摘要: A stator assembly for a fuel valve comprising a magnetic E-core of stacked E-shaped laminations, a plastic bobbin proportioned to surround a central leg of the core, a magnetic wire coil on the bobbin, a non-magnetic metal plate having an O-shaped profile adjacent an end of the bobbin and distal ends of central and outer legs of the E-core, the core, bobbin, coil and plate encapsulated in a block, the block having a pair of vent channels overlying portions of the plate disposed between the outer core legs and the central core leg, the plate being proportioned to pre-stress the outer core legs outwardly prior to encapsulation whereby cyclic strain on the block due to hydraulic forces imposed by high pressure fuel pulses tending to spread the outer core legs is reduced and resistance of the block to cracking due to said fuel pressure pulses is increased.
