A governor for fluid powered diaphragm pumps is shown and described. At least one pump member or oscillatory member moves in response to the varying pressures in the inner chambers of the diaphragm pump. Thus, each pump member or oscillatory member moves at the frequency at which the pump operates.

A governor for fluid powered diaphragm pumps is shown and described. At least one pump member or oscillatory member moves in response to the varying pressures in the inner chambers of the diaphragm pump. Thus, each pump member or oscillatory member moves at the frequency at which the pump operates. Each pump member pumps fluid through a hydraulic circuit. The fluid flowing through the hydraulic circuit moves a flow regulator disposed in the line that provides communication between the air or power fluid supply and the main air valve or main valve with a pump. In the event the pump operates too fast or at too high a frequency, the pump member or members will pump hydraulic fluid through the circuit at a sufficient flowrate so as to move the flow regulator to a position where it reduces the flow rate of power fluid to the main valve of the pump. In the event the pump is operating too slow or at too low a frequency, the flowrate of hydraulic fluid in the circuit will consequently be reduced and the flow regulator will be biased towards an open position thereby increasing the rate of flow of power fluid to the main valve of the pump. Manual control of the flowrate through the hydraulic circuit, and therefore manual control of the flow regulator, is also provided.
