Изобретение относитс к области ДБИгателестроени .The invention relates to the field of DBT.
Известны топливные насосы дл двигател внутреннего сгорани , содержащие корпус с впускным и нагнетательным каналами, в котором установлены расгфеделительный ротор и кулачкова шайба с внутренними профилированными выступами, контактирующими с роликовыми толкател ми плунжеров, размещен ных в радийльных отверсти х ротора, и устройство дл управлени дозированием впрыскиваемого топлива LlJ.Fuel pumps for an internal combustion engine are known, comprising a housing with inlet and pressure ducts, in which a splitter rotor and a cam washer with internal profiled protrusions are installed in contact with the roller pushers of the plungers located in the radiator openings of the rotor, and a device for controlling the injection of injectors fuel llj.
В этих насосах топливо подвергаетс неоднократному сжатию и расширению (в особенности при малых цикловых подачах), что вызывает его нагрев, а значит и деталей насоса. Это может ухудшить точность дозировани топлива и стабильность впрыске. In these pumps, the fuel is repeatedly compressed and expanded (especially at low cyclic feeds), which causes it to heat up and, therefore, to pump parts. This can degrade the accuracy of fuel metering and injection stability.
Цель изобретени - повышение точности дозировани и улучшение стабильности впрыска.The purpose of the invention is to improve the metering accuracy and improve the stability of the injection.
Поставленна цель достигаетс тем, что в предлагаек ом насосе устройство The goal is achieved by the fact that in the proposed pump the device
дл управлени выполнено в виде двух шайб с внутренними коническими noBepност ми , сопр женными с коническими концами роликов толкателей, и механизма регулировани их взаимного расположени вдоль оси ротора.for control, it is made in the form of two washers with internal conical noBePs, coupled with the conical ends of the pusher rollers, and a mechanism for controlling their relative position along the rotor axis.
Механизм регулировани выполнен в виде подводного привода, св занного с оцной из шайб, профилигюванна торцова поверхность которой контактирует с упорной головкой корпуса.The adjustment mechanism is made in the form of an underwater drive, connected to a shaft of washers, the profiled front surface of which is in contact with the support head of the housing.
Толкатель плунжера снабжен радиальным пазом, в котором установлен фиксирующий элемент, закрепленный наThe plunger pusher is provided with a radial groove in which a fixing element is mounted, fixed to
роторе.the rotor.
ii
Фиксирующий элемент выполнен в виде пластин трапецеидальной формы.The locking element is made in the form of trapezoidal plates.
