摘要： A device having two glands leading a piston rod the glands being located at one side of a piston, whereas an inner gland divides the chamber inside the closed cylinder into a working chamber limited axially by an inner surface of a bottom and into a lubricating chamber limited axially by the inner surface of the outer gland. The working chamber has a flow zone shaped as the cylinder with its inner diameter increased, placed adjacent to the inner gland, as well as the compression zone, whereas the inner diameter of the cylinder is slidingly fitted with the outer diameter of the piston.

摘要： A vibration damper with stroke-dependent damping force includes a cylinder in which a piston rod with a piston is axially movable. The piston divides the cylinder into two work spaces filled with damping medium. A bypass between the work spaces is opened or closed depending on the piston position. The piston has a damping valve for at least one through-flow direction formed by a valve body that partially covers a through-flow channel in the damping valve. The valve body has first and second pressure-actuated surfaces on opposite sides of the valve body. The action of the second pressure-actuated surface depends on the position of the piston in relation to the bypass. The first pressure-actuated surface exerts a lifting force and the second pressure-actuated surface exerts a closing force on the valve disk. The second pressure-actuated surface is connected to a control space and a connection channel that overlaps with the bypass depending on the stroke position of the piston.

摘要： 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.

摘要： A dual tube shock absorber includes a spool valve located between the upper working chamber and the reserve chamber. The spool valve moves with the piston rod to open and close a flow path between the upper working chamber and the reserve chamber. This provides a low damping characteristic for small movements of the piston rod which changes to a high damping characteristic for larger movement of the piston rod.

摘要： A two-stage piston has a twin piston design where one piston produces a high damping force and the second piston produces a low damping force. At specified positions along the pressure tube, by-pass passages are formed to allow fluid flow around the high damping force piston to provide a low damping force or a soft ride. In the areas of the pressure tube where there are no by-pass passages, the high damping force piston provides a high damping force or a firm ride. In the area of the pressure tube where there are no by-pass passages, the high damping force piston and the low damping force piston both contribute to the high damping force.
