DEVICE FOR GENERATION OF GAS-DROP JET Russian patent published in 2011 - IPC B05B7/10 

FIELD: machine building.

SUBSTANCE: in device for generation of gas-drop jet liquid is supplied in two directions, including axial supply of liquid through supplying branch and through confusor and cylinder nozzle successively connected to it. Liquid is tangentially supplied through a case in form of a cylinder-conic sleeve coaxial to the cylinder nozzle. A vortex circular chamber with a branch for supply of liquid is secured on a cylinder section of the sleeve. Two rows of liquid supplying tangential channels are made on ends of the circular chamber. At least three tangential channels connecting the circular chamber with the cylinder cavity of the case are made in each row. A profiled nozzle made in form of a perforated shell is coaxially attached to the circular chamber. A shape of the shell is formed with surface of revolution of the second order, for example, hyperboloid, paraboloid or ellipsoid.

EFFECT: raised efficiency of fire extinguishing by increased flight range of gas-drop jet and its fine dispersity at interaction with an object.
