发明名称 FUEL INJECTION VALVE
摘要 <p>An fuel injection valve (1A) has: a needle (3) housed in a valve body (2) in a reciprocable manner; an injection hole plate (4) attached to a front end portion of the valve body (2), the plate (4) having an injection hole connecting an inside and an outside of the valve body (2); and a valve sheet (6) which the needle (3) is attached to or detached from so as to close or open a fuel flow path (10) that reaches the injection hole (7) of the injection hole plate (4) through an outer circumference of the needle (3). The injection hole plate (4) has a recessed portion (15) dented in an axial direction of the needle (3) so as to cause fuel flowing toward the injection hole (7) through the valve sheet (6) to descend lower than a height of an inlet port (20) of the injection hole (7) and then, to turn to ascension so as to reach the inlet port (20) of the injection hole (7) on the injection hole plate (4).</p>
