System, device and process for the lubrication of leaf mechanisms

摘要

A delivery system for lubrication of the doors of a railway carriage comprises a tank (10) in which are provided one or more outlet openings (14) connected to the said doors and an inlet opening (16) for placing a lubricating substance within the tank. The system is connected to a source of compressed air communicating with the interior of the said tank (10) through an opening (16). In use the source of compressed air is selectively activated on the basis of a predetermined number of opening and/or closing movements of each door in order to permit selective delivery of the said lubricating substance from within the tank (10) to each door of the railway carriage.
