Abstract: An integrated resistive load bank management system (500) uses a load bank (510) to control a flow of electrical energy to an electrically operated system (520). The load bank management system uses a resistive load bank to dissipate power from a generator set (505). The load bank management system can rapidly switch an electrical connection between a load bank and the generator set and the electrically operated system and the generator set. The load bank management system can provide an instantaneous increase in power to the electrically operated system and provide a short recovery time between power pulses provided to the electrically operated system.

Abstract: A fuel injector includes an injector housing having a plunger assembly disposed within a central axial bore and including a lower plunger, an intermediate plunger, and an upper plunger. The lower plunger reciprocates within the central bore to meter a variable quantity of fuel during downward portions of the reciprocating motion. A timing spring is wound around the upper portion of the lower plunger to bias the lower plunger upwardly. A timing chamber formed between the upper and intermediate plungers receives timing fluid to create a hydraulic link between the plungers. Timing fluid exits the timing chamber through a central passage, which may have a reduced area regulating orifice, formed through the intermediate plunger, which is ordinarily closed by a valve mechanism. The valve mechanism is acted upon in part by the timing spring. To improve the pressure regulation using a higher spring load and to accommodate a larger area drainage passage, a valve spring biases closed the passage.
