ABSTRACT:
An accumulator fuel injection apparatus for an internal combustion engine is provided which includes a solenoid-operated fuel injector. The fuel injector includes a solenoid valve and a needle valve. The solenoid valve establishes and blocks fluid communication between a pressure control chamber supplied with fuel pressure from a fuel inlet and a drain passage formed in a valve body to change fuel pressure within the pressure control chamber, thereby bringing the needle valve into engagement with and disengagement from a spray hole. The fuel injector also has a first orifice disc and a second orifice disc installed within the valve body. The first orifice disc has formed therein a first orifice which provides a first flow resistance to fuel flowing from the fuel inlet into the pressure control chamber. Similarly, the second orifice disc has formed therein a second orifice which provides a second flow resistance smaller than the first flow resistance to the fuel flowing out of the pressure control chamber into the drain passage. The second orifice disc is disposed on the first orifice disc so that thicknesswise directions thereof coincide with each other.
