Abstract
A hydraulic system for a hydraulically adjustable vehicle shock absorber including a piston and at least one pressure chamber cooperating hydraulically with the piston, a hydraulic pump configured so as to convey the hydraulic fluid (F), and a hydraulic conduit assembly, via which the at least one pressure chamber of the hydraulically adjustable vehicle shock absorber is connected to the hydraulic pump. At least one elastically deformable damping element is in contact with the hydraulic fluid (F).
Claims16
A hydraulic system comprising:
- a hydraulic pump configured to convey a hydraulic fluid,
- a hydraulically adjustable vehicle shock absorber comprising a piston rod, a piston that is fixed to one end of the piston rod such that the piston moves with the piston rod, and a first pressure chamber and a second pressure chamber which hydraulically cooperate with the piston in an opposing manner,
- at least one elastically deformable damping element that is positioned to be in contact with the hydraulic fluid, and
- a hydraulic conduit assembly via which the first and second pressure chambers of the hydraulically adjustable vehicle shock absorber are connected to the hydraulic pump,
- wherein the at least one elastically damping element comprises a first deformable damping element arranged in the first pressure chamber and a second deformable damping element arranged in the second pressure chamber,
- wherein the first deformable damping element is arranged on a first surface of the piston that delimits the first pressure chamber, and the second deformable damping element is arranged on a second surface of the piston that delimits the second pressure chamber.

A hydraulic system comprising:
- a hydraulic pump configured to convey a hydraulic fluid,
- a hydraulically adjustable vehicle shock absorber comprising a piston and at least one pressure chamber that cooperates hydraulically with the piston,
- at least one elastically deformable damping element that is positioned to be in contact with the hydraulic fluid and arranged at at least one port of the hydraulic pump through which the hydraulic fluid either enters or exits the hydraulic pump, and
- a hydraulic conduit assembly connected to the at least one port via which the at least one pressure chamber of the hydraulically adjustable vehicle shock absorber is connected to the hydraulic pump,
- wherein the at least one elastically deformable damping element has an opening that defines either an entrance or exit to the hydraulic pump such that the hydraulic fluid is forced to either enter or exit the hydraulic pump via the opening.
