摘要： PROBLEM TO BE SOLVED: To improve linearity in "actual injection amount versus injection command time period".SOLUTION: When a nozzle needle 43 exists at a full lift position, a nozzle high-pressure communication passage 433 and a cylinder high-pressure communication passage 441 are communicated, a fuel reserving chamber 413 and a needle control chamber 46 are kept in a communicated state through the nozzle high-pressure communication passage 433 and the cylinder high-pressure communication passage 441, and lowering of a pressure of the needle control chamber 46 is prevented. By keeping the pressure of the needle control chamber 46 to be a prescribed pressure or more, a valve closing state of a high-pressure control valve 48 is kept, and hunching of the high-pressure control valve 48 is prevented. Accordingly, dispersion in the position of the high-pressure control valve 48 in closing a discharge control valve 47, is eliminated, and further dispersion in a time period from the closing of the discharge control valve 47 to start of movement in the valve closing direction, of the nozzle needle 43 is eliminated, thus the linearity in "actual injection amount versus injection command time period" can be improved.
摘要翻译：要解决的问题：提高“实际喷射量与喷射指令时间段”的线性度。解决方案：当喷嘴针43存在于全升程位置时，喷嘴高压连通通道433和气缸高压连通通道 441连通，燃料储存室413和针控制室46通过喷嘴高压连通路433和气缸高压连通路441保持连通状态，并且降低针控制室的压力 46被阻止。通过将针控制室46的压力保持在规定的压力以上，能够保持高压控制阀48的关闭状态，并且能够防止高压控制阀48的冲击。因此，消除了在关闭排气控制阀47时在高压控制阀48的位置处的分散，并且在从排出控制阀47的关闭到关闭方向的开始运动的时间段内进一步分散，因此可以提高“实际喷射量与喷射指令时间段”之间的线性。

摘要： PROBLEM TO BE SOLVED: To achieve excellent response and stable fuel injection characteristics.SOLUTION: A fuel injection device 10 includes a cylinder 80 that defines a pressure chamber 34 at an end portion of a nozzle needle 90. A floating plate 100 as a control member is placed in the cylinder 80. A cutout portion 105 and multiple grooves 106 are formed in the floating plate 100. The cutout portion 105 and the grooves 106 cause a gap between a large-diameter inner circumferential surface 81 and an outer circumferential surface 102 to communicate with the pressure chamber 34. The cutout portion 105 and the grooves 106 reduce a contact surface between the cylinder 80 and the floating plate 100 and divide the contact surface into multiple island portions. As a result, it is possible to reduce the contact surface, and excellent response and stable fuel injection characteristics are obtained.
