Abstract
A solenoid valve for use in controlling the flow of pneumatic fluid under pressure between a pair of flow ports defined by a housing. The flow of fluid is controlled by a spool disposed within a bore and is movable between first and second positions. When in one of the first and second positions, the spool blocks communication between the ports and when in the other of those positions it allows communication between the flow ports. The spool is reciprocated by a motor means which includes a core of magnetic material connected to the spool so that when the motor is energized, the spool is placed in one of its first and second positions and when the motor is de-energized, a spring moves the spool to the other of its positions.
