Abstract
A gas exchange valve arrangement, especially for an internal combustion engine, with a valve head, which is mounted on a valve body. The valve body can be moved in a straight line in either of two opposite directions by an actuating element, which can be moved in either of the two directions of movement such that, as a result of a movement of the actuating element in at least one direction, the valve body is caused to move in the same direction. The actuating element comprises a piston, which can be moved relative to a space by a fluid medium. The space comprises a feed opening for the fluid medium, and the gas exchange valve arrangement includes a throttle device, which at least temporarily throttles the movement of the actuating element in at least one direction of its movement.
