Abstract
A low-friction seal having a sealing ring seated in a groove formed by two relatively displaceable surfaces which are to be sealed, the ring resting by its periphery projecting from the groove against the surface to be sealed with a sliding fit, the sealing ring made of a dimensionally stable material and seated with axial and radial play in the groove, and means for pressure propagation between the groove sidewall closer to the pressure chamber and the sealing ring to the groove bottom using spacer means, and an axially projecting circumferential sealing ring provided between the groove sidewall away from the pressure chamber and the sealing ring, the active area of the sealing rim exceeding that of the spacer means between the sealing ring and the opposite groove sidewall.
