ABSTRACT:
To connect the cylinder pipe (1) of a hydraulic cylinder to a bottom (6), and a cover (8), the bottom (6) and cover (8) have groove-shaped recesses (16, 17), into which are pressed the ends (5, 7) of the cylinder pipe (1) under permanent deformation. To enable pressurization at high operating pressures, the region (25) of the inner end of the non-deformed cylinder pipe (1) is defined as a holding region (18, 19) and has a turned groove (26) which, in the deformed state of the cylinder pipe (1), reaches over the related inner edge (27) of the groove-shaped recesses (16, 17) with respect to the longitudinal stretch of the cylinder pipe (1).
