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.

Low power solenoid actuated valve

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 shaft 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 displace the shaft and then hold a first poppet valve open. The first poppet valve, which interacts with a portion of the housing to close the first valve, and a second poppet valve, 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.
