Title: Flow control valve assembly

Abstract: A flow control valve assembly for controlling the flow of a working fluid which has a housing that defines a valve chamber therein, an inlet port to the valve chamber and an outlet port from the valve chamber, a valve body which is movably carried in the chamber between a closed position that blocks the outlet port from communication with the inlet port and an open position so that the inlet port is in communication with the outlet port to allow the working fluid to be forced through the valve chamber, and a valve control means responsive to the velocity of the working fluid flowing through the valve chamber or responsive to the pressure differential across the valve body to operate the valve assembly by moving the valve body between the open position and the closed position.
