Patent ID: 7646273

Claim:
A solenoid actuator comprising: a coil bobbin; an excitation coil wound around said coil bobbin for connection with an external voltage source to be selectively energized thereby; a core configured to extend through said coil bobbin to have a first pole end and a second pole end which project outwardly of said excitation coil respectively at opposite axial ends thereof; an armature having an actuator leg extending outwardly of said excitation coil and along an axial length of said excitation coil; a hinge support configured to pivotally support said armature to said core for pivotal movement of said armature between an operative position and an inoperative position; wherein said armature is shaped to include an anchor leg which extends from one end of said actuator leg at an angled relation thereto, said hinge support is formed as an integral part of said coil bobbin and is disposed at one axial end of said core to place said anchor leg in close relation to said first pole end, and at the same time to place a portion of said actuator leg in close relation to said second pole end, said hinge support being configured to make said anchor leg in direct supporting contact with said first pole end, and wherein said actuator leg is angled to said anchor leg at an angle of less than 90 degree.
