Abstract

A seal 41 for a coolant pump of an internal combustion engine includes an annular cup 51 which is secured to the pump shaft and a tubular cartridge 42 is secured to the pump housing. The cup 51 carries an annular seal ring 53 having one face engaged by an annular seal ring 61 carried by the cartridge 42 and biased axially into engagement with ring 53 by a spring 87. The ring 61 is sealed to the cartridge 42 by a flexible annular bellows 66 surrounding the spring 87. The seal parts are subjected to high rotational torques during operation and are constructed and assembled to accommodate these torques. The bellows 67 has a composition which withstands the engine coolant on one side and oxidation on the other side, and has strengthening ribs. The seal rings are of a material and have dimensions to reduce the magnitude of the rotational torques. The seal components are secured together by coolant resistant adhesives to prevent their separation by rotational torques. <IMAGE>
