    • 专利摘要:
    A fuel injector, for internal combustion engines, having a nozzle needle supported in a nozzle body so as to be axially displaceable therein. The nozzle needle, which can be lifted off its valve seat by the pressure of fuel, has a throttling pin which, at least during part of its lift, projects below the valve seat into a bore centrally arranged in the nozzle body. The throttling pin has at least one control edge or flat portion which is shaped and oriented in such a way that the fuel spray direction and/or the fuel spray characteristic or pattern vary with the nozzle needle lift.

    (54) FUEL JET
    This invention relates to a motor structure. The fuel injector of the internal combustion engine is known, the body with a nozzle hole and the needle located in the body — with a sealing cone and a pin with a control edge at its end — are filled with a possibility of entering an orifice during the entire needle stroke 1. The disadvantage of this nozzle is that it does not provide for the regulation of the fuel jet over a wide range. The purpose of the invention is to regulate the fuel jet over a wide range. This goal is achieved by the fact that the control edge is made inclined to the axis of the nozzle or in the form of a flat face located on the pin on the side of the nozzle orifice. In addition, the aft face is formed on the cylindrical part of the Pin by its segment section, and the nozzle opening is partially filled with a blind for the entrance of the pin and provided with a passage located inclined to the Orsunka axis (T). FIG. 1 shows the structural scheme of the proposed spray gun in the closed position; in fig. 2 - the same, in a partially open position, on. FIG. 3 is the same in the open position in FIG. 4 - the same, with a control edge made in the form of flats; on . FIG. 5 shows section A-A in FIG. 4. The nozzle includes a housing 1 with a nozzle hole 2 and a needle 3 located in the housing 1 with a sealing cone 4 and a pin 5 with a control edge 6 made inclined to the nozzle axis or in the form of a flat 7 located on the cylindrical part of the pin 5 on the side of the nozzle holes 2 and formed by the segment segment of the pin 5. The nozzle hole 2 is partially deaf to the entrance of the pin 5 and provided with a passage 8 located obliquely to the axis of the nozzle. The nozzle works as follows. With increasing pressure supplied by the fuel pump, the needle 3 rises and the fuel enters the cavity of the housing 1 located by the sealing cone 4. With a slight lift of the needle 3 into the engine, the fuel enters through the annular gap between the nozzle orifice 2 and the stem 5. With the subsequent rise. Needles
