ABSTRACT:
The actuator comprises a cylinder of non-circular cross section, two types of pistons and a piston rod which is provided with at least one spiral male thread having a pre-determined helical angle at a pre-determined pitch. One of the piston is mounted on the piston rod for rotation relative thereto while being fixed against axial displacement therealong, and is provided with two relief pressure control valves opening in respective opposite directions, and the other piston is provided with at least one female spiral thread engaged with the male thread on the piston rod. The rod can thus reciprocate in the cylinder in opposite axial directions and can rotate, relative to the cylinder, in opposite angular directions.
