Embodiment Construction

[0027] The shut-off valve 11 is used in combination with a shock absorber (not shown) in the assembled state. To this end, the shut-off valve 11 is connected to the valve block of the shock absorber, which is located, for example, at the bottom of the shock absorber tube. The valve block includes the channel system required for the hydraulic supply and connected to the damping valves for the compression and rebound stages. There is no restriction at all on the type of shock absorber, as long as it includes a hydraulic device by which kinetic energy is converted into thermal energy by fluid friction. This is done in a known manner by virtue of the fact that the flow of hydraulic fluid through the valve channel is braked.

[0028] The shut-off valve 11 is arranged on the shock absorber. This means that the shut-off valve 11 is integrated into the shock absorber, ie forms part of the shock absorber. The connection of the shut-off valve 11 to the valve block of the shock absorb...

Abstract

The invention relates to a shock absorber, a vehicle, the use of a shut-off valve and a method for filling. A shock absorber, in particular for a motor vehicle, having a hydraulic device for damping vibrations, at least one shut-off valve (11) being fluidly connected to the hydraulic device at the shock absorber and able to fluidically Connected to a pump and / or filling device for filling the shock absorber with hydraulic fluid.

Description

technical field [0001] The invention relates to a shock absorber, a vehicle, the use of a shut-off valve and a method for filling a shock absorber. Background technique [0002] Shock absorbers for motor vehicles with hydraulic means for damping vibrations are known. The shock absorber's hydraulics convert kinetic energy into heat through fluid friction. This is done in a known manner by virtue of the fact that the flow of hydraulic oil is braked through the valve channel. Active damping systems are known that connect the compression and rebound stages of the shock absorber to an external electric pump. The pre-assembled electric pump is usually delivered together with the shock absorber as a unit filled with hydraulic oil. If the installation space in the vehicle is limited and the assembly of the active damper is hindered due to the restricted installation space, problems may arise during the final assembly of the active damper. Contents of the invention [0003] It ...
