| 摘要 |
The invention relates to a device for injecting fuel into the combustion chamber of an internal combustion engine. A control unit (1) is provided, which contains a housing chamber (4) that is continuously acted on with highly pressurized fuel by means of an inlet from a reservoir (common rail). The highly pressurized fuel is continuously present in the control chamber (6) of a control valve body (5) by means of an inlet throttle (7), wherein the control valve body (5) opens or closes a nozzle inlet (14) to an injection nozzle. The housing chamber (4) of the control unit (1) contains a thrust transmitting member (21) that delimits the control chamber (6), and the thrust transmitting member (21) is supported with a flat face (23) against the housing (2) and contains an outlet throttle (28) that pressure-relieves the control chamber (6) and can be opened by means of a servo valve (24).
