Abstract: An automatic oiling device for delivering oil to a bearing comprising a sealable container defining a reservoir for oil with a opening in which a hollow tube is fitted. One end of the hollow tube communicates with the interior of the sealable container and the other end is open. Wicking material is located in the hollow tube and extends into the interior of the sealable container at one end and extends from the other open end of the hollow tube for contact with a bearing to be oiled. The hollow tube and the wicking material co-operating to function as an automatic valve to release oil from the sealable container as needed by the bearing. The wicking material is packed into the hollow tube to a density sufficient to allow for an automatic valving cycle that controls the flow of oil.

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.
