摘要： A fuel injector has a swirl generator located downstream from a valve seat. A fuel injection hole is connected to a downstream side of the swirl generator. The swirl generator includes a swirl chamber having an involute or a spiral shape and the fuel injection hole bored at a bottom or the swirl chamber and a swirl generation use passage connected to the upstream side of the swirl chamber for introducing fuel into the swirl chamber. The bottom of the swirl chamber is provided with a step height so as to make a level difference in which the bottom of the swirl chamber is lower than a bottom of the swirl generation use passage, and the step height is formed at a position where fuel flowing into the swirl chamber from the swirl generation use passage meets fuel turning in the swirl chamber.

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.
摘要翻译： 在阀门中，作为阀侧流动的燃料沿着阀的侧面流动，进一步通过燃料路径朝向孔板流动，该燃料通道在阀的向前和向后运动时关闭并打开，并以雾状喷射 从每个孔。 阀通过由布置在阀和阀周围部分之间的多个滑动引导件构成的引导部分在阀周围部分上滑动而前后移动。 由于滑动导向件从阀到周围部分是锥形的，所以来自引导部分的侧流具有偏向周围部分的流速分布。

摘要： A fuel injection valve has a valve body, a valve seat member having a valve seat and an opening portion formed at a downstream side of the valve seat member, a swirl chamber providing swirl to fuel, an orifice nozzle formed at a bottom of the swirl chamber and jetting the fuel, a communication conduit connecting the swirl chamber and the opening portion of the valve seat member, and a fuel inflow prevention wall provided at a connecting area between the communication conduit and the swirl chamber. The fuel inflow prevention wall is formed so as to prevent an incoming fuel from the communication conduit from directly flowing into the orifice nozzle and to suppresse a collision between a flow of the fuel that swirls and comes to the connecting area and a fuel flow coming from the communication conduit.
