Abstract:
A fuel injection valve includes a main body having a nozzle hole and a compression chamber. The main body accommodates a compression unit for pressurizing fuel accumulated in the compression chamber. The fuel injection valve further includes a valve element being axially movable in the main body. The valve element includes a valve portion and a pressure-receiving portion. The valve portion is movable in an opening direction to open the nozzle hole in response to pressure of fuel being pressurized by the compression unit and applied to the pressure-receiving portion. A regulating unit is provided in the compression chamber for regulating movement of the valve element with respect to the opening direction.
