ABSTRACT:
An actuator assembly comprises a piston within an actuating cylinder, and a valve for controlling the flow of actuating fluid to the first side of the piston. When the valve is actuated the flow of fluid to the first side of the piston is stopped and the pressure of the actuating fluid on the piston is sufficient to maintain the piston in a predetermined position along the stroke path. Also disclosed is a method of actuating the crust breaker of a smelter pot using the apparatus described. Fluid leakage through the piston rod sealing assembly is reduced; the volume of compressed air used by the smelter is reduced; and the working life of the actuator is improved.
