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.
