  • Fluid-filled piston cylinder unit
    Patent number: 10203017
    Abstract: A fluid-filled piston cylinder unit comprises a housing with a longitudinal axis and with an interior, a piston rod guided out from the housing in a sealing manner, which can be displaced along the longitudinal axis, as well as a piston connected to the piston rod, which divides the interior into a first sub-interior and a second sub-interior. The piston has a first fluid channel and a second fluid channel in each case for a fluid flow between the first sub-interior and the second sub-interior. The piston has a piston valve for closing the first fluid channel, whereby the piston valve in dependence of a fluid pressure opens the first fluid channel.
