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.
