Abstract

A hydraulic drive having a driving piston-cylinder arrangement, the working piston (13) of which, via a piston rod (14), drives an actuating device, preferably a high-voltage circuit-breaker, having a pressure piston-cylinder arrangement (29, 36), by means of which hydraulic fluid is provided for driving the working piston-cylinder arrangement (13, 11, 12), and having a spring store arrangement (16,17), the stored energy of which is transmitted to the pressure piston-cylinder arrangement (29, 36), the spring arrangement concentrically surrounding the working piston-cylinder arrangement (13, 12, 11), the pressure piston (36) being an annular piston, which surrounds the cylinder body (11) of the working piston-cylinder arrangement and is actuated by the spring arrangement (16, 17) in an annular chamber (31), the hydraulic fluid being present in that section of the annular chamber (31) which is situated on that side of the annular piston (36) which is opposite to the spring arrangement.
