Gas spring for lifting flap of motor vehicle, has base with region in which helical compression spring is axially supported by end of base, and another helical compression spring with ends coaxially guided into tube by guide part

摘要

The spring has a cylindrical pressure tube (1) with an inner region divided into two working chambers (3, 4) by an axially movable piston (2). A piston rod (5) is fastened to an end of the piston. A base (7) has a region in which a helical compression spring (11) is axially supported by an end of the base. A helical compression spring (20) smaller in length than the compression spring (11) is arranged within the compression spring (11). The helical compression spring (20) has ends coaxially guided into the pressure tube by a guide part (16), which is arranged in the pressure tube.
