摘要： Disclosed is a fuel injection valve for internal combustion engines, having a valve body in which a hollow valve needle is disposed longitudinally displaceably in a bore. The hollow valve needle, on its end toward the combustion chamber, has a conical valve sealing face, which cooperates with a conical valve seat disposed on the end of the bore toward the combustion chamber. A longitudinal bore is embodied in the hollow valve needle, and a valve needle is disposed in it and, with a valve contact face embodied on its end toward the combustion chamber, likewise cooperates with the valve seat. The tip of the hollow valve needle toward the combustion chamber is formed by a chamfer.

摘要： A fuel injection system for internal combustion engines, having a high-pressure accumulation chamber, which contains high-pressure fuel, and at least one fuel injection valve, which is connected to the high-pressure accumulation chamber. The fuel injection valve can inject the highly pressurized fuel through injection openings into a combustion chamber of the engine. The fuel injection valve has a control chamber, which is defined by a longitudinally mobile piston and is operationally connected to the fuel injection valve so that the injection cross section of the fuel injection valve is controlled as a function of the hydraulic pressure in the control chamber. A low-pressure accumulation chamber is provided, which can be connected to the control chamber, in which a predetermined fuel pressure is maintained in the low-pressure accumulation chamber that is lower than the pressure in the high-pressure accumulation chamber.

摘要： A fuel injection valve for internal combustion engines, having a housing with a bore inside it that contains a longitudinally sliding outer valve needle which in turn contains a longitudinally sliding inner valve needle and the end of each valve needle oriented toward the combustion chamber controls at least one injection opening. The pressure in a control pressure chamber at least indirectly exerts a closing force on the outer valve needle and the pressure in a control pressure chamber at least indirectly exerts a closing force on the inner valve needle. The housing contains a control valve that has a valve chamber and a valve element contained in it, wherein the valve chamber has a connection to the leakage oil chamber, a continuously open connection to the control chamber and a connection to the control pressure chamber. The valve element can move between a end position, the valve element closing the connection to the leakage oil chamber and opening the connection to the control pressure chamber and a second end position, closing the connection to the control pressure chamber and opening the connection to the leakage oil chamber.

摘要： A fuel injection valve for internal combustion engines, having a valve member that emerges outward from the valve body. At least two rows of injection ports one above the other are provided on the valve member, in the outward-oriented opening stroke of the valve member the injection parts are uncovered in secession. A two-stage hydraulic stroke stop, which limits the opening stroke travel of the valve member is embodied as a hydraulic damping chamber with openable relief. This relief is effected via at least two polished sections on the valve member which are openable in succession during the opening stroke motion of the valve member. At least one of the polished sections is connected to a low-pressure chamber, via a relief conduit containing a valve.

摘要： In an injection nozzle for a fuel injection system, the opening stroke of the nozzle needle is to be limited selectively, so that different injection cross sections can be employed. To that end, the injection nozzle is provided with a nozzle body, a nozzle needle displaceable in the nozzle body, two groups of injection ports, which are uncovered as a function of an opening stroke of the nozzle needle, a piston that is connected to the nozzle needle, a stop chamber in which the piston is disposed and which is provided with an outlet, and a control valve that can open and close the outlet of the stop chamber, as a result of which the stroke of the piston in the stop chamber and thus the opening stroke of the nozzle needle can be selectively limited.

摘要： A fuel injection valve for internal combustion engines, having a valve member, which is guided axially displaceably in a bore of a valve body. An end toward the combustion chamber and that protrudes from the bore has a valve sealing face with which the valve member cooperates, to control an injection cross section, with a valve seat face on the valve body. A stroke stop face which is stationary relative to the valve body and with which the valve member comes into contact with a bearing face after traversing an outward-oriented maximum opening stroke distance, and the stroke stop face is disposed on an end face of an axially split stroke stop ring which is surrounded by a support ring. A valve spring urges the valve member in the closing direction and is supported stationary on the valve body via a spacer ring and an intermediate member. The support ring surrounding the stroke stop ring is supported stationary relative to the valve body and constantly contacts the spacer ring.

摘要： A fuel injection nozzle for internal combustion engines that has a nozzle body with a valve seat disposed on the combustion chamber end and an outwardly-opening valve needle with a closing head, which has a closing cone that works together with the closing valve seat. At least one injection port is disposed in the closing head at an angle with respect to the axis of reciprocation of the valve needle, and is opened by a control edge on the nozzle body depending on the inlet pressure of the fuel. In order to minimize any deflection of the injection stream flowing out of the injection port relative to the alignment of the injection port, the port is divided into at least two parallel conduits, which are separated from each other by a dividing wall and which upon the opening stroke of the valve needle are unblocked one after the other by the control edge.

摘要： A fuel injection nozzle for internal combustion engines with direct injection including a nozzle body and an outward-opening valve needle with a closing head, in which outward-oriented injection ports are disposed. In order to form exact oriented fuel streams from the injection onset on, the cross section of the stream is controlled by the valve needle as a function of its stroke. The injection ports have a sharp control edge with a sharp control edge on the nozzle body which determines the injection cross section, and a sealing seat line formed by a hollow frustoconical valve seat on the nozzle body and a frustoconical valve cone on the nozzle needle, with a radially inner annular edge. The annular edge is disposed on an annular body secured to the valve needle and is aligned with the control edge of the injection ports in the injection direction of the injection ports. The annular body is secured to the end of the nozzle needle toward the combustion chamber either nonpositively or positively.

摘要： A fuel-injection nozzle for internal combustion engines having plurality of lip elements on a nozzle tube, the edges are adjacent to each other. The lip elements form an obtuse cone and are held together under a high pre-stressing pressure by a clamping sleeve and an end cap. Pressure build-up in the interior chamber of the nozzle tube elastically expands the lip edges, in which case gaps are created, which form flat spray streams through which fuel is sprayed into the combustion chamber of the engine. When the fuel pressure in the interior chamber subsides the lip edges close to prevent any dirt from entering the slits.

The valve member has a sealing face with which the sealing face cooperates with a valve seat on the valve body. The valve body has at least one injection opening, which can be uncovered in a course of a valve member opening stroke motion only after a certain idle stroke has been excited and the valve sealing face has lifted from the valve seat. The injection opening is provided in the wall of the valve body and an inlet opening of the injection opening is closable by the valve member.
