摘要： The present invention proposes a fuel injection valve for an internal combustion engine, comprising: a body (20) having a fuel channel (24) which extends substantially along the longitudinal axis of the body (20). Said body (20) comprises a bore (22) allowing to send an autofrettage medium for an autofrettage process, which extends angularly to the fuel channel (24) and in that the bore (22) has an angle (α) with the fuel channel (24) of about between 30° and 90° allowing the autofrettage medium to be directed and flowed through the bore (22) to the fuel channel (24) at a predetermined angle for eliminating erosion corrosion at the inner peripheral surface of the fuel channel (24). Further, the diameter of the first arm (28) and the second arm (29) of the bore (22) can be smaller than the diameter of the bore (22) allowing the autofrettage medium to be directed and flowed to the fuel channel (24) from the bore (22) for eliminating erosion corrosion at the inner peripheral surface of the fuel channel (24).

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.
