ABSTRACT:
A metering valve for the drop feeding of a liquid lubricant includes a metering assembly disposed in a valve chamber having an inlet and an outlet. The metering assembly includes a cylindrical member having a peripherally disposed spiral groove. A sleeve is press fit on the cylindrical member to render the groove a closed spiral metering channel. The metering channel communicates with an outlet in the cylindrical member that is generally aligned with the chamber outlet. An O-ring seal surrounds the aligned outlets and is disposed between the floor of the chamber and the metering assembly to preclude passage of lubricant from the chamber except by passage through the metering assembly.
