Air/oil mist generator

Air/oil mist generator, comprising an accumulation chamber inside which a mist of oil particles in air accumulates, the accumulation chamber being provided with:

• at least one first mist outlet, and
• at least one nebulizer leading into said accumulation chamber, the nebulizer comprising
• a first nozzle fed by pressurized air, the first nozzle including
• at least one first channel fed by the pressurized air, each first channel being provided with an outlet on a surface of the first nozzle,
• wherein the first nozzle at least partially defines a first one axially symmetrical chamber with respect to an axis,
• wherein each first channel is oriented so as to generate a rotation of the air introduced into the first chamber around said axis,
• wherein the surface of the first nozzle provides at least one section converging towards an outlet hole,
• a second nozzle fed by oil and having a delivery hole positioned into an upstream portion of said first chamber so that the oil is sucked through the second nozzle into the first chamber due to the flow of air flowing through the first chamber, wherein the delivery hole of the second nozzle is coaxial with said axis;
• wherein the outlet hole of the first nozzle opens into a divergent channel with a sidewall angled outward from the outlet hole;
• and
• wherein the divergent channel further includes a wall on a plane including an exit section of the outlet hole, said wall joining a perimeter of the outlet hole to the sidewall, and wherein the perimeter of the outlet hole is spaced from the sidewall a distance that is between 1.5 and 4.5 times a diameter of the outlet hole.
