NOZZLE Russian patent published in 2012 - IPC F23D11/10 F23D11/36 

FIELD: power engineering.

SUBSTANCE: nozzle comprises a body with connection pipes to supply fuel and sprayer, an orifice, a washer with holes, a spraying attachment. At the same time the orifice for fuel supply is arranged in the form of a tilted sleeve with side holes arranged near the connection pipe, the angle of inclination of which towards the vertical line equals to 30°, and in the sleeve cavity to self-control a throughput section of holes there is a plunger installed with a central calibrated spring, the washer with holes is installed between the external surface of the orifice and the inner surface of the body, forming a cavity for the sprayer, and includes holes with an angle of inclination of 30° to the horizontal line, which are arranged in pairs with orifice holes, from the opposite side of the orifice there is a spraying attachment mounted as capable of displacement along the axis and being fixed with a stop nut with a peripheral calibrated spring, forming a slot circular hole with the body, according to the stated invention, side holes for fuel supply are made with an incline to the tangent of the inner circumference of the connection pipe for fuel supply, and holes for sprayer supply shall be made with diametre narrowing along with the sprayer's movement and with an inclination towards the axis of the connection pipe for fuel supply in the same direction as the side holes for fuel supply.

EFFECT: higher intensity of fuel drops mixing with sprayer due to increased area of fuel jets and sprayer contact as a result of swirled fuel and sprayer flows and higher speed of sprayer and fuel travelling in supply channels.
