Abstract

The hydraulic actuator has a cylinder tube (1), a piston-rod guide flange (2) and a cylinder base (1). A primary piston (4) provided with a piston rod (6) is arranged inside the actuator. Furthermore, a secondary piston (11) connected to two plungers (7, 8) is arranged inside the actuator. The plungers plunge into two bores (5, 6) of the primary piston. Two unlockable non-return valves (17, 18) preloaded by springs (19, 20) are provided in the cylinder base. Located in the non-return valves is one bore (41, 42) each, which connects the front side to the rear side of the respective valve. The rear parts (24, 25) of the valve chambers (26, 27) each have an unlocking piston (21, 22) designed as a ball. Two feed lines (23, 30) for the hydraulic fluid are connected to the non-return valve chambers, these chambers in turn having feed lines at various points of the inner space (16, 40, 45) of the actuator. A very compact type of construction can be made possible for the hydraulic actuator with pressure intensifier.
