Abstract
An apparatus and a method for the filling of pressurized lubricant reservoirs such as is found on air oilers and the like. A storage tank of lubricant capable of being pressurized for the delivery of the lubricant to the individual lubricant reservoirs on one or several pieces of machinery or tools. The storage tank is connected with at least a line and a valve to a source of pressurized air that will be used to overcome a threshold pressure required to move the lubricant from the storage tank to the individual lubricant reservoirs. The storage tank may be connected to a piping manifold with valves to isolate lines leading to individual lubricant reservoirs. Check valves may be used as appropriate to prevent backflow of lubricant from an individual lubricant reservoir to the manifold, other commonly connected individual lubricant reservoirs, the storage tank, or the source of pressurized air, such as an air compressor.
