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 device for transferring a thrust, a fuel injection valve with such a device, and a method for manufacturing such a thrust transferring device. To transfer the thrust of an actuator, especially in an injection valve, mechanical tappets are used, which have substantially the shape of a cylinder whose defining surfaces are substantially triangular, with the corners rounded. By the great width of the tappet, broad contact areas are created so that friction during the transfer is reduced.

摘要： A fuel injection valve for internal combustion engines with a valve member which is displaced in a bore in a valve body by the fuel pressure, counter to the action of a closing spring. The valve body has at a combustion-space end, a valve head which on a side which faces the valve body is arranged a sealing surface which interacts with a valve seat provided on the combustion-space end of the valve body, forming a sealing cross section, and including injection apertures which permit a flow of fuel from a pressure space in the valve body to the combustion space of the internal combustion engines and has an aperture cross section which can be varied as a function of the stroke of the valve member. According to the invention, those parts which seal off the injection valve from the outside and those parts which form the aperture cross section of the injection openings are geometrically separated from one another, the sealing cross section which closes the valve off from the outside being arranged downstream, as seen in the injection direction, of the variable aperture cross section, which is situated radially to the inside.

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 a nozzle body with a valve seat disposed on a side of the combustion chamber of the internal combustion engine and an outwardly opening needle valve with a closing head that has a closing cone that cooperates with the valve seat. At least one outwardly oriented injection hole is disposed in the closing head that is supplied with fuel via a supply conduit from a pressure chamber. The supply conduit is oriented axially with respect to the injection hole and changes over into this injection hole in a funnel shape. Its width corresponds approximately to the length of the injection hole. The injection hole and supply conduit extend at an acute angle a to the longitudinal axis of the closing head that is adapted to the combustion chamber of the internal combustion engine. The intake of the supply conduit is located in a face end of the closing head remote from the end on the side of the combustion chamber.

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.

In the fuel injection valve a damping chamber (35) is provided, which damps the stroke motion of the valve member (11) in the opening direction and moreover enables shaping of the course of injection.
