<p>An electro-magnetically operated valve for control of pressurized fluid including a coil bobbin (105) disposed within a housing having a plunger subassembly (131) provided in the coil bobbin (105) having a fixed valve seat and a moveable valve body member (101). The plunger subassembly (131) includes a magnet (104) mounted at the opposite end from the valve body member whereby a plunger (103) is moveable responsible to electronic coil mounted in the valve between an open position and a closed position of the valve body member (101). A sensor means (168) sensing phase relations of a piston (142) of a pump body (140) is connected to the valve body means for timing the opening and closing of the valve. A control means is operably connected to the coil bobbin via a switch apparatus (170) for forming a magnetic circuit with the magnet of the plunger for operationally urging the plunger subassembly between the open and closed positions.</p> |
