  • Patent number: 4793372
    Abstract: A solenoid valve comprising: a stator; a coil responsive to current into thereto, and magnetically connected to the stator. The coil characterized such that its resistance changes with temperature to increase or decrease, as the case may be to vary the amount of flux generated. A valve seat positioned about one end of the stator defining a valve seating surface positioned at a predetermined distance for the one end and a flat armature movable relative to the valve seat and when seated thereon is spaced from the one end. The armature fabricated of a bi-metallic, thermally responsive element for causing a portion of such armature to move closer to or farther from the stator to vary the distance between such portion on the one end as a function of temperature to compensate for the changes in magnetic flux.
