Abstract
A strut with an air-filled cushion and comprising a bellows (1) that rolls down over a surface (3), a hydraulic dashpot accommodated inside the bellows or surface, a piston rod (5) that travels in and out of the dashpot, and an upper and lower closing and fastening component provided with seals, whereby the seals are O rings. The object is a simple approach to sealing the interface between the closing and fastening components and the dashpot that will still allow a reliable seal by means of O rings. Each O ring (9 & 10) is accordingly accommodated in a recess both radially and axially open at one side in the upper component, rests radially against the lower component, and is fixed and/or tensioned axially by a ring (14) fastened to the upper component or by a disk (12).
