Abstract: 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.

Abstract: Divider device for a flow of lubricant carried by a gas, typically air, comprising a distribution barrel (4) having an end face (5) into which run longitudinal distribution channels (6, 7) communicating with outlet orifices (8, 10) and a connection piece (18) mounted upstream of the distribution barrel (4) and comprising a hollow body with a bore (20) through which the flow of lubricant and gas can pass. The bore (20) of the connection piece (18) has a localized throttling region (26) of reduced cross section followed by a region (22) of enlarged cross section, and there is a gap defining a chamber (25) between the connection piece and the distribution barrel.
