Abstract

A compressed air landing strut 2 is disclosed with a pneumatic shock absorber which is set onto a spring support 14. The spring support 14 has an offset 22 and the end region 24 of the roll-off piston 12 is flared radially outward, so that it surrounds the offset 22. An O-ring 24 is radially compressed between the outer wall 40 of the spring support 14 and the inner wall 42 of the roll-off piston 12 and seals the spring space 4 of the pneumatic shock absorber air-tight against the environment. A method for the manufacture of said pneumatic shock absorber is also disclosed.
