<p>A fluid pressure regulator includes a cylinder (16) fixed within a housing cavity (12), a sealing disc (22) carried at the closed end of the cylinder (16), and a piston (24) displaceable within the cylinder (16), the interior of the cylinder (16) being vented to the atmosphere. The piston (24) is of larger cross-sectional area than the sealing disc (22) and has a stem (26) of smaller cross-sectional area than, and passing through, the sealing disc (22). The stem (26) carries a valve member (28) movable by the displacement of the piston (24), from a fully open position towards and away from a flow control opening (14) to control the flow therethrough to a housing outlet (10). <IMAGE></p> |
