Metering valve for lubrication and systems using same

Abstract

A metering valve includes its operative parts and a casing in the shape of a cartridge and has, along all or most of its length a given diameter, an entrance bore and an exit bore, the operative parts being enclosed in the casing. The bottom of the casing is flat at the oil entrance side. The casing may extend at the oil entrance side to form a substantially cylindrical tang of the given diameter with flattened portions opposite one another. A smaller, threaded tang extends from the substantially cylindrical tang, the tangs being bored for entrance of the oil into the valve. The casing, as well as the tangs if present, is so shaped that it can fit into a bore provided in a machine part to be lubricated or a distributer. The distributer is preferrably of modular construction, a plurality of the modular pieces being of substantially like construction, each having a deviation bore therein to receive a metering valve and opposite flat surfaces having therein respectively a male and female dovetail element.
