Abstract
An actuator having a tubular body with a cylindrical bore therein within which a piston reciprocates, an output shaft extending into said bore and a linkage for converting the linear movement of the piston into the rotary motion of said shaft. The linkage is contained entirely within said bore. In one form the piston is spring loaded and a spring follower also provides a piston for compressing the spring to permit the force exerted on the piston to be transmitted to the output shaft substantially in its entirety.
