ABSTRACT:
An actuator for converting axial movement into incremental rotation. Axial movement of a plunger provides successive increments of rotary motion of a shaft in a first direction through a predetermined angle, then automatically provides successive increments of rotation of the shaft in a reverse direction. After moving through a predetermined angle in the reverse direction the shaft rotation is again automatically reversed so the shaft rotates in the first direction.
