277 65, 277 84, F16J 1532
Radial gaskets for use in connection with shafts which are axially movable within a cylinder containing a pressurized fluid, particularly in connection with McPherson type dampers. The gaskets include a rigid support ring and a shaped body of flexible sealing material having a lip on the surface of the shaft which when submitted to fluid pressure forms a cutting angle substantially equal to 90.degree. when the gasket is in its working condition. In this manner, the scraping effect of the gasket is increased and the possibility of fluid blow-out and the resultant stresses due to fluid pressures are avoided without negatively affecting the positioning of the lip with respect to the relevant articulation line of the gasket.
