ABSTRACT:
A lubricant seal is provided for use in the lubrication of rotating or reciprocating members which are subject to very severe ambient conditions, such as the stems of inlet or exhaust valves of internal combustion engines. The lubricant seal comprises a tubular member of elastomeric material having a first portion surrounding the movable member and a second portion that fits tightly on a bushing guiding the movable member. The first and second portions are connected by a flexible bellows element which compensates any misalignment between the movable member and the bushing. A metering ring made of a self-lubricating material is anchored in the first portion of the tubular member and has a bore closely fitting the periphery of the movable member. An oil accumulating receptacle is defined on the exposed face of the metering ring and capillary passages are provided in the ring which permit the self-controlled and metered flow of lubricant through the ring and into the space between the movable member and the bushing.
