ABSTRACT:
The invention relates to a working cylinder comprising a cylinder unit with a front end part, a rear end part and a cylinder tube connecting these end parts, a piston movable in the cylinder tube and a piston rod secured to the piston and extending through the front end part. The purpose is to provide a novel, simple solution for securing the cylinder tube to the end parts. Each end part has a shoulder, the cylinder tube being connected to each end part by means of a compression ring which upon deformation of the end of the cylinder tube and by means of said end tightly clamps the end shoulder.
