  • Apparatus for lubricating wheel flanges of a railroad vehicle
    Patent number: 4763759
    Abstract: Lubricating equipment for wheel flanges of a railroad vehicle has a compressed air supply, and a generator (3) generating an air-oil mixture. Tubing extends from the generator to application nozzles (15) which have a profile that increases density of the air-oil mixture as well as the speed of the flow. The equipment releases oil in a micro-pulverized form onto the surface so that it is unaffected by air turbulence in the vicinity of the moving wheels.
