ABSTRACT:
A hydraulic cylinder comprises a piston assembly with a piston and a piston rod, a cylinder housing with a housing bottom, a pressure chamber in the cylinder housing delimited by the piston and housing bottom, a spring element which prestresses the piston assembly away from the housing bottom, and a fixing element which fixes the piston assembly in a predefined stroke position relative to the cylinder housing prior to first actuation of the hydraulic cylinder and is designed to release the piston assembly relative to the cylinder housing upon first actuation of the hydraulic cylinder. The spring element is arranged on the side of the piston which is remote from the pressure chamber, whereas the fixing element is provided in the pressure chamber at the housing bottom and co-operates with a mating element on the piston to releasably fix the piston assembly relative to the cylinder housing.
