ABSTRACT:
A fluid pressure regulator includes a cylinder fixed within a cavity, a sealing disc carried at the closed end of the cylinder, and a piston displaceable within the cylinder, the interior of the cylinder being vented to the atmosphere. The piston is of larger cross-sectional area than the sealing disc and has a stem of smaller cross-sectional area than, and passing through, the sealing disc. The stem carries a valve member movable by the displacement of the piston, from a fully open position towards and away from a flow control opening to control the flow therethrough to the housing outlet.
