Electro-magnetically operated valve

摘要

An electro-magnetically operated valve (10) for control of pressurized fluid including a coil bobbin (5) disposed within a housing (8) having a plunger subassembly (31) mounted in a tubular chamber (20) provided in the coil bobbin having a fixed valve seat and a moveable valve body member disposed on a slidable plunger having flow passage means formed in said moveable plunger and having a magnet mounted at the opposite end from the valve body member whereby the plunger is moveable responsible to electronic coil mounted in the valve between an open position wherein the valve body member is in spaced relation with the seat permitting flow of pressurized fluid and a closed position whereby the valve body member is seated against the valve seat, the electro-magnetic coil is mounted in the bobbin whereby a magnetic circuit is formed including the moveable plunger and the valve is operated by positively controlling the opening and closing valve by passing a current through the magnetic coil of wire.
