ABSTRACT:
A fluid pressure regulator is described including a movable regulator member and means biassing same to its fully-open position, the regulator member being exposed to the outlet pressure for moving same in the opposite direction and including a pressure-sensor surface portion which, when the regulator member is in its fully-open position, engages an inner face of the housing such as to reduce the effective area of the pressure-sensor surface. The regulator member is thus retained in its fully-open position by the biassing means until the actual outlet pressure exceeds the regulated value by a preselected pressure differential, at which time the regulator member is moved by the outlet pressure away from its fully-open position, thereby making effective its complete pressure-sensor surface to thereafter regulate the outlet pressure.
