摘要： Fuel injector (1) for injecting fuel into a combustion chamber of an internal combustion engine having a nozzle needle (3) which is arranged longitudinally displaceably in a pressure space (6). The pressure space (6) can be filled with highly pressurized fuel. The nozzle needle (3) interacts as a result of its longitudinal movement with a nozzle needle seat (7) and as a result opens and closes at least one injection opening (8) into the combustion chamber. The longitudinal movement of the nozzle needle (3) is controlled by way of the pressure in a control space (10), it being possible for the control space (10) to be connected to a low-pressure space (30) by means of a control valve (5) which can be actuated by an actuator (2). The control valve (5) comprises a closing body (50) which can be moved by the actuator (2), a valve seat (12) and a closing spring (4), the closing body (50) interacting with the valve seat (12) in order to open and close a hydraulic connection from the control space (10) to the low-pressure space (30). The closing body (50) is pressed at least indirectly by the closing spring (4) against the valve seat (12). According to the invention, the closing spring (4) is configured as a wave spring.
摘要翻译：一种燃料喷射器（1），用于将燃料喷射到具有在压力空间（6）中纵向移位的喷嘴针（3）的内燃机的燃烧室中。压力空间（6）可以用高压燃料填充。喷嘴针（3）由于其纵向运动而与喷嘴针座（7）相互作用，因此打开和关闭至少一个喷射口（8）进入燃烧室。通过控制空间（10）中的压力来控制喷嘴针（3）的纵向运动，控制空间（10）可以通过以下方式连接到低压空间（30）可由致动器（2）致动的控制阀（5）。控制阀（5）包括可由致动器（2）移动的关闭体（50），阀座（12）和闭合弹簧（4），闭合体（50）与阀座以便打开和关闭从控制空间（10）到低压空间（30）的液压连接。关闭主体（50）至少间接地被关闭弹簧（4）压靠在阀座（12）上。根据本发明，闭合弹簧（4）构造为波形弹簧。
