Gas pressure spring with temperature compensation, and method for producing the gas pressure spring

Abstract

The invention relates to a gas pressure spring (50) comprising a working piston (2) which is guided displaceably in a working cylinder (1) along a stroke axis (H), a compensating cylinder (12) which encloses the working cylinder (1), and a compensating piston (10) which is of hollow-cylindrical shape and is guided displaceably in the compensating cylinder (12) along the stroke axis (H). The working cylinder (1) has an open end (1b), at which the compensating cylinder (12) forms a projection (15) beyond the working cylinder (1) with a closed end (15b). The compensating piston (10) separates a working chamber (1a) which is arranged in the working cylinder (1), a compensation chamber (12a) which is arranged between the working cylinder (1) and the compensating cylinder (12), and a restoring chamber (15a) arranged in the projection (15) from one another and is open at an upper side (10a) of the balancing piston (10) facing the working chamber (1a). The gas spring (50) comprises a seal (8) arranged on the upper side (10a) of the balance piston (10) which seals the balance piston (10) to the working cylinder (1) and to the balance cylinder (12).
