    • A fuel injection valve is provided with a main body and a valve member. The main body has a fuel passage and a fuel injection opening formed at the downstream-end of the fuel passage. The valve member is provided in the fuel passage. The valve member is configured to move between a first position in which the valve member closes the fuel injection opening and a second position in which the valve member opens the fuel injection opening. The fuel injection valve is further provided with a compression spring disposed in the fuel passage and a spring pin. The compression spring restrains the valve member toward the first position. The spring pin is pressedly inserted into the fuel passage for keeping the compression spring in the fuel passage. A surface of the spring pin has a resistance against sulfur.
    • 燃料喷射阀设置有主体和阀构件。 主体具有形成在燃料通道的下游端的燃料通道和燃料喷射开口。 阀构件设置在燃料通道中。 阀构件构造成在阀构件关闭燃料喷射开口的第一位置和阀构件打开燃料喷射开口的第二位置之间移动。 燃料喷射阀还设置有设置在燃料通道中的压缩弹簧和弹簧销。 压缩弹簧将阀构件限制到第一位置。 弹簧销被压入插入燃料通道中以将压缩弹簧保持在燃料通道中。 弹簧销的表面具有耐硫的性能。
