Abstract

In a spring strut a piston rod is guided through a sealing ring which is accommodated within a groove. This groove has a localization line which has varying height above a reference plane axially fixed and orthogonal with respect to the axis of the cylinder of the spring strut. The groove is confined by two groove confining members which are shaped such that they can be manufactured by a non-cutting shaping process, such as injection-moulding or sintering.
