Abstract

The cylinder has a housing provided with an inner cylinder and a pressure port. A plastic guide sleeve (181) is fixedly connected with the housing with an attachment region (201) of the sleeve. A piston is movably arranged in the inner cylinder and another inner cylinder, for limiting a variable pressure chamber. A housing-fixed seal works together with the piston and with the housing and/or the guide sleeve. The attachment region and a section of a cylindrical cladding surface (191) of the sleeve are formed from different plastics, where the section works together with the piston.
