Abstract (en)
[origin: WO2020260285A1] The fuel injection valve (10) has a hydraulic control device (72) for controlling the axial movement of the injection valve member (56). The stem (76) of the intermediate valve member (78) of mushroom-shaped configuration of the intermediate valve (83) is guided in a sliding fit in the guide recess (74) of the intermediate part (66). The intermediate valve member (78) separates the control chamber (70) from the valve chamber (44) apart from the throttle passage (90) which is configured on the intermediate valve member. Furthermore, the throttle inlet (96) which is connected to the high pressure chamber (26) is configured on the intermediate valve member (78).
