Proportional bypass valve having variable area orifice control means

A proportional bypass valve having a valve spool positioned in a bore in the valve for controlling the flow of fluid between the inlet port and outlet port, the spool having an axial passage and being biased by a spring to a neutral position and responding to pilot flow for controlling the flow rate...

Beschreibung
Zusammenfassung:	A proportional bypass valve having a valve spool positioned in a bore in the valve for controlling the flow of fluid between the inlet port and outlet port, the spool having an axial passage and being biased by a spring to a neutral position and responding to pilot flow for controlling the flow rate between said inlet and outlet port and a variable area orifice operatively associated with said passage in said spool for controlling pilot flow rate and having a predetermined pressure drop for any finite position of the spool, the flow rate between the inlet port and outlet port being in proportion to the pilot flow rate as determined by the bias of said spring.
