Abstract:
A fuel injection valve includes a housing having a wall surface on an opposite side of the nozzle hole. A fuel passage opens in the wall surface, and communicates with a nozzle hole through a nozzle cavity. The nozzle cavity accommodates a valve element. A cylinder is substantially in contact with the wall surface at one end, and slidably accommodating one end of the valve element. The cylinder partitions the nozzle cavity substantially into a fuel accumulator chamber and a pressure control chamber. The fuel accumulator chamber accumulates fuel supplied from the fuel passage. The pressure control chamber accumulates fuel for manipulating the valve element. The cylinder has an outer wall defining a deflecting surface for radially outwardly deflecting fuel flowing from the fuel passage.
