Abstract
A displacement element includes a first piston, a second piston, a cylindrical housing filled with a fluid under pressure, a piston rod, and a spring. Each of the pistons is adapted to the respective internal diameter of its section and divides the respective section into two pressure chambers. The first piston is arranged at one end of the piston rod, and both pistons each include means for damping the movement of the piston rod respectively in one direction. The second piston is arranged on the side of the first piston facing away from the piston rod and is capable of displacement by means of the first piston in a direction facing away from the open end. The spring is arranged on the side of the second piston facing away from the first piston, and supported by the second piston and the housing.
