Abstract: The present disclosure relates to a motor vehicle, comprising a leaf element, which is movably held at a bearing point of the motor vehicle, and an adjusting device by means of which the leaf element can be moved between a closed position, in which the leaf element closes an opening of the motor vehicle, and an open position, wherein the adjusting device comprises a spring component which, on the one hand, is coupled at least indirectly to the leaf element and, on the other hand, at least indirectly to a holding region of the motor vehicle, and which comprises a sleeve element and a piston element which is inserted into a sleeve interior of the sleeve element in certain regions and is displaceable relative to the sleeve element during the movement of the leaf element between the closed position and the open position. The spring component is designed as a spring strut and comprises a damping device for damping during the displacement of the piston element relative to the sleeve element during the movement of the leaf element between the open position and the closed position. A further aspect of the present disclosure relates to an adjusting device.

Abstract: A rail brake damper includes a cylinder-piston arrangement. A damping device assigned to the piston comprises at least one damping valve having at least one piston channel, which passes through the piston, connecting the two operating chambers of the cylinder, and a closure element assigned to the piston channel. The closure element is spring pre-loaded with the effect of closing the piston channel and is acted on by the hydraulic pressure which prevails in the operating chamber facing away from the piston rod with the effect of opening the damping valve.
