ABSTRACT:
A valve system in a power steering system is disclosed. It includes a spool valve which is slidably located in a valve bore for by-passing an excess fluid at high vehicular speed in response to the pressure differential across an orifice. A control rod is slidably located in the spool valve and has at the end a metering portion for maintaining a limited flow volume when the spool valve is moved to close a by-pass port with the increase of a working pressure in the power steering system.
