Abstract:
A solenoid operated diverter valve comprising:a valve body having a first inlet, a second inlet, a first outlet and a second outlet;a first passageway connecting the first inlet and first outlet to the second inlet;a solenoid valve disposed in a second passageway between the second inlet and the second outlet, the solenoid valve having a first mode in which hydraulic fluid flows through the solenoid valve to the second outlet and a second mode in which the solenoid valve blocks passage from the second inlet to the second outlet; anda check valve disposed between the first passageway and the second passageway, the check valve having a first end urged to close the first passageway to fluid from the second inlet and a second end connected to the second passageway for receiving pressurized hydraulic fluid from the second passageway to keep the check valve closed when the solenoid valve is in the first mode, the first end of the solenoid valve having fluid pressure from the first passageway applied thereagainst to open the second inlet to the first passageway when flow through the second passageway is blocked by the solenoid valve, wherein fluid from the second inlet flows into the first passageway and out of the first outlet rather than through the second outlet.
