Abstract

A cylinder and working chamber are formed in the slide (10), and the piston (24) is fixed in relation to the housing (11). T slide has a prismatic form. The sliding guide (12) in the housing is manufactured by a casting process. The piston divides the cylinder into two separate working chambers (13,29), the volume increase of which leads to opposed movement of the slide. Hydrau fluid lines are led to the working chambers through the piston and piston rod connected to it.
