    The invention relates to a diesel fuel system and improves the accuracy of controlling the beginning and end of the fuel supply. The device comprises a housing 1 with a cavity 2, a valve 3 with a saddle 4, a high-pressure channel 5 with an injection valve 6, a discharge channel 7 connected by a connecting channel 8 with a channel 5, a spring 9, a hammer 10 of valve 3, an electromagnet 11 of the hammer 10, a second connecting the channel 12 and the second valve 13 with a spring 14. The connecting channel 12 is made in the form of an axial window 15 having a transverse window 16. In the housing 1, an annular cavity 17 is provided. The valve 13 is provided with a groove 18 interacting with the transverse windows 16 and 19 and connected with a connecting element 20 with a head 21, bark 22 and an electromagnet 23. The fuel supply to the nozzle occurs during the pump discharge, when channel 5 is disconnected from branch line 7 by means of valves 3 and 13. The end of supply is determined by the moment when valve 3 is detached from seat 4, after which fuel is bypassed to branch line 7. The start of the feed is determined by the moment of separation of the transverse windows 16 and 19 by the valve 13. 10 Cp f-ly, 1 ill.

    1, an annular cavity 17 is formed 17. The valve 13 is provided with a groove 18, interactions top; nm with transverse windows 16 and 19, and a connecting element 20 with a head 21, a bore 22 and an electromagnet 23 connected to it the discharge stroke of the pump when channel 5 is disconnected from one
    Channel 7 with the help of valves 3 and 13. The end of the supply is determined by the momehfTOM of the valve 3 being separated from the seat 4, after which the fuel is bypassed into the exhaust channel 7. з, п. ф-л, I Il.
     The invention relates to engine construction and is intended for use in diesel fuel systems.
    The aim of the invention is to improve the accuracy of controlling the start and end of the fuel supply.
    The drawing shows a structural diagram of the device.
    The device includes a housing 1 with an axial cavity 2, a valve 3 installed in the latter with a sliding gate element, a saddle 4 of the closing element 3 in the cavity 2, a high-pressure channel 5 connecting the injection fuel pump with the injection valve 6. bypass fuel channel 7 for draining fuel , a connecting channel 8 for communicating a high-pressure channel 5 with a diversion channel 7, a spring 9 for setting the locking element 3 in the locking position and a preloaded striker MO having an interlocking executive Agnita vto nonny 11 and to cooperate with a locking element 3. The device is further provided with a second connecting channel 12 formed between the high-pressure 5 and the branch channels 7 and the second valve 13 with a locking element for controlling the closure and opening of the second channel 12 soedintelnogo.
    The second valve 13 is installed in the second connecting channel 12. The valves 3 and 13 are arranged coaxially with respect to each other. The second valve 13 is equipped with a spring 14 and an actuating unlocking solenoid. The second connecting channel 12 is made in the form of an axial window 15 placed on the first valve 3 and having at least one transverse

    New window 16 in the zone of the exhaust channel 8 In case 1, an annular cavity 17 is made, which is connected through the lateral window 16 to the outlet channel 8. The second valve 13 is made H with a diameter equal to the diameter of the axial cavity 2 of the first valve 3, and on the outside of the second valve 13, a groove 18 is made, the length of which is at least equal to the distance between the transverse windows 16 and 19 of the first valve. The end surface of the groove 18 is designed as a control edge of the second valve 13. The springs 9 and 14 are placed on one side of the valves 3 and 13 coaxially one to the other. The valve is provided with an associated connecting element 20 with a head 21, a bore 22 and an electromagnet 23.
    The device works as follows.
    When the fuel is supplied by the pump into the high-pressure channel 5, it enters the annular cavity 17 and from there through the valve 6 to the fuel-injection nozzle. In this case, the valve 3 is under the action of the spring 9 on its saddle 4, due to which the channel 5 is disconnected from the branch channel 7, because the firing pin 10 is not in contact with the valve 3 under the influence of the electromagnet 11 under current, the second connecting channel 12 is also blocked the second valve 13. When the electromagnet 11 is de-energized and the electromagnet 23 is turned on, the firing pin 10 under the action of its spring moves towards the valve 3 and impacts it on the butt end of the sedout 4. High pressure of the fuel from the channel 5 to the bypass valve anal 7 and stopping the filing of a blow to the nozzle through the nozzle. After turning on the electromagnet 11, the valve 3 sits on its

    ce / vTo D, however, the channel 5 remains connected to the channel 8 through the transverse windows, 16 and 19 of the valve 3 and the second connecting channel 12, therefore, the supply of fuel to the nozzle does not start when the pump is under pressure. The beginning of the fuel supply to the injector is determined by the moment of switching off the electromagnet 23, after which the valve 13, moving under the action of its spring 14, stops the transfer of fuel from the channel 5 to the exhaust channel 7.
    Thus, the predicted technical solution provides an increase in the accuracy of regulation of the beginning and end of the fuel supply.
