2. When the solenoid is on
When the solenoid (1) is energized, the solenoid's
pushrod presses the spool (2) down, connecting port P
to port A and cutting off port A and port T, so the oil from
port P flows to port A.
When port P pressure reaches a pressure at or
greater than the spring (3), the plunger (4) moves to the
right and pressure oil flows from port P to port PAC.
When the pressure at port P is low, the oil from port
PAC is cut off, preventing backflow.
