A flow control valve having a piston and valve element connected together by a portion of a spring also connected to a pressure relief mechanism. Also disclosed is an alternative embodiment featuring a passage delivering metered flow from an input passage to a low pressure end of a piston and then through a pressure sensing means from the low pressure chamber to an output passage. A valving sub-assembly is movable to substantially suppress the flow rate ripple by bypassing a dominant portion of the flow rate ripple. |
