Gas in a second chamber is compressible in order to maintain a continuous spring force applied against the piston (2). By means of pressure medium in the first chamber (8), the piston is pressed into the cylinder, reducing the volume of the second chamber. - The second chamber comprises a central part space (10) inside the cylinder, and a second such space (10') located axially with and outside the cylinder (1). This minimises the total length of the mechanism. |
