Abstract: A grease lubricating system includes a plurality of injectors for distributing grease to a plurality of lubrication points, an injector reset valve for resetting the injectors and a pump for supplying grease. The injector reset valve is located between the pump and the plurality of injectors and includes a piston and a large heavy duty spring which urges the piston into sealing engagement with an inlet port of the injector reset valve during a reset position of the valve. During a pressurizing portion of a pump cycle, grease entering the injector reset valve moves the piston out of sealing engagement with the inlet port of the injector reset valve enabling grease to flow from the inlet port through an internal chamber of the injector reset valve and out of a outlet port to input ports of the injectors through an injector distribution junction. Each injector then delivers grease to its respective lubrication point.

Abstract: A device for controlling the application of lubricant to parts of a locomotive or a vehicle is taught. Briefly stated, the distance traveled by the locomotive or the like is computed, with lubrication to a component then being provided. The distance between lubrication application may be adjusted, as well as the amount of lubrication being applied. Further, this rate and amount of lubrication, as well as the use of lubrication at all, can be manually or automatically adjusted according to various sensors such as braking, sanding, reversing curves or the like.
