  • Resilient sealing ring
    Patent number: 4990251
    Abstract: Resilient sealing rings are disclosed including an annular ring of resilient material having a cross-sectional configuration so that when not compressed the cross section of the sealing ring extends substantially longitudinally and when compressed between two parallel sealing surfaces the sealing ring bends so that the longitudinal ends approach each other. This provides acceptable compression force between the parallel sealing surfaces over an extended range of deformation particularly as compared to conventional O-rings.
