Abstract:
A flow control valve comprising:a housing having an inlet end adapted for receiving a fluid flow, an outlet end adapted for outputting the fluid flow and a central portion there between; a displaceable timing cup residing within the central portion; a piston having a base, a top, and a stem there between, the stem having a passage from the base to the top; a biasing member disposed around the stem of the piston and adapted to bias the piston toward the inlet end in response to the outlet end receiving fluid flow, wherein the biasing member is substantially immediately compressed when flow begins, thereby enabling movement of the timing cup to be unaffected; and a regulator having a first portion with at least one inlet port adapted for outputting fluid flow passing through the central portion of the housing, a second portion, and a ridge separating the first portion from the second portion.
