Abstract

An oscillating, two-pipe, hydropneumatic oscillating damper, with piston rod guide, of several parts, constituted by a cylinder having a liquid charge, a piston provided with damper valves sliding on said cylinder and this piston being fixedly fixed a piston rod which seals towards the inner cavity, and being driven in the piston rod guide that serves to center the cylinder in the container, while between the inner surface of the container and the outer surface of the cylinder there is a annular compensation chamber that is communicated with the inner cavity of the cylinder, characterized in that the guide (5) of the piston rod has a relatively thick wall bushing (7), and said bushing, (7) has an appendix (9) oriented in the direction to the plunger (3), the outside diameter (10) of this appendix (9) corresponding to the inside diameter of the cylinder (1), and forming the first the centering collar for the cylinder (1).
