FLUID HOLDER AND ELECTROMECHANICAL LUBRICATOR EMPLOYING SAME

摘要

A fluid holder includes: a housing having an inner surface and at least one fluid outlet; a piston in slidable engagement with the inner surface and having first and second opposed surfaces with a threaded opening extending therebetween, the first surface of the piston and the inner surface of the housing defining a fluid chamber in communication with the at least one fluid outlet; and a threaded member engageable with the threaded opening, a first portion of the threaded member extending from the first surface of the piston, the threaded member being rotatably coupled to the housing on the first portion of the threaded member for rotation in the threaded opening of the piston such that rotation of the threaded member causes a force to be exerted by the threaded member on the housing and on the piston to expand or contract the fluid chamber.
