    An injection valve comprising a hollow casing containing an electromagnetic winding connected to a source of electric pulses, an armature in the casing near the winding, a likewise hollow nozzle held by the casing so as to extend therein for a length defined by the geometrical requirements of the intake manifold so as suitably to position the fuel discharge aperture at the front end of the manifold, a closure means having a first end secured to the armature, an external surface coupled to the inner surface of the nozzle, to guide the travel of the closure means, and a second end comprising a conical part adapted to come in contact with a conical seat formed in the nozzle immediately upstream of a bore and bearing a fuel-atomizing deflector which co-operates with the bore in the nozzle to define the fuel discharge aperture, the conical part forming a seal when, under the action of a resilient force, it is in contact with the conical seat whereas it opens the discharge aperture under the action of the magnetic field so as to allow fuel to escape from the valve, the valve also comprising end-of-travel means adapted to limit the opening travel of the closure means, and a pipe system through which the fuel, after being sent to the valve under pressure by the supply device, travels from the inlet to a region upstream of the sealing seat and between the outer surface of the closure means and the inner surface of the nozzle; said pipe system, at the region upstream of the sealing seat, being formed with a number of bores 37, the axis of which has a considerable component parallel to the central longitudinal axis of the injector.

    2. The injector according to claim 1, characterized in that the elastic means is made in the form of a spring placed between the end of the pipeline
    and a transverse wall of the locking means. ..
    3. The nozzle on the PP. 1 and 2, this is due to the fact that the sprayer and the locking means are equipped with two pairs of guide surfaces located one opposite the other, separated by grooves made on the inner surface of the sprayer and the outer surface of the stop means, and a spring. located in the area between the pairs of guide surfaces.
    FIELD: motor.
    A known nozzle for an internal combustion engine, comprising a hollow body, an electromagnetic winding placed therein, axially movable bark of a tubular form, a spreader with a nozzle, made along the nozzle axis, fixed on the crust and mounted in the atomizer a movable locking means with a conical seating surface , with a pin installed in the nozzle and a cavity delimited from the seating surface by a transverse wall, an elastic means acting on the locking means in the axial direction, against the positive effect of the electromagnetic force of the winding, and the fuel supply pipe, placed along the axis of the electromagnetic winding and the tubular core inside the cavity of the locking means
    The disadvantage of this nozzle is increased fuel consumption.
    The purpose of the invention is to increase the injection efficiency.
    This goal is achieved by the fact that channels are arranged in the transverse wall of the Valve, the longitudinal axis of which is at an angle Less than with the idol axis of the valve, the elastic means are in the form of a spring placed between the end of the pipeline and the transverse wall of the valve, the spray gun and the valve The tool is equipped with two. pairs of one against the other guide surfaces separated by grooves made on the inner surface of the dispenser and the external surface of the locking means, and the spring is located in the area of the slide with pairs of guide surfaces.
    FIG. 1 shows the structural scheme of the proposed nozzle; in fig. 2 - the same, cross section in a zone of locking means.
    -The nozzle contains a hollow body 1 placed therein electromagnetic winding 2 ,. axially movable bore 3 of a tubular shape, a dispenser 4 with a nozzle 5, made along the nozzle axis, mounted on the bark 3 and mounted in the dispenser 4 movable locking means 6 with a conical seating surface 7, installed in the nozzle. 5 with a pin 8 and a cavity 9 delimited from the seating surface 7 by a transverse wall 10, elastic means 11 acting on the locking means b in the axial direction opposite to the action of the electromagnetic force of the winding 2, and the fuel supply pipe 12 placed along the axis of the electromagnetic winding 2 and the tubular core 3 inside the cavity 9 of the locking means b. In the transverse wall 10 of the locking means b, the channels 13 are made; the longitudinal axis of the key is at an angle of less than 90 ° with respect to the prodol axis of the locking means b. The elastic means 11 is made in the form of a spring placed between the end of the pipeline 12 and the transverse wall 10 of the locking means b. The nebulizer 4 and the locking means b are provided with two paraglides located opposite each other of the guiding surfaces 14 and 15, separated by grooves 16 and 17, made on the inner surface of the nebulizer 4 and the outer surface of the locking means 6, and the spring 11: between pairs 14 and 15 of the guide surfaces.
    ; The nozzle operates as follows ..: The fuel from the pump under pressure is supplied to the fuel supply pipe. The conductor 12 and the cavity 9 of the locking means 6. In the absence of voltage in the electric winding 2, the locking means 6 are kept in the closed position by the action of the spring 11. enters the engine of internal combustion. In ms, the dent polach strains | Neither the winding 2 under the influence of electr. Magnetic force tubular measles 3 is attracted to the impact of the spring 11, the nozzle 5 is opened and the fuel through the channels 13
    enters the engine BHyTpeif iero combustion. Regulation flow toP. The production is carried out with the help of a pin. 8. .
    Thus, the proposed Kong jet nozzle provides improved injection efficiency.
