Hydraulic pressure control valve










Image Number 15 for United States Patent #5645107.

A hydraulic pressure control valve includes a cylindrical valve body and a valve spool coaxially fitted therein, each having oil grooves and lands alternately provided on and along the respective peripheral inside and outside surfaces, the opposing oil grooves and lands having throttles therebetween whose throttling extent, are changeable in accordance with a relative angular displacement between the valve body and the valve spool such that the flow of a working oil is concentrated in wider throttles. Thus noise due to cavitation is reduced.
