An alternating electric current integral pilot valve actuator and pilot valve. The magnetic flux core of the actuator is a short flux path through a "U" shaped magnetic material piece providing two pole pieces for a magnetic material valve member to be pulled against the two pole pieces which then completes the magnetic flux path, opens an integral pilot valve port and reduces the coil current to a lower level.

[ I claim:] [1.] A magnetically actuated valve including a housing, said housing having an electric coil, a magnetic flux core extending through the coil, said magnetic flux core having two core ends, said housing having an elongated opening extending outwardly from said two core ends, an insertable valve body with a press fit in said elongated opening spaced from said two core ends, an exit passage and an inlet passage extending through said valve body, a cooperating valve closure member positioned in said opening below said two core ends, core piece being attached to said valve closure member for moving said valve closure member to an open position, said magnetic flux core is U-shaped, said moveable core piece having two end faces, and said U-shaped magnetic flux core has one side of said U-shape longer than the other to be engaged by one end face of said moveable core piece when said moveable core piece is against said U-shaped magnetic flux core.
