ABSTRACT:
A diaphragm type flow regulator has an electrically operated bleed valve to control fluid signal pressure in a chamber on one side of the diaphragm. A valve member mounted on the opposite side of the diaphragm is moved, in response to the difference in pressure between the signal chamber and a flow regulating chamber, with respect to a valve seat for controlling flow of a compressible fluid between an inlet and outlet in the flow regulating chamber. An inertial mass is mounted for limited, resiliently opposed movement on the diaphragm, and serves to dampen diaphragm vibration caused by pressure pulses in the fluid supply conduit.
