Abstract (en)
[origin: EP1178220A2] The piston rod (7) of the pneumatic cylinder is in functional communication with a hydraulic damper unit which is installed inside the cylinder casing (1). The damper unit comprises two bellows (8a,8b) filled with hydraulic fluid and fastened on both sides of a center partitioning wall (5) which is fixed in relation to the cylinder casing and which has a restrictor orifice (9) for overflow hydraulic fluid. The outer ends of the two bellows are closed respective compressed air loaded piston (6a,6b).
