Abstract (en)
[origin: WO2006069899A1] The invention relates to a fuel injector (10) with direct control of an injection valve body (48). An actuator (14) is housed in a cavity (12), pressurised by high pressure fuel from a high pressure source (22) outside the fuel injector (10). The actuator (14) is active in the closed position of the injection valve body (48) and not active in the open position of the injector valve body (48). The actuator (14) acts directly on a converter piston (24) of a pressure converter (100) which pressurizes the conversion chamber (36). A control chamber sleeve (31), defining a control chamber (46) is displaceably housed in the converter piston (24).
