Description

Изобретение относитс  к устройствам дл  подачи и распыливани  топлива в бескомпрессорных двигател х внутреннего горени  с применением топливного насоса с поворотным косо зафрезерованным сбоку плунжером и автоматически действующей форсунки с диференциальной иглой.The invention relates to devices for feeding and spraying fuel in non-compressor internal combustion engines using a fuel pump with a rotatable obliquely milled plunger from the side and an automatically operating nozzle with a differential needle.

G целью точной и резкой подачи топлива, а также и резкого заканчивани  ее, одинакового распылени  топлива при малом расходе в предлагаемом устройстве пространство под иглою форсунки соединено обходными наклонными каналами с пространством под аккумул торным плунжером, который помещают над форсуночной иглой и по одной оси с нею.The purpose of accurate and sharp fuel delivery, as well as its abrupt completion, uniform fuel spraying at low consumption in the proposed device, the space under the needle of the nozzle is connected bypassing inclined channels with the space under the battery plunger, which is placed above the nozzle needle and along the axis .

На схематическом чертеже фиг. 1 изображает вид устройства дл  подачи и распыливани  топлива в бескомпрессорных двигател х внутреннего горени ; фиг. 2 - вид сбоку плунжера насоса.In the schematic drawing of FIG. 1 shows a view of a device for feeding and spraying fuel in non-compressor engines for internal combustion; FIG. 2 is a side view of a pump plunger.

Устройство состоит из автоматически действующей форсунки закрытого типа специальной конструкции и плунжерного топливного насоса; Форсунка имеет обыкновенную диференциальную иглу /2, котора  прижимаетс  к седлу, сопла пружиной 25. На одной оси с пружиной и иглой расположен аккумул торный плунжер 3, нагруженный пружиной 2 и двигающийс  в пробке 4, ввертыва (497)The device consists of an automatically operating nozzle of a closed type with a special design and a plunger fuel pump; The nozzle has an ordinary differential needle / 2, which is pressed against the seat, a nozzle by a spring 25. On one axis with a spring and a needle is an accumulator plunger 3 loaded with spring 2 and moving in plug 4, screwed in (497)

емой в корпус 24 форсунки. Пространства под иглой /2 и под плунжером 3 сообщаютс  между собой обходными наклонными каналами 5 и /7, которые, в свою очередь, сообщаютс  с топливоподающей трубкой /5, через канал 7 и шариковый клапан 9, открывающийс  только при движении топлива в форсунку . Канал 7 сообщаетс  с полостью 26 пружины иглгл 72 через канал 8, кольцевую выточку 0 и сверление 27, указанное пунктиром. К форсунке топливо подаетс  плунжерным насосом, имеющим плунжер 77 с косой кромкой J8 и канавкой 22. Топливо всасываетс  плунжером 77 через отверстие 23 при ходе плунжера 77 вниз. При ходе плунжера вверх топливо начинает нагнетатьс  тогда, когда коса  кромка /8 плунжера 77 закроет окно 23. Поворачиванием плунжера руко ткой 20 через втулку 27 регулируетс  количество подаваемого топлива. Вследствие того, что перепуск топлива производитс  в начале подачи, начало подачи насоса дл  посто нного опережени  и при изменении количества впрыскивани  топлива непосто нно, а посто нным  вл етс  конец подачи насоса, наступа ющий тогда, когда окно 23 открываетс  в канал 22, идущий вокруг плунжера, и давление в насосе и топливопроводе резко падает. От насоса топливо подаетс  через трубку J3 к форсунке и через24 nozzle into the housing. The spaces under the needle / 2 and under the plunger 3 communicate with each other by the bypass inclined channels 5 and / 7, which in turn communicate with the fuel supply tube / 5, through the channel 7 and the ball valve 9, which opens only when the fuel flows into the nozzle. The channel 7 communicates with the spring cavity 26 of the needles 72 through the channel 8, the annular recess 0 and the drilling 27 indicated by the dotted line. The fuel is supplied to the injector by a plunger pump having a plunger 77 with a slanting edge J8 and a groove 22. The fuel is sucked by the plunger 77 through the opening 23 as the plunger 77 moves down. As the plunger moves upward, the fuel starts to inject when the spit edge / 8 of the plunger 77 closes the window 23. The amount of fuel supplied is adjusted by turning the plunger with the handle 20 through the sleeve 27. Due to the fact that the fuel is bypassed at the beginning of the supply, the beginning of the supply of the pump for a constant advance and when the amount of fuel injection varies the plunger, and the pressure in the pump and the fuel line drops sharply. From the pump, fuel is supplied through tube J3 to the nozzle and through
