ABSTRACT:
There is disclosed an improved grease lubricating assembly comprised of a lubricating cup positioned within a housing and having a spring-loaded piston assembly formed with a lubricating cup contact assembly which abuts the inner side walls of the lubricating cup under variable controlled conditions of friction to compensate for or cancel out any unnecessary force of the compression spring before exerting the necessary force or pressure against the container grease to effect controlled grease flow.
