A solenoid valve has a housing defining a first axis and second axis, a solenoid which produces a magnetic field along the first axis, a valve shaft movable between open and closed positions along the second axis, and a manifold mounted to the housing. The axis is biased toward the closed position by a spring and mechanical forces sufficient to overcome the force of the spring are transferred from the solenoid to the shaft by a lever to open the valve and then hold the valve open. A poppet seal, which interacts with a portion of the housing to close the valve, and a spool seal, which interacts with portions of the manifold to route fluid to the desired port, are mounted to the shaft. An electronic circuit controls delivery of current to the solenoid to shift and hold the shaft in the open position. |
