    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 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 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 valve for internal combustion engines, with an outward-opening valve member which, at one end projects out of a guide bore in a valve body. The valve has a valve head which acts as a closing member and on which is arranged a sealing face that cooperates with a valve seat on the valve body and which forms a sealing edge. For a variable injection cross section, a sleeve is attached onto the valve member on the region of the valve member located near the valve-member head, in which sleeve are provided a plurality of rows of injection orifices which can be opened in succession with an increasing opening stroke of the valve member. In order to allow a reliable and sealing guidance of the valve member, an inflow duct to the injection orifices is designed as a recess in the valve-member shank, in such a way that a web region guiding and sealing off the valve member in the sleeve remains.

    摘要: The invention sets forth a fuel injection valve for internal combustion engines, having a valve body and an expansion sleeve that cooperates with the valve body. A pressure chamber is defined between the expansion sleeve and the valve body into which a high-pressure conduit discharges which can be made to communicate with an injection cross section into the combustion chamber of the engine via an opening cross section, openable at high pressure, between the expansion sleeve and the valve body. The cup-shaped expansion sleeve is slipped onto the circumferential jacket face of the valve body and braced axially against the valve body; a portion of the expansion sleeve is embodied as a fastening element on the valve body.

    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.
