Latest Patents
Ruttle holds a patent for a "Fuel injection pump with a hydraulically-spill valve." This invention is designed for use with relatively large diesel engines that utilize heavy diesel fuel. The fuel injection pump features a pump body that defines a portion of a fuel pressurization chamber, which is in fluid communication with a fuel outlet and a spill passage. The design includes a pressure control chamber and an actuation fluid passage. A spill valve member, which has a pressure surface, is exposed to fluid pressure in the pressure control chamber and is moveable between an inject position that blocks the spill passage and a spill position that opens the spill passage. Additionally, an electronically controlled valve has a control valve member that can move between two positions, allowing for efficient operation of the fuel injection system.
