摘要： A fuel injection system for internal combustion engines, has a distributor tube and a high-pressure pump which is driven as a function of engine rpm and serves to generate the fuel pressure and fuel throughput required in the distributor tube in the applicable operating state of the engine, and also has a fuel metering unit, which is assigned to the high-pressure pump and is based on an electromagnetically actuated regulating valve. The fuel metering unit is disposed in the high-pressure pump, and the outlet of the regulating value discharges into the low-pressure region of the high-pressure pump. The inlet of the regulating valve communicates with the compression side of a prefeed pump. The regulating valve has a valve piston, which is actuated—into the opening position—by a compression spring and which is actuatable counter to the spring force—into the closing position—by an armature bolt of the electromagnet. Valve piston has at least one and preferably more radial control openings, which are in operative communication with the intake side of the high-pressure pump.

摘要： A fuel injection system for internal combustion engines, has a distributor tube and a high-pressure pump that is driven as a function of engine rpm and that serves to generate the fuel pressure and throughput required in the distributor tube in the applicable operating state of the engine. The system also includes a fuel metering unit, which is associated with the high-pressure pump and includes a regulating valve which is actuated electromagnetically. The fuel metering unit is disposed in the high-pressure pump, and the outlet of the regulating valve discharges into the low-pressure region of the high-pressure pump.

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： 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： A fuel injection system has a low-pressure pump for withdrawing fuel from a tank and a high-pressure pump, which is supplied by the low-pressure pump and has camshaft-actuated pump elements. An on-off valve is connected on the inlet side to the pressure side of the low-pressure pump and on the outlet side, is connected on the one hand to a camshaft chamber of the high-pressure pump and on the other hand, is connected to the suction side of the low-pressure pump. At a first pressure threshold, a spring-loaded valve piston of the on-off valve opens a connection between the low-pressure pump and the camshaft chamber and at a relatively higher second pressure threshold, opens a connection between the pressure side and the suction side of the low-pressure pump. A throttle bore in the bottom of the valve piston serves to ventilate the low-pressure system.
