    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: 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: The invention relates to a valve arrangement (2) for metering a fluid medium into an exhaust line (22), comprising a valve seat (10) which acts together with a closing body (12) and in which a valve passage (14) is implemented, and a perforated disc (6) that is disposed downstream of the valve seat, closes off the valve passage, and has at least one axial hole (8) in the area of the valve passage through which the fluid medium can be injected into the exhaust line (22). The valve arrangement further comprises a connecting flange (16) for connecting the valve arrangement (2) to the exhaust line (22) in a fluid-tight manner, wherein the perforated disc (6) extends from the valve passage to the connecting flange and is implemented such that said perforated disc seals the connecting flange against the exhaust line in a fluid-tight manner in the installed state. A separate seal is thus no longer required, because the perforated disc performs the sealing function.

    摘要: The invention relates to a device (40) for reducing pollutants, in particular nitrogen oxides, in an exhaust gas flow of an internal combustion engine, comprising a reducing agent (46), in particular a urea-water solution, which is stored in a storage tank (42), a metering module, in particular a nozzle (68), for injecting the reducing agent (46) into the exhaust gas flow, and a pump (56, 100) for delivering the reducing agent (46) from a suction point (62) in the storage tank (42) to the metering module via lines (58, 66). According to the invention, the pump (56, 100) lies beneath a reducing agent level (44) in the storage tank (42), and a non-return valve is provided. As a result of the non-return valve, the device (40) is prevented from refilling with the reducing agent (46) after the reducing agent (46) is completely sucked back from the device (40) after shutting off the internal combustion engine, in particular after extended idle times of the internal combustion engine. In a first embodiment, the non-return valve is a filter (64) that is formed with a plurality of screens (80, 82, 84, 86) which are connected one behind the other, which have a special microstructure, and which are formed with a plastic material. In the case of a second embodiment, the non-return valve is formed with a hermetically sealing valve (158) which is heavily preloaded by a spring force in particular and which is directly integrated into the pump (100) that is necessary for delivering the reducing agent (46) in the device (40).
