Abstract: A high torque reversible stepping actuator for valves can drive in small increments in response to fluid pressue pulses. The stepping actuator has oppositely facing ratchet wheels on a common shaft linked to the stepping actuator output. A pair of operator means can drive the ratchet wheels in opposite directions. Each operator means comprises a fluid pressure actuator connected to a drive pawl for driving one of the ratchet wheels in one direction. A pair of locking pawls normally engage the ratchet wheels preventing rotation in either direction. The fluid pressure actuator disengages one of the locking pawls sequentially before engaging the drive pawl with the ratchet wheel, thereby permitting advance of the ratchet wheel. The other locking pawl remains engaged and prevents back drive of the ratchet wheels and stepping actuator due to elastic deformation of the drive train connecting the ratchet wheel with the valve or other mechanism being driven.
