Description
таемого им топлива. Происходит подача тпредварительной лорщии топли:ва.their fuel. There is a supply of pre-lorschy fuel: va.
Нагнетаемое в обоих описываемых случа х ТОПЛИВО, ,на1П1ра вл етс в один и тот же нагнетательпый «анал 3 гильзы 1 за счет двух, диаметрально противоположно paicnoложенных распределительных пазов 7, работающих поочередно, за счет различного углового шага пазов 7 и -калалов 3 гильзы, так как в момент работы одного из пазов второй паз перекрыт глухой поверхностью гильзы. Разница порций основного н дополнительного топли1ва определ етс велкчи«ой ступеньки между дознрующимн кромкаами 10 :и // дозатора 9, котора равна 0,6-0,7 максимального активного хода плунжера. При этом предварительна подача составл ет 20-30% от основной подачи топлива. При малых подачах, когда основной активный ход плунжера 4 менее величины , насос работает только в 1режиме основной подачи топли1ва.Injected in both described cases FUEL, nap1P1ra is in the same blower channel 3 of the sleeve 1 due to two diametrically oppositely laid distribution distribution grooves 7, working alternately, due to the different angular pitch of the grooves 7 and -halo 3 sleeve, since at the time of operation of one of the grooves, the second groove is blocked by the hollow surface of the sleeve. The difference of the portions of the main and additional fuel is determined by the Velcci of the second step between the test edge 10: and // the dispenser 9, which is equal to 0.6-0.7 of the maximum active stroke of the plunger. In this case, the pre-feed is 20-30% of the main fuel supply. At low feed rates, when the main active stroke of the plunger 4 is less than the value, the pump operates only in the 1st mode of the main fuel supply.
Таким образом, при организации раздельных подач основной дополнительной порщий топлива иовыш аетс интенсивность пода-чи и точность дозировани .Thus, when organizing separate feeds, the main additional spurious fuel increases the flow rate and the metering accuracy.
