Abstract
A lubrication system mounted on a railroad locomotive for applying a lubricant to a rail. The system is comprised of a manifold that defines a generally endless, closed lubricant path. A pump is provided to continuously convey a lubricant along the lubricant path. A reservoir for holding the lubricant defines a portion of the lubricant path. A dispensing nozzle is mounted to the locomotive above each rail for directing the lubricant onto each rail. A metering device is associated with each dispensing nozzle. Each metering device is connected to the manifold and an associated nozzle for diverting a metered amount of the lubricant from the lubricant path to the associated nozzle.
Claims22
A lubrication system mounted on a railroad locomotive for applying a lubricant to a rail, said system comprised of:
- a manifold defining a generally continuous, endless, closed lubricant path;
- a reservoir for holding a lubricant, said reservoir defining a portion of said lubricant path;
- a circulation pump that is operable during operation of the lubrication system to continuously convey said lubricant from said reservoir, through said manifold and back to said reservoir;
- a dispensing nozzle mountable to said locomotive above said rail for directing said lubricant onto said rail;
- and
- a metering device associated with said dispensing nozzle, said metering device connected to said manifold and said associated nozzle for diverting a metered amount of said lubricant that is being circulated through said manifold from said lubricant path to said associated nozzle.
A lubrication system mounted on a railroad locomotive for applying a lubricant to a rail, said system comprised of:
- a lubricant circulation system operable to continuously circulate a lubricant along a generally continuous, endless, closed path;
- a purge system including a tank for holding a cleaning fluid;
- a metering and dispensing assembly connectable with said lubricant circulation system and with said purge system, said metering and dispensing assembly including:
- a dispensing nozzle mounted relative to said locomotive for directing said lubricant onto said rail,
- a metering device associated with said nozzle for metering a fluid to said dispensing nozzle, and
- a controller for selectively controlling connection of said metering and dispensing device to said lubrication circulation system and said purge system, said controller having a lubricant dispensing mode for connecting said metering and dispensing device to said lubricant circulation system, and a purge mode for connecting said metering and dispensing device to said purge system.
