Abstract

Изобретение относится к двигателестроению, а именно к топливоподающей аппаратуре двигателей внутреннего сгорания. Задачей изобретения является улучшение качества впрыска топлива и существенное упрощение конструкции форсунки, улучшение долговечности работы форсунки. Поставленная задача решается тем, что топливо подают в виде сплошного полого конуса с углом распыла более 50° через кольцевую щель, образованную конической поверхностью клапана и коническим седлом в корпусе распылителя. Поставленная задача решается тем, что клапан выполнен тарельчатым, обращенным торцом тарелки в цилиндр двигателя, а конической посадочной поверхностью - к седлу корпуса распылителя, распыливающее отверстие выполнено в виде кольцевой щели между седлом корпуса распылителя и конической поверхностью тарелки клапана, возникающей при открытии клапана за счет упругой деформации штока клапана, с противоположной стороны тарелки клапана смонтировано средство для создания предварительного упругого натяга штока. Имеются и другие отличия от прототипа. Преимуществом заявляемого способа и устройства является отсутствие перемещаемых масс материала, а следовательно инерционных сопротивлений, что позволяет работать на скоростных и высоко оборотистых двигателях. Кроме того, этот способ легко поддается автоматизации управления как по количеству, так и по качеству подаваемого топлива. Существенно упрощается конструкция форсунки.The invention relates to engine, namely to the fuel injection equipment of internal combustion engines. The objective of the invention is to improve the quality of fuel injection and a significant simplification of the design of the nozzle, improving the durability of the nozzle. The problem is solved in that the fuel is supplied in the form of a solid hollow cone with a spray angle of more than 50 ° through an annular gap formed by the conical surface of the valve and the conical seat in the spray housing. The task is solved by the fact that the valve is made with a plate, facing end of the plate into the engine cylinder, and a conical seating surface to the spray gun body saddle; elastic deformation of the valve stem, on the opposite side of the valve plate mounted means for creating a preliminary elastic preload of the stem. There are other differences from the prototype. The advantage of the proposed method and device is the absence of movable material masses, and therefore inertial resistance, which allows you to work on high-speed and high-revving engines. In addition, this method is easily amenable to automation of control, both in quantity and in quality of the supplied fuel. Significantly simplified nozzle design.
