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 auxiliary chamber communicates with the flow regulating chamber through a restricting orifice which function to dampen or attenuate diaphragm vibration caused by pressure pulses or transients which may occur in the fluid supply conduit. In one arrangement the auxiliary chamber is formed as part of the regulator housing. In other arrangements, the auxiliary chamber is formed as part of a separate fitting attached to the regulator flow regulating chamber inlet.
