摘要： The invention relates to an injector for injecting fuel into combustion chambers of internal combustion engines, in particular a common rail injector. The injector has a high-pressure region and a valve element which is axially adjustable between a closed position and an open position in which the flow of fuel is enabled. According to the invention, it is provided that the valve element includes a first partial element and at least one separate second partial element, which partial elements are hydraulically coupled to one another by a coupler chamber. The coupler chamber is hydraulically connected only in one axial direction to the high-pressure region of the injector.

摘要： The invention relates to a fuel injector with an injector housing which has a high-pressure fuel connection which is connected to a central high-pressure fuel source outside the injector housing, and with a pressure chamber within the injector housing. According to the pressure in a coupling chamber, fuel under a high pressure is injected from the pressure chamber into a combustion chamber of an internal combustion engine when a nozzle valve opens. The nozzle valve has a combustion chamber-remote end with a control pressure surface which is acted upon in the coupling chamber by the coupling chamber pressure. In order to create a fuel injector which can be produced inexpensively, the nozzle valve has at least one low-pressure surface which is averted from the combustion chamber and acted upon with low pressure.

The movement of the nozzle needle (4) can be controlled by a control valve which co-operates with a control chamber (6). The control valve comprises a valve needle (7) which is guided back and forth and can be moved in relation to a sealing seat (8) in order to ventilate the control chamber (6) in a fuel return (8) when the valve needle (7) is lifted from the sealing seat (8). The valve needle (7) has a differential surface which enables the needle to be subjected to a fuel pressure and held in the direction of the sealing seat (8).

摘要： A fuel injector with a direct needle control for an internal combustion engine, having an actuator, a hydraulic booster, and a nozzle needle guided in a nozzle body and acting on a nozzle needle sealing seat. The hydraulic booster includes a booster piston connected to the actuator and a nozzle needle booster piston connected to the nozzle needle; a booster chamber in the form of an actuator coupler chamber is associated with a pressure surface of the actuator booster piston; and depending on the pressure in the actuator coupler chamber, the nozzle needle is lifted away from the nozzle needle sealing seat, thus initiating an injection. In addition to the actuator booster piston, a control element is provided that is able to execute a stroke motion, is hydraulically coupled to the actuator coupler chamber by means of a first control surface, and is associated with a control chamber by means of a second control surface. The actuator booster piston has a second pressure surface, which, as an additional control surface, is associated with the control chamber.

摘要： A fuel injector having a pressure booster whose booster piston separates a working chamber, which is continuously acted on with fuel by means of a pressure source, from a differential pressure chamber that can be pressure-relieved; a pressure change in the differential pressure chamber occurs via an actuation of a servo-valve whose control chamber can be pressure-relieved by an on/off valve that also opens or closes a hydraulic connection of the differential pressure chamber to a first return on the low-pressure side. In the deactivated state of the pressure booster, a first sealing seat seals a return on the low-pressure side off from a high-pressure region of the servo-valve, which region is comprised of the control chamber, a first hydraulic chamber, and a second hydraulic chamber.

摘要： A method for triggering a fuel injector via an on/off valve and a control valve that actuates it. The fuel injector has a pressure booster whose piston parts separate a working chamber from a differential pressure chamber. Via a compression chamber of the pressure booster, a nozzle chamber of the fuel injector can be acted on with highly pressurized fuel. The working chamber of the pressure booster communicates continuously with a common rail. During the main phase in which fuel is injected into the combustion chamber of an internal combustion engine, the control valve that actuates the on/off valve is triggered once or multiple times so that the maximum pressure level occurring at the combustion chamber end of a one-part or multipart injection valve member falls below the maximum achievable pressure level.
