Abstract

Improvements in the burner devices for liquid fuels characterized in that they consist of a combination of a carrier body of all the organs of the burner; a sleeve located inside this body supported on it in a defined position; an exit orifice of the liquid fuel at the front end of said sleeve; an outlet nozzle located in the front part of the body and supporting the anterior part of said sleeve with which it cooperates; an exit orifice of the air-fuel mixture in the center of said nozzle with the hole in the front part of the sleeve and the orifice of the outlet nozzle aligned; a needle valve located inside the sleeve with the possibility of longitudinal displacement thereof in order to open to a greater or lesser extent or close the exit orifice of said sleeve; a conduit for liquid fuel that empties into the inner part of the sleeve through the body, circulating said fuel in the concentric space that remains between the valve needle and the inner wall of the sleeve; a pressurized air supply duct that opens into the body next to the outer wall of the sleeve by circulating said pressurized air through the concentric space that remains between the outer wall of the sleeve and the inner wall of the carrying body; a plurality of helical course grooves in the front part of the sleeve where it cooperates with the outlet nozzle whose slots are necessarily to be traversed by the air when leaving the nozzle so that this arrangement of helical course slots will be traversed by the the flow of compressed air causes a turbulent movement in it, which drags liquid fuel out of the central hole of the sleeve into it.
