Lubricating device and its use for lubricating a wheel flange of a railway vehicle

摘要

Device for lubricating a wheel flange of a railway vehicle based on the spraying of a pressurized jet of lubricant, comprising an electromagnetic pump with a pump body (5) in which a piston (20) is displaced, and a means (19) for guiding the piston (20) in a bore (22), the guidance means (19) including an opening (32) designed to communicate with a lubricant transfer channel (17) in the pump body (5), said opening (32) opening out into a compression chamber (23) situated in a downstream part of the bore (22), the device comprising a heating block (7) arranged so as to transfer heat energy to the lubricant before spraying.
