    摘要: The present invention relates to an improved fluid actuated system (10), such as those used in hydraulically actuated fuel injectors of an internal combustion engine (12). A fluid pump (18) supplies hydraulic fluid to a high pressure rail (14) that in turn supplies the fuel injectors (16) with high pressure fluid. Pump output control is provided by an actuator (51) and an electronic control module (52). A position sensor (58) provides data related to actuator position to the electronic control module (52). Pump control parameters are determined by the electronic control module (52), based on fluid pressure, engine operating conditions and actuator position.
