Device for resiliently suspending a piston on a closed-off hydraulic column
A volume spring element 152 is located inside the piston 10 which is open to the cylinder 20. The spring element 152 is surrounded by hydraulic liquid on all sides except at its surface 1521 at which the element 152 is attached to the piston 10. When the hydraulic pressure increases, the volume spri...

| description | A volume spring element 152 is located inside the piston 10 which is open to the cylinder 20. The spring element 152 is surrounded by hydraulic liquid on all sides except at its surface 1521 at which the element 152 is attached to the piston 10. When the hydraulic pressure increases, the volume spring element is compressed thereby decreasing its volume. When the hydraulic pressure decreases, the volume spring element expands again. When the hydraulic cylinder is closed off by a valve, then the hydraulic liquid in the piston 10 and in the cylinder 20 is disposed in a closed-off space or chamber. Axial pressures on the cylinder cause a pressure increase in the hydraulic medium. This causes the volume of the volume spring element to be decreased and the piston to be moved axially by the amount corresponding to the decrease of the equally large oil volume in the piston. With the reduction of the hydraulic pressure, the volume spring element expands again causing an axial movement of the piston in a direction out of the cylinder 20. The volume spring element effects the shock absorption of a saddle support which can be hydraulically positioned. |
