ATOMIZER OF VALVE INJECTOR FOR INTERNAL COMBUSTION ENGINE AND METHOD OF ITS ASSEMBLY Russian patent published in 2018 - IPC F02M61/08 F02M61/18 F02M51/06 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in internal combustion engines (ICE) fuel injection systems. Atomizer of valve jet of internal combustion engine, consisting of cylindrical body 1 of atomizer with channels 2 of fuel supply is proposed. Body has through central cylindrical hole 3, end of which is made in form of seating 4. In hole 3 of body 1 of atomizer with the possibility of axial movement rod 5 of valve, one end of which is made in form of valve 6 and the other end is rigidly connected to valve-stem guide 7, spring load with respect to the body of atomizer by means of valve spring 8. Surfaces of the valve 6 and seating 4 of valve are formed as rotation bodies about axis of valve assembly, and their generators are curves of variable radius, angle between tangents to which and axis of valve assembly varies in any range from 0° up to 90°. Method for assembling the atomizer of valve injector is also provided.

EFFECT: improving quality of spraying and accuracy of dosing of injected fuel.
