Definitions

  • the invention relates to a piston diaphragm pump with a diaphragm separating the delivery and the piston working space, which is actuated via the hydraulic medium completely filling the piston working space by a piston oscillating back and forth in this space, and with a reservoir for the hydraulic medium, which is provided with a refill valve is in communication with the piston working space, and a spring plate for the diaphragm, which is arranged displaceably under spring pressure, a refill valve opening in the direction towards the storage container being provided between the reservoir for the hydraulic medium and the piston working space.
  • the object of the invention while avoiding the disadvantages shown, is to design the piston diaphragm pump of the type mentioned at the outset in such a way that even with increasing size, a minimum of masses to be accelerated is required, while at the same time lower internal pressure losses should occur.
  • the support plate in the piston work space is arranged freely movable and tiltable within limits, in the pump housing a separate from the support plate, directed towards the radially outer region of the control plunger between a protruding position in the direction of the support plate and one on the other hand, axially pushed back release position is guided displaceably, a spring pressing it permanently into its locking position against the control tappet and the support plate in the locked position of the control tappet can be pressed against the spring-loaded control tappet with a radially outer region in order to press it against the spring in its release position move.
  • the support plate is now freely movable and can move or tilt against the pressure of the spring acting on the control tappet and thus trigger the refill.
  • a tumbler arranged between the control plunger and the valve is provided for locking or releasing the refill valve.
  • the control plunger expediently has a conical circumferential rotation along which the tumbler slides during the displacement of the control plunger.
  • the control plunger When actuated, the control plunger preferably abuts the support plate in its peripheral area.
  • a plurality of springs are preferably provided which engage on the circumference of the support plate.
  • the piston diaphragm pump shown has a displacement piston 1, which is oscillated back and forth in a piston working space 2 completely filled with hydraulic medium.
  • the membrane 4 arranged between the delivery chamber 3 and the piston working chamber 2 thereby executes a membrane stroke corresponding to the piston stroke volume.
  • the liquid to be pumped flows into the delivery chamber 3 via the suction valve 5 and is expelled via the pressure valve 6 during the pressure stroke.
  • a support plate 7 which, although freely movable, has a security against falling out in the direction of the membrane 4.
  • a plurality of springs 8a which are able to exert pressure on the support plate 7 in the direction against the membrane 4, act on the circumference of the support plate 7.
  • a control tappet 13 also acts, which is provided with a conical recess 13a.
  • the control plunger 13 is under the pressure of a spring 8 with direction of action against the support plate 7.
  • a tumbler 9 engages essentially perpendicularly thereto, which is connected to the closing body 10 of the valve 12 at the opposite end.
  • the length of the tumbler 9 is dimensioned such that the valve 12 is held in its closed position when it contacts the outer region of the circumferential rotation 13a of the control plunger 13. so that no hydraulic medium can flow into the piston working space from the reservoir 11. This is the normal position of the arrangement.
  • the diaphragm 4 reaches the support plate 7 and moves it against the pressure of the springs 8a in the direction of the piston working chamber against the spring-loaded Control plunger 13.
  • the control plunger 13 now resting on the support plate 7 moves in a forced manner against the spring force 8 in the same direction, so that the tumbler 9 slides on the conical circumferential recess 13a of the control plunger 13.
  • the closing body 10 of the refill valve 12 is released.
  • the refill valve 12 opens as a result of the negative pressure prevailing in the piston work chamber and allows hydraulic medium to flow into the piston work chamber from the reservoir 11.
  • the membrane 4 and the support plate 7 move under the pressure of the springs 8 and 8a in the direction of the front space 3.
  • the control plunger 13 is held in engagement with the support plate 7 by the pressure of the spring 8 and accordingly carries out the same movement .
  • the tumbler slides upwards along the conical circumferential recess 13a until it is supported again by the outer circumferential region of the control plunger 13. This in turn locks the closing body 10 in the closed position of the valve 12.
  • the spring shown on the valve 12 only serves to prevent the closing body 10 from falling, but without exerting any significant closing force on the valve.
  • a piston diaphragm pump was thus created which advantageously overcomes the disadvantages mentioned at the outset.
