An automatic oiling device for delivering oil to a bearing comprising a sealable container defining a reservoir for oil with a central opening in which a hollow tube is fitted. One end of the hollow tube communicated 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. The automatic valving cycle involves capillary flow of the oil from the reservoir through the wicking material to the bearing, the flow of oil lowering pressure in the sealable container which eventually results in the capillary flow being curtailed, whereupon the lowered pressure in the sealable container is sufficient to draw air through the wicking material and into the sealable container to increase the pressure in the sealable container such that capillary flow resumes and the automatic valving cycle is repeated.
