摘要

The spring (2) has a lid (4) provided with a fastening region (6), and a revolution piston (8) provided with a fastening region (10) at an upper end of the piston. Hose rolling bellows (12) are secured in the fastening region of the lid and in the fastening region of the piston. A locking collar (16) of a circlip (22) is fastened at the piston, where the circlip comprises a radially inward directed projection (28). The upper end of the piston and the projection cooperate such that the bellows are blocked between the upper end of the piston and the projection.
