摘要： A measuring body is provided in a fluid path between a pump and a fuel injection valve, a flow amount for which is measured. An inner space of the measuring body is divided into a first and a second fluid chambers by a partitioning wall, wherein the first and second fluid chambers are, respectively, operatively connected to the pump and the fuel injection valve. A movable member (float) is slidably inserted into a through-hole formed in the partitioning wall, so that both ends are respectively exposed to the first and second fluid chambers. When the fuel injection is carried out by the fuel injection valve, the fluid in the second fluid chamber is decreased corresponding to the amount of injected fluid, and thereby the float is moved in a direction from the first to the second fluid chamber. The amount of the injected fluid is measured by detecting the movement of the float.
摘要翻译：测量体设置在泵和燃料喷射阀之间的流体路径中，其测量流量。测量体的内部空间通过分隔壁被分成第一和第二流体室，其中第一和第二流体室分别可操作地连接到泵和燃料喷射阀。可移动部件（浮子）可滑动地插入到形成在分隔壁中的通孔中，使得两端分别暴露于第一和第二流体室。当通过燃料喷射阀执行燃料喷射时，第二流体室中的流体相应于注入流体的量而减小，从而浮子沿着从第一流体室到第二流体室的方向移动。通过检测浮子的移动来测量注入流体的量。

摘要： A fluid injection valve has a valve body, a fixed core, a moving core, a coil and a valve element. The valve element slides together with the moving core to open and close a valve seat. The valve element has an annular connection portion at an axial end portion thereof to be connected and fitted to an inner circumferential face of the moving core. The valve element forms an inner space therein to open to the moving core. A side wall of the valve element has a notch thereon at a downstream side of the annular connection portion to form a communication passage between the inner space and an outer space outside of the valve element.
