ABSTRACT:
A pressure regulator comprising a housing having an inlet connectable to a source of fluid at inlet pressure, an outlet, and a flow passage extending between the inlet and the outlet. A valve seat is mounted on the housing and in the flow passage. A valve element is mounted in the flow passage for movement between a closed position in which the valve element engages the valve seat to block flow through the flow passage and an open position in which the valve element does not block flow through the flow passage. Fluid downstream of the valve seat is at regulated pressure. The valve element is spring biased toward an open position. The valve element is pressure responsive and has a first pressure responsive area at least a portion of which is exposed to inlet pressure and a second pressure responsive area which is exposed to regulated pressure. The first area is smaller than the second area. With this arrangement, the fluid at inlet pressure and the spring urge the valve element toward the open position and the fluid at regulated pressure urges the valve element toward the closed position.
