating element no connection between the atmospheric pressure and the second chamber can be manufactured.
  • the actuating element has a control piston is assigned, via which the second chamber can be sealed from the atmosphere, that when adjusting the actuator against the force into the housing Control piston in its closing the second chamber from the atmosphere Position remains and that the actuator when moving back to its original position takes the control piston, which in turn connects between the second Chamber and the atmosphere releases.
  • the actuating element must be removed from its initial position and then get back into this to open up the possibility that the first one is the negative pressure to the suction bwz.
  • Water valve releasing valve can be operated.
  • control piston is coupled to the membrane in such a way that moving the diaphragm from its first position closing the first valve to its second position the valve opens the diaphragm the control piston in its the Connection between the atmosphere and the second chamber closing position takes along.
  • a negative pressure can build up in the second chamber are, since preferably a connection between the valve piston of the first valve the first and second chamber, which is noticeably effective when the connection between the second chamber and atmospheric pressure is prevented.
  • control piston should be replaced by a second one Be surrounded by the spring element, which on the actuator such as control button acting force is caused.
  • a limiter on the membrane and / or the valve piston of the first valve acts that a change in position causing the first valve to change Membrane when vacuum is used to convey waste water through the suction valve he follows.
  • a magnet can act in particular on the membrane, the membrane a metal plate in the middle and atmospheric pressure in the second Chamber of the magnet itself is arranged. A limitation by the magnet is over the metal plate adjustable.
  • the teaching according to the invention enables an extremely compact construction of the control. since actuator with control piston, the first and second separated by the membrane Chamber and the first valve can be arranged together in a cylindrical housing can, preferably on the side facing away from the actuating element (rear) connections for the vacuum and the suction and / or water valve, wherein The control piston and valve piston should run coaxially along the central axis of the housing.
  • the control arrangement includes one in a wall 12 recessed cylindrical housing 14 with the above frustoconical or mushroom-shaped Section 16, in which an operating button 18 in the direction of the longitudinal axis of the housing 14 is adjustable.
  • the button 18 is coaxial with the longitudinal axis of the housing 14 extending control piston 20 in the manner described below in operative connection.
  • the Control piston 20 itself is surrounded by a coil spring 22, via which the required Force on the button 18 is caused out of the housing 14.
  • the control piston 20 has annular recesses spaced apart from one another in the axial direction 24, 26 on, depending on the position of the button 18 with, for example, three Interacting balls or a retaining ring 28 cooperate, the or the circumferential from to Example are or is surrounded by an O-ring 30 so that the balls or the retaining ring 28 show the effort or shows to engage in the locking recesses 24, 26.
  • the knob 18 has a Recess 31 in which - also depending on the position of the button 18 and of the locking ring 28 - either the control piston 20 protrudes or according to FIG. 1 runs outside or largely outside of this.
  • the actuating button 18 is also a cylindrical receptacle or chamber 32 in assigned to the housing 14 into which the control button 18 can be pressed. Acts a force from the outside on the control button 18, so the locking ring 28 or the locking balls pressed out of the upper groove 24 to in the lower groove 26 with further pushing in the control button 18 to engage.
  • the control piston 20 is not moved. Will the Control button 18 released, so can be caused by the coil spring 22 Force the control button 18 to be pressed outwards. Since the locking ring 28 with the Control button 18 is operatively connected, the control piston 20 is consequently pulled.
  • a connection 34 between the control button 18 receiving Receptacle 32 and a chamber 36, referred to as the second chamber, in the housing 14 are produced, which is otherwise blocked by the control piston 20, by a seal 38 which the connection 34 formed as a bore in the bottom 40 of the receptacle 32 closes. Consequently, the control piston 20 with the seal 38 so far Function of a valve.

  • the valve piston 50 is surrounded by a coil spring 54, which on the bottom surface 56 of the first chamber 44 or in the exemplary embodiment on a Support plate like metal plate 58, which extends centrally from the membrane 46.
  • the valve piston 50 also has a bore which connects the first chamber 44 with the connects second chamber 36.
  • a driver 62 starts from the central region of the membrane 46, and the a protruding portion 64 of the spool 20 in the manner described below can work together.
  • a connection 66 extends from the bottom area of the first chamber 44 and leads to a vacuum source leads. Center of the bottom surface 56 and the valve plate 68 of the first valve 52 closable is an opening 70, which leads to a connection 72, which in turn leads to a suction valve 74 and a water valve 76.
  • connection 72 goes through a chamber 78 in the bottom 80 of the housing 14 in the through first valve 52 closable opening 70.
  • the chamber 78 has one Opening 82, which communicates with the atmosphere and depending on the Position of the first valve 52 is open or closed by the valve plate 68.
  • connection can also be designed differently.
  • the Indian the control button 18 possibly receiving chamber 32 prevailing atmospheric pressure can not act on the second chamber 36, since the connection 34 through the Control piston 20, namely the seal 38 is closed.
  • the control button 18 is pressed into the housing 14, the connection remains 34 closed between the receptacle 32 and the second chamber 36.
  • Opening 70 in the bottom of first chamber 44 opens and connects to the atmosphere closed via the opening 82 in the chamber 78 by means of the valve plate 68. Consequently negative pressure can develop via the connection 72 to the suction and water valve 74, 76 reproduce so that they can be opened to suck off waste water and on the other hand refill water.
  • the membrane 46 and thus the valve 52 can be changed abruptly by that the metallic plate via a magnet 88 running in the second chamber 36 58 of the membrane 46 is held and is only released abruptly when in the a sufficient negative pressure prevails in the first chamber 44.
