摘要： PROBLEM TO BE SOLVED: To reduce a force acting on a valve element by a flow of fuel in an injector used for an internal combustion engine.
SOLUTION: A tip of a valve element or a valve seat surface of a fuel injection valve is formed to have a larger gap between the tip of the valve element and the valve seat surface formed with a conical surface than a gap made by connecting a cylindrical surface of the valve element to a spherical surface forming the valve seat with an arc. A cross sectional area of a flow passage outside the valve element abruptly increases starting from the valve seat surface. The abrupt increase reduces portions of the valve element subjected to pressure due to decrease in static pressure, thus reducing force acting on the valve element.
