The Shuttle Distributor for a Diesel Fuel Injection Pump 770083

A simple valve is used in a Diesel fuel injection pump to allow each plunger to distribute fuel to two cylinders. The APS pump, based on this design, is both smaller and less expensive than an equivalent conventional pump because there are half as many pumping elements as engine cylinders. The APS pump has also shown significant performance advantages due to the action of the shuttle valves. A hydraulic governor has been designed and has been incorporated into the APS pump. This paper discusses the design and performance features of the APS pump.
