Abstract (en)
[origin: CN109519246A] An oil control valve for a cam phaser of an internal combustion engine where the spool is positioned by an external actuator. The pressure enters the end of the oil control valve where the resultant pressure force is balanced by the differential area of the spool. The spool contains two plate check valves enabling cam torque recirculation of oil from A to B or B to A depending upon the spool position. In mid position, the spool lands block A and B to hold the cam phaser position. Three or five positions may be utilized.
