Известны системы подачи топлива в двигатель внутреннего сгорани , содержащие форсунки, соединенные трубопроводом с топливным насосом, снабженным втулкой с отсечным отверстием и размещенным в ней плунжером с отсечной кромкой, последовательно за которой расположена перемычка.The known system of fuel supply to the internal combustion engine, containing nozzles connected by a pipeline to the fuel pump, equipped with a sleeve with a shut-off opening and placed in it a plunger with a cut-off edge, behind which there is a jumper.
Дл повыщени и регулировани остаточного давлени в трубопроводе в зависимости от изменени нагрузки в предлагаемой системе перемычка плунжера имеет криволинейную кромку.To increase and regulate the residual pressure in the pipeline, depending on the load change in the proposed system, the jumper plug has a curvilinear edge.
На чертеже дана схема описываемой системы .The drawing is a diagram of the described system.
Система содержит форсунки 1 с клапанами, соединенные трубопроводом 2 с топливным насосом 3, снабженным герметичным нагнетательным клапаном (на чертеже не показан) и втулкой 4 с отсечными отверсти ми а и размещенным в ней плунжером 5 с отсечной кромкой 6, последовательно за которой расположена перемычка 7 с криволинейной кромкой 8.The system contains nozzles 1 with valves, connected by pipeline 2 with a fuel pump 3, equipped with a pressure-tight valve (not shown) and sleeve 4 with cut-off holes a and plunger 5 placed in it with cut-off edge 6, sequentially behind which is a jumper 7 with curved edge 8.
При движении плунжер 5 после перекрыти его верхней кромкой отсечного отверсти а подает топливо из надплунжерного пространства через клапаны, трубопровод 2 и форсунку 1 в цилиндр двигател .When moving, the plunger 5 after blocking it with the upper edge of the shut-off opening and supplies fuel from the above-plunger space through the valves, pipe 2 and nozzle 1 to the engine cylinder.
После подхода отсечной кромки 6 к отверстию а втулки 4 подача топлива прекращаетс . При дальнейщем движении плунжера 5 после перекрыти криволинейной кромкой 8After the cut-off edge 6 approaches the opening a of the sleeve 4, the fuel supply is stopped. With further movement of the plunger 5 after overlapping curved edge 8
перемычки 7 отсечного отверсти а начинаетс подпитка топливом через клапан насоса трубопровода . Величину перемычки выбирают такой , чтобы давление в трубопроводе в конце подпитки не превышало давлени открыти jumper 7 of the shut-off opening a begins fueling through the valve of the pipeline pump. The size of the jumper is chosen such that the pressure in the pipeline at the end of the feed does not exceed the opening pressure.

When the plunger 5 is rotated, the curvilinear edge 8 of the jumper changes its active stroke and allows the residual pressure in the pipeline to be adjusted according to a given law.
