MIXING DEVICE Russian patent published in 1999 - IPC

FIELD: atomization of liquid in gas jet. SUBSTANCE: gas duct located directly around the nozzle has a reduced cross-section area of flow near the nozzle forming a section in the form of a Venturi tube. The duct surrounds the nozzle and is aligned with the nozzle located in the center of the duct. The nozzle has a peripheral duct which changes into the gas duct, runs in circumference around the nozzle and is formed by the opposite surfaces passing radially from 5 to 175 deg. relative to the duct axis, or from 20 to 160 deg. , or from 30 to 150 deg. The section in the form of a Venturi tube extends upwards along the nozzle. The opposite surfaces, forming the duct, are formed by the respective engageable parts of the nozzle valve selectively moving relative to one another. One of the valve components, forming the nozzles duct, is connected to the rod of the nozzle valve located along the duct axis and selectively moving with a slip to shift one part of the valve relative to the other. The gas valve facility is installed above the nozzle and made for selective movement between the open and closed positions. The movable components of the nozzle valve and the gas valve facility are made for a shift to the closed position and transfer from the closed position by a mechanical and/or electric actuator, which may be made in the form of a solenoid or mechanical selector switch. The nozzle valve rod is made for telescopic insertion and direction in the gas valve rod and has an increased part influenced by the end stop in the gas valve rod. EFFECT: increased gas speed and improved fuel atomization, which is especially useful in internal combustion engines, through it is applicable in any other context requiring atomization of liquid in a gas jet. 13 cl, 16 dwg
