Abstract: PURPOSE: A fuel injecting device for a diesel engine is provided to reduce number of components, to reduce leakage of fuel, and to precisely control fuel injection timing. CONSTITUTION: In an off state of a solenoid(310), a valve unit(309) of an electronic valve(323) blocks an outlet orifice(305). Thus, a controlling pressure chamber(307) and the outlet orifice are separated from a low pressure fuel passage(314). Therefore, fuel pressures in the controlling pressure chamber, an inlet orifice(304), and the outlet orifice are increased. The pressures are operated to a control piston(307) and a needle valve(301). Moreover, the pressure area of the control piston is larger for preventing injection of fuel. In an on state of the solenoid, the valve unit opens a fuel hole of the outlet orifice for connecting the controlling pressure chamber to the low pressure fuel passage. Herein, flow amount from the controlling pressure chamber to the low pressure fuel passage is controlled by the outlet orifice. Therefore, decreasing speed of the fuel pressure in the controlling pressure chamber is slow. The needle valve is lifted with the control piston for starting fuel injection. Herein, the needle valve is slowly lifted for lowering initial injection rate.
