ABSTRACT:
In a cylinder with a two-stage movement, a first piston moves in a housing, and in the first piston a second piston moves, which has a piston rod sliding in an end of the housing. On its side facing away from the piston rod, the second piston is provided with a guide member which is guided in the first piston. The first piston can be held in a position in which the piston rod is extended far out of the housing. With the aid of the second piston, the piston rod can perform a certain axial movement relative to the first piston, at the same time as guiding is effected with the aid of the guide member and the first piston.
