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.

Abstract: A lubricating metering valve having an inlet chamber followed by a cylindrical chamber for discharge of the lubricant, a longitudinal tubular element being capable of permitting the refilling of the lower section of the discharge chamber, the element having a flange with openings therethrough to permit flow of lubricant and a longitudinal hole through the element, a sliding ring around the tubular element coupled with a lubricant discharge bushing located externally of the cylindrical wall of the tubular element, a coil spring actuating the discharge bushing upwardly, openings in the lower wall of the tubular element to permit flow into the discharge chamber, the holes being adapted to be closed by the bushing at the end of its downward stroke, a distributor-shutter element adapted for axial movement and located at the top of the valve, at its lower end the shutter element narrowing by two opposing truncated cones with a longitudinal hole adapted to be sealed by a rubber seal ring which prevents flow of lubri

Abstract: Pressure- and flow-regulating valve for automatic- or semiautomatic-cycle lubricating systems, principally characterized by being provided with a longitudinal bore subdivided into three aligned sections: in the intermediate section whereof there is coupled, with guided axial sliding, a piston element whose straight section has an area smaller than that of the intermediate bore section so as to permit oil to flow between the piston and the wall of the intermediate bore section; by the lower end of the piston terminating in an axial rod whose diameter is smaller than that of the piston to permit insertion of a coil spring around said rod; there being provided that the rod terminates in a spherical cap, intended to plug the last section of the longitudinal bore communicating with oil discharge when oil flows toward lubrication circuit and to re-open it when oil flow is interrupted.
