Abstract
In a pressure compensated steering valve, the effect of an input steering signal is cancelled by connecting the spool valve actuator to the reservoir. A shiftable spool valve is acted upon by end cap actuators, which are in turn controlled by a hand pump that is operated by a steering wheel. The spool valve is provided with internal passageways which place the pressurized end cap actuator in restricted fluid communication with the reservoir in order to cancel the effect of the input steering signal at a predetermined rate.
