摘要

The injector (1) has a twin-pilot valve component (31) provided with two pilot valves (33, 35) and a nozzle needle (15). Each pilot valve is fixed with an actuator (39, 41). A rotary valve is connected with the pilot valves. An axial valving part (43, 45) extends along the actuator. A flow path is provided in low pressure side and a control space (17). The pilot valves are arranged in two branches. Two outlet throttling devices are connected with the two branches. A valve body (69) is fixed with the outlet throttling devices.
