ABSTRACT:
A rotary solenoid having an output shaft that is indirectly coupled to the rotor or armature of the solenoid, for rotation independently of or coupled to the solenoid. In one application of the solenoid the shaft is rotated through a limited range by a bimetallic torsional element, which is overridden by operation of the solenoid to increase the range of rotation. The range of travel can be limited by a disc having a slotted peripheral flange between the solenoid rotor and the output shaft. The armature has an integral hub and spaced poles with the pole pieces being rotatably positionable within the space between the hub and poles. Structure of the unit is very simple and all parts are readily accessible for adjustment and servicing.
