Abstract

A hydraulic strut for a motor vehicle for providing a movement guiding and dampening function can generally have a cylinder, with a piston disposed in the cylinder to divide the cylinder into at least first and second chamber portions, with a piston rod extending from the piston out of the cylinder. The cylinder can be sealed at both ends, and can preferably be filled with hydraulic fluid. The piston can preferably define a flow connection between the two fluid chambers, and this flow connection can typically have some sort of valve arrangement therein for controlling flow of fluid between the first and second chamber portions.
