Abstract

The invention relates to an engine building, namely to fuel supplying equipment of combustion engines. The aim of the invention is the improvement of fuel injection quality and significant simplification of nozzle construction, improvement of nozzle operation longevity. The set problem is solved by that fuel is fed as continuous hollow cone with a spraying angle of more than 50º through a circular slot formed by valve conic surface and a conic saddle in a body. Theset problem is solved as well by that valve is made as a disc valve, with plate flank addressed to engine cylinder, and conic mounting surface addressed to sprayer body saddle, the spraying hole is made as ring slot between sprayer body saddle and plate conic surface of the valve appearing at valve opening due to elastic deformation of the valve stem, from the opposite side of valve plate the tool for preliminary rod elastic tightness making is installed. There are also other differences from the prototype. The advantage of claimed technique and device is the absence of transferred material masses, and therefore, inertial resistances, that allows to work on high-speed and high-revolution engines. Besides, this technique is easily falling under automated control, according to quantity and quality of fed fuel. The construction of a nozzle is substantially simplified.
