    摘要： In the valve, fuel, flowing down as a valve side flow along the side of the valve, further flows down toward an orifice plate through a fuel path which closes and opens upon forward and backward movement of the valve, and is injected as a mist from each orifice. The valve moves forward and backward by sliding on a valve surrounding portion through a guide portion constituted by plural sliding guides arranged between the valve and valve surrounding portion. Since the sliding guides are tapered from the valve to the surrounding portion, the side flow from the guide portion has a flow velocity distribution biased toward the surrounding portion.

    摘要： A fuel injection valve includes: a swirl chamber having an inner peripheral wall formed to be gradually increased in curvature toward a downstream side from an upstream side; a swirl passage, through which a fuel is introduced into the swirl chamber; and a fuel injection port opened to the swirl chamber, wherein the swirl chamber and the swirl passage are formed so that a side wall of the swirl passage connected to a downstream end side of the swirl chamber, or an extension thereof is made not to intersect a downstream side portion of the inner peripheral wall of the swirl chamber, or an extension thereof.
