摘要:
PROBLEM TO BE SOLVED: To effectively prevent injection of fuel from an injection hole from being influenced by a slide guide in a fuel injection valve having the slide guide guiding forward/backward movement of a valve element for opening/closing a valve.
SOLUTION: The fuel injection valve is constructed so that fuel flowing down as a valve element side face flow F along the side face of the valve element 15 passes through a fuel passage 20, which is opened/closed by forward/backward movement of the valve element, toward an injection hole plate 19 to be sprayed from the injection hole 35. The valve element is moved forward/backward by sliding against a valve element surrounding part 17, and the sliding of the valve element is carried out via a guide part 18 formed by aligning a plurality of slide guides 41 between the valve element and the valve element surrounding part. In this fuel injection valve, when the slide guide is formed into a shape tapering off gradually from the valve element side to the valve element surrounding part, a deviated flow rate distribution PD biased to the valve element surrounding part is generated in the valve element side face flow having passed through the guide part.

要解决的问题:为了有效地防止来自喷射孔的燃料的喷射受到具有导向用于打开/关闭阀的阀元件的向前/向后运动的滑动引导件的燃料喷射阀中的滑动引导件的影响。 解决方案:燃料喷射阀构造成使得沿着阀元件15的侧面作为阀元件侧面流动F流动的燃料通过燃料通道20,燃料通道20通过向前/向后运动打开/关闭 的阀元件朝向从喷射孔35喷射的喷射孔板19.阀元件通过滑动抵靠围绕部件17的阀元件而向前/向后移动,阀元件的滑动通过 引导部分18,其通过在阀元件和阀元件周围部分之间对准多个滑动引导件41而形成。 在该燃料喷射阀中,当滑动引导件形成为从阀元件侧逐渐向阀元件周围部逐渐变细的形状时,在阀元件侧产生偏置于阀元件周围部的偏离流量分布PD 已经穿过引导部分的面部流动。 版权所有(C)2008,JPO&INPIT
