Abstract
In a vibration damper or shock absorber for a vehicle, an axially extending cylinder is positioned within a similarly axially extending container with an annular reservoir formed between them. A piston rod extends through a guide in one end of the cylinder and includes a piston axially slidable within the cylinder for dividing it into a pair of working spaces interconnected through a damping device in the piston. One of the working spaces is in fluid connection with the reservoir. A connection is provided between the piston rod guide and the container and includes an annular groove in the guide and a projection from the container extending into the groove. Further, a sealing ring is provided between the guide and the container axially outwardly from the projection-groove. A certain amount of axial play is afforded between the container and the piston rod guide.
