Abstract (en)
The hydraulic drive comprises a working cylinder (12) in which a working piston (13) is movable and a spring storage arrangement (24) containing storage energy, with fluid under pressure in a container (20). The spring storage arrangement (24) supports an end of the cylinder housing (11) and with its other end being movable. The working cylinder housing acts upon the surrounding pressure piece (23). The container surrounding the working cylinder housing includes at least two axially running holes (21), in each of which a pressure piston (25) is slidably adjustable, on which a end face of the pressure piece (23) lies and on the other end face fluid under pressure is present.
