Zusammenfassung:	A hydraulic or pneumatic device with a cylinder and piston system provides a rapid stroke and a power stroke. The piston part of the system consists of two lengthwise integrally connected piston-rod like plunger pistons, with different diameters. The cylinder is also provided with two working chambers, one for each piston, each working chamber at least partly surrounding its own piston. In each the pistons there is a passage connecting the two working chambers.
