Abstract

430,976. Lubricating-pumps. CHALMERS, R. A., and TECALEMIT, Ltd., Great West Road, Brentford, Middlesex. July 25, 1934, No. 21878/33. [Class 102 (i)] In a lubricating-pump of the type in which the suction port 4 is controlled by the plunger 2 and the discharge port 7 is controlled by a piston valve 3 which is pressed back by the discharge pressure against the action of a spring 9, the pressure on the valve 3 is balanced, the discharge taking place to the chamber containing the spring 9 past a check valve 17 to an axial or lateral discharge passage. The barrel 1 is inserted in a lubricant reservoir and the plunger 2 is operated by a cam. The stroke of the valve 3, and in consequence the pump discharge, is regulated by means of washers 12. As the plunger 2 and valve 3 come into contact all air is expelled from the cylinder.
