ABSTRACT:
A diaphragm pump includes a pump chamber, a pressure fluid chamber, a diaphragm partitioning the interior of the pump into the pump chamber and the pressure fluid chamber, a cylinder communicating with the pressure fluid chamber, and a plunger reciprocable within the cylinder. The pressure fluid chamber or the cylinder communicates with a pressure fluid reservoir via a pressure regulating valve adapted to open when the pressure in the pressure fluid chamber is too high, and a valve adapted to open before the pressure in the pressure fluid chamber is too low, and to close when the pressure is restored to a given pressure level.
