Abstract: A constant level oiler is disclosed which includes an adjustable nozzle assembly for establishing the operating or working level of the oil lubricant in the oil chamber and to a user assembly. A tool is further disclosed which is insertable into the oiler chamber for making the desired nozzle assembly adjustments.

Abstract: A porous rod for inclusion in a lubricant metering valve is provided with radially projecting means forming an annular shoulder intermediate the length of the rod. The rod is tightly enveloped in an impervious sleeve which extends over at least a portion of the length of the rod. An annular sealing member is disposed on the rod in engagement with the shoulder, the sleeve and the opposed wall of the bore of the valve. The sealing member is compressed into proper sealing mode with assembly of the male and female valve members to preclude passage of lubricant through the valve except by passage through the porous rod.

Abstract: An oiler assembly is disclosed for feeding a relatively precise and consistent lubrication. The assembly includes a supply of the lubricant and a flow line placing the supply in communication with the lubrication point. A metering valve is interposed in the flow line and generally comprises a body having an inlet and an outlet. The body further includes a bore having one end thereof in communication with the inlet and the other end thereof in communication with the outlet. A porous rod is disposed in the bore of the body. A sealing member is disposed in the bore to preclude the passage of lubricant from the inlet end to the outlet end of the bore except by passage through said porous rod.

An impervious coat on the rod extending over at least a portion of the length of the rod determines the length of the flow path for the lubricant passing through the rod. The impervious coat may be a plastic sleeve, peelable to alter the length of oil travel and so provide adjustment of the feed rate.
