The piston or the area of the piston rod operates via hydraulic oil against the effect of a spring function, the purpose of which is to ensure that the fluid is under pressure at all times. A moving device (7) interacts both with the fluid an with the aforementioned main spring (1), which for this purpose is so arranged as to provide the double function of serving both as a load/mass supporting spring and as a compression spring. |
