<p>A lubricant supply apparatus is mounted on a rolling stock car travelling on rails to supply a lubricant to wheel edges and/or rail edges. The apparatus has a pressurized oil pipeline system, a pump mechanism, a pump drive mechanism, a connecting member, and a nozzle. Air pipes are not used in the pipeline system of this apparatus. The pump drive mechanism has a coil through which a DC current flows. The amount of lubricant to be delivered is controlled by the connecting member. The nozzle has a valve mechanism to maintain the pipeline at a predetermined pressure. Therefore, the lubricant is injected in a rod shape and at a high speed toward the wheel edges on the rail edges.</p> |
