Abstract
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 a first position and a second position along the second axis, and a manifold mounted to the housing. The valve shaft is biased toward the first 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 displace the shaft to its second position. A poppet seal affixed to the shaft, which interacts with a portion of the housing to close an outlet port in the housing, and a spool seal, also affixed to the shaft which interacts with a wall of the manifold defining an exhaust port to route fluid to the desired port. An electronic circuit controls delivery of current to the solenoid to shift and hold the shaft in the second position.
