Abstract: An oil mist generator of the vortex type comprises an oil storage chamber, a vortex chamber adapted to create a rotating flow of gas, and a duct having an inlet being in communication with the oil storage chamber and an outlet delivering the oil into the rotating flow of gas. The vortex chamber is provided with tangentially arranged inlet openings delivering a pressurized gas thereinto and an axial outlet opening, the ratio of the total area of the tangentially arranged inlet openings to the area of the axial outlet opening not exceeding 0.7, thus providing a suction area within the vortex chamber. The duct outlet is disposed within the vortex chamber suction area.

Abstract: A vortex-type oil mist generator comprises two nozzles, each having tangential gas delivery channels to create a rotating flow of gas, an oil delivery duct supplying the oil into the rotating flow of gas, whereby a rotating flow of mist is created, and an oil mist outlet. In said generator, the nozzles are mutually arranged so that their oil mist outlets face each other, while the tangential gas delivery channels of the nozzles are arranged so as to ensure the rotation of the oil mist flow exiting from the outlet of the first nozzle in the direction opposite to the direction of rotation of the oil mist flow exiting from the outlet of the second nozzle.Such a mutual arrangement of the nozzles as well as their design makes it possible to generate a high density mist having an increased degree of dispersity.
