Abstract
Power unit for use as a drive mechanism e.g. for deforming a workpiece, comprising a working piston 3 movable in a cylinder (2), or a rotary piston, Fig. 5 (not shown), a working member (4), an energy store 14 which is connected constantly to a primary cylinder space 10 generating the drive power, while the secondary cylinder space 11 on the other side of the working piston contains a pressure medium which provides before the start of a working stroke a counterbalancing force on the working piston, and a control device for the expansion of the secondary cylinder space (11), comprising at least one auxiliary piston (27 to 30) which in use abruptly increases the volume of the secondary cylinder space and thereby effects a rapid expansion of the secondary cylinder space, the working piston (3) being couplable with the working member (4) in the working direction for the transmission of the drive energy and being uncouplable in the opposite direction. <IMAGE>
