Abstract
A three-port flow control valve comprising a valve body having two opposite-facing valve seats disposed along a central bore terminating in an exhaust port. A supply port communicates with the first valve seat, and a common port communicates with the second valve seat. A pintle shaft connected to an actuating linear solenoid extends along the central bore. A first valve head actuated by the pintle shaft mates with the first valve seat. A second valve head disposed colinearly with the pintle shaft mates with the second valve seat. Opening of the first valve closes the second valve and vice versa. While the solenoid is de-energized the supply pressure keeps the first valve closed. A spring may be disposed between the second valve head and the exhaust port to urge the second valve head to close with the second valve seat.
