Abstract
A circular coolant seal has a base flange arranged in a base plane perpendicular to the seal axis. A flexible resilient sealing flange is integrally joined at one edge to the base flange and terminates at its opposite edge in a sealing lip located in a sealing plane parallel to and spaced axially from the base plane. The sealing lip has a first portion extending from the base flange angularly away from the base plane and inwardly towards the seal axis to an intermediate hinge portion, and a second portion extending from the hinge portion away from the seal axis and angularly towards the sealing plane. The configuration, flexibility and resilience of the sealing flange is such that axial displacement of the sealing lip in relation to the base flange is accompanied by both axial and radial displacement of the hinge portion.
