ABSTRACT:
The piston membrane pump has a feed chamber for the fluid to be pumped and a piston working chamber, a membrane hermetically separating the feed chamber and the piston working chamber and a piston oscillating back and forth in the piston working chamber. The piston working chamber is completely filled with a hydraulic medium from a supply container in operation so that the membrane oscillates with the piston. A refill valve which connects the piston working chamber with the supply container cooperates with a spring-loaded sliding control element and a moving force-transmitting element displaceable against it so as to open the valve. So that the pump can operate at higher pressures and temperatures a metal membrane is used, the force-transmitting element is a resilient platelike piece acting against the spring-loaded sliding control element and the membrane has no contact surfaces in the feed chamber on its feed chamber side.
