摘要： A fuel injection valve for internal combustion engines having a valve body in which a bore is embodied, a valve seat face, at least one injection opening embodied on the end toward the combustion chamber of the bore, and at least one injection opening connecting the bore with the combustion chamber of the engine. A nozzle needle is longitudinally displaceably guided in the bore and on its end toward the combustion chamber it has a sealing face, which cooperates with the valve seat face and thus controls the at least one injection opening. The nozzle needle has a central longitudinal bore, in which an inner needle is disposed that is fixed immovably relative to the valve body. The nozzle needle is guided over at least part of its length on the inner needle, so that the nozzle needle is kept exactly centrally in the bore at all times.

摘要： A solenoid valve for controlling a fuel injector of an internal combustion engine, including an electromagnet, a movable armature featuring an armature plate and an armature pin, as well as a control valve member, which is moved with the armature and cooperates with a valve seat, for opening and closing a fuel discharge passage of a control pressure chamber of the fuel injector, the armature plate being supported on the armature pin, so that it is slidably movable in the closing direction of the control valve member under the action of its inertial mass, against the elastic force of a return spring that acts upon the armature plate; and including a hydraulic damping device which permits damping of a post-oscillation of the armature plate during its dynamic sliding on the armature pin. To facilitate the assembly and reduce a disadvantageous post-oscillation process of the armature plate, it is proposed for the return spring to be braced, with its end facing away from the armature plate, against a supporting piece, which is mounted on and moved with the armature pin and which, at the same time, constitutes a part of the damping device.

摘要： Disclosed is a fuel injection valve including a valve body and a bore, embodied as a blind bore, whose bottom face is oriented toward the combustion chamber, and a conical valve seat having at least one injection port is disposed, is embodied on the bottom face. In the bore, a pistonlike valve member, which is longitudinally displaceable counter to a closing force, is disposed and has a valve member tip, which in the closing position of the valve member comes to rest on the valve seat. A first conical face and a second conical face, disposed toward the combustion chamber toward the first conical face, are embodied on the valve member tip, and the cone angle of the first conical face is smaller than the cone angle of the valve seat, which in turn is smaller than the cone angle of the second conical face. One annular groove is embodied between the first conical face and the second conical face, and an additional encompassing annular groove is disposed on the second conical face and at least partly coincides with the injection ports in the closing position of the valve member, so as to supply all the injection ports uniformly with fuel even if the valve member is off its axis.

摘要： Disclosed is a fuel injection system, in particular a common rail system, for fuel delivery in internal combustion engines, in particular diesel engines of commercial vehicles, with a low pressure circuit in which at least one low-pressure feed pump supplies fuel from a fuel tank to a high-pressure pump which supplies the highly pressurized fuel to a central high-pressure fuel reservoir. In order to simplify the ventilation of the low-pressure circuit, a device is provided for intentionally decreasing the pressure in the low-pressure circuit.

摘要： An injector, especially for common rail injection systems of Diesel engines, has a nozzle needle, a control piston for actuating the nozzle needle, a valve that actuates the control piston and that is triggered by via an outlet throttle and an inlet throttle, and a hydraulic stop for the control piston, such that the flow from the inlet throttle to the outlet throttle at the narrowest cross section can additionally be throttled. The control piston is embodied conically on its offset top side oriented toward the outlet throttle or the inlet throttle.
