Abstract:
A flow control valve for use with a downhole motor includes a housing with at least one port and a sleeve with at least one opening. The sleeve is movable within the housing to align and offset the ports and openings. A first biasing member associated with a first portion of the sleeve and a second biasing member associated with a second portion of the sleeve bias the sleeve in a first direction, while pressure applied to the sleeve due to fluid flow moves the sleeve in an opposing second direction. Movement of the sleeve in the second direction compresses the first and second biasing members, disengages the first portion of the sleeve from the first biasing member, and aligns the openings with the ports to permit transmission of the pressure through the openings and ports.
