3) Right Turning
Turning the steering wheel to the right rotates the valve spool and indexes the grooves in the spool with holes in the sleeve
so that oil from the pump flows through the spool and sleeve and enters the Gerotor gear pump . Since the Gerotor pump is
being turned clockwise , the oil flows through the valve body to the port “R”. From port “R” the pressurized oil flows to the
rod side of the power steering cylinder and causes the front wheels to turn right. The oil contained in the piston side of the
cylinder is forced out and returns to the control valve “L” port and is directed back to the reservoir through port “T”.
