Annular sealing assembly for insertion between two mechanical members in relative motion, in particular a linear reciprocating motion, as a rod and the relative guiding seat of a mono-tube shock-absorber

摘要

A sealing assembly (1) including a sealing ring (10) made of elastomeric material and having, integrally in one piece, at least one elastically deformable, annular sealing lip (11), at least part of which projects axially from and radially inwards of the sealing ring, from a respective root portion (12) adjacent to a first axial end of the sealing ring, and towards a second axial end, opposite the first, of the sealing ring; and an annular reinforcing structure (20) made of material which is elastically deformable but relatively much more rigid than the elastomeric material of the sealing ring and relative lip, and at least partly embedded in the sealing ring; wherein the reinforcing structure (20) extends at least partly in an axial direction, at least partly alongside but on the opposite side to the sealing lip (11); the sealing lip being designed to define, when undeformed, a predetermined radial clearance (G) between itself and a radially inner lateral wall (21)of the sealing ring.
