Abstract

An actuator system for controllably rotating a rotary (valve) element positioned in a pressurized fluid vessel. A double-acting piston-cylinder intermittently rotates a ratchet wheel operatively connected to the rotary element. The cylinder is sealed within a bel-lows chamber assembly in the vessel and is controllable by a pressure source positioned outside of the vessel. The wheel is rotated by a ratchet member biased against the ratchet wheel and attached to the cylinder and reciprocable therewith. A ratchet pawl biased against the ratchet wheel prevents the reverse rotation of the wheel, and thereby of the rotary element.
