PCT No. PCT/SE94/00332 Sec. 371 Date Sep. 26, 1995 Sec. 102(e) Date Sep. 26, 1995 PCT Filed Apr. 15, 1994 PCT Pub. No. WO94/25775 PCT Pub. Date Nov. 10, 1994The invention relates to an arrangement for a gas spring (1). This consists of an outer cylindrical casing (1a) with a sealing end wall (1b, 1c) at either end. Of these, one (1c) has an axial bore for a piston rod (4a) passing through the bore, which piston rod is connected to a piston (4b) moving axially in the interior of the casing. The arrangement also consists of an annular cylindrical body (5) made of an elastic material. The outer cylindrical wall of the body (5) is operatively connected to the casing (1a) in a sealing fashion. The inner cylindrical wall of the body (5) is operatively connected to the piston (4b) in a sealing fashion. A certain gas pressure prevails in a space (9) defined by the cylindrical wall of the casing (1a), the other end wall (1b) and the piston (4b) and the annular surface of the annular cylindrical body (5) facing away from the end wall (1c) executed with a bore. Metal tubes (6a and 6b) are attached to the cylindrical surfaced of the body (5) in the form of an annular cylinder. These project beyond the body (5) in a direction towards the flange (11) and define an annular cylindrical space with the end wall (1c). |
