POSSIBLY APPARATUSES FOR REALIZING ACOUSTIC ACTION UPON PROCESS OF FUEL COMBUSTION Russian patent published in 2003 - IPC

SUBSTANCE: acoustic device includes housing with nozzle unit in the form of combined cone with resonator chamber joined with housing by means of threaded joint. In body of nozzle unit there are four nuts with inner spherical surface arranged symmetrically or asymmetrically relative to its lengthwise axis. Inside each nut jet is arranged. Said jet has outer spherical surface passing to outer and inner cylindrical protrusions arranged mutually opposite and inner surface in the form of Laval's nozzle. On nozzle unit springy sleeve with lengthwise grooves for outer cylindrical protrusions is stationary mounted. In resonating chamber sleeve with cross grooves for inner cylindrical protrusions is mounted with use of threaded joint. In bottom of resonating chamber there is threaded recess for placing resonator with possibility of moving it along lengthwise axis of nozzle unit. It is possible to use resonator with working surface having different geometry. EFFECT: possibility for create powerful acoustic action upon process of fuel combustion. 3 dwg
