Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
96 words
A vortex-type oil mist generator comprising an oil storage chamber, a vortex chamber adapted to create a rotating flow of gas and having tangentially arranged inlet openings for admitting a pressurized gas and an axial outlet opening, the ratio of the total area of said tangentially arranged inlet openings to the area of said axial outlet opening not exceeding 0.7, thus providing a suction area within said vortex chamber, and means defining an oil delivery duct having an inlet portion in communication with said oil storage chamber and an outlet portion extending into said suction area.
Claim 2
Dependent Claim
96 words
A vortex-type oil mist generator comprising an oil storage chamber, a vortex chamber adapted to create a rotating flow of gas and having tangentially arranged inlet openings for admitting a pressurized gas and an axial outlet opening, the ratio of the total area of said tangentially arranged inlet openings to the area of said axial outlet opening not exceeding 0.7, thus providing a suction area within said vortex chamber, and means defining an oil delivery duct having an inlet portion in communication with said oil storage chamber and an outlet portion extending into said suction area.
Claim 3
Dependent Claim
36 words
A generator as defined in claim 1, wherein the ratio of the total area of said tangentially arranged inlet openings to the area of said axial outlet opening is in the range from 0.3 to 0.5.
Claim 4
Dependent Claim
41 words
A generator as defined in claim 1, wherein said outlet portion of said oil delivery duct is arranged within said vortex chamber and is adjustable toward and away from said axial outlet opening to reduce and to increase, respectively, the suction.
Claim 5
Dependent Claim
41 words
A generator as defined in claim 1, wherein said duct accommodates a core arranged within said outlet portion thereof and having passageways to deliver the oil into the peripheral zone of the suction area and being in communication with said duct.
Claim 6
Dependent Claim
22 words
A generator as defined in claim 4, wherein said passageways of said core are disposed eccentrically to the axis of said core.
Claim 7
Dependent Claim
36 words
A generator as defined in claim 4, wherein said passageways of said core are spiral grooves, the axial direction of the generatrices of said grooves coinciding with the axial direction of the rotating flow of gas.
Claim 8
Dependent Claim
63 words
A generator as defined in claim 4, wherein said core is rotatable with respect to said outlet portion of said duct and is provided with an impeller arranged coaxially with said core and rigidly secured thereto, and said passageways are spiral grooves, the axial direction of the generatrices of said grooves being opposite to the axial direction of the rotating flow of gas.
