Abstract: An air/oil mist generator (1, 1A), comprising an accumulation chamber (2) inside which a mist of oil particles in air accumulates, the accumulation chamber (2) being provided with at least one first mist outlet (4), at least one nebulizer (3, 3A) feeding into the said accumulation chamber (2), wherein the accumulation chamber (2) is associated with a differential pressure regulator (12), which feeds the compressed air into the accumulation chamber when the difference between the internal pressure of the accumulation chamber (2) and the nebulizer supply pressure (3) exceeds a predefined threshold value.

Abstract: An air/oil mist generator (1A) including an accumulation chamber (2) inside which a mist of oil particles in air accumulates, the accumulation chamber (2) being provided with at least a first mist outlet (4), the generator (1A) comprising a nebulizer (3, 3A) feeding into the said accumulation chamber (2), the nebulizer (3) being optimised to operate at a first pressure level and being fed by a first line (BA) of compressed air at the said first pressure level, the generator (1A) further including a further nebulizer (3A) which also feeds into the accumulation chamber (2) optimised to operate at a second pressure level which is higher than the first pressure level, the further nebulizer being fed by a second line (AL) of compressed air at the second pressure level; the first line (BA) being optionally associated with a non-return valve (807) which prevents a backflow coming from the accumulation chamber (2).

Abstract: A generator of air/oil mist includes an accumulation chamber for a mist of particles of oil in air, and equipped with a first mist outlet and a nebulizer feeding into the accumulation chamber, the nebulizer including a first nozzle supplied with pressurised air, which features at least a first channel supplied with the pressurised air, each channel being equipped with an outlet on a surface of the first nozzle partially defining a first chamber axially symmetrical with respect to an axis, the channels being positioned to generate a rotation of the air fed into the first chamber around the said axis, the surface of the first nozzle featuring a section converging towards an outlet hole, the nebulizer featuring a second nozzle supplied with oil and feeding out into the first chamber so that the oil is suctioned via the second nozzle because of the air flowing through the first chamber.

Abstract: A minimal lubrication device including a lubricating fluid storing tank, conduit for supplying the lubricant pressurized to at least one modular element. The at least one modular element including a lubricating fluid conduit intercepted by flow regulator and compressed air conduit, such conduits fluidically connected to air and lubricant mixing element. The flow regulator including a shutter that can be at least partially housed in calibrated hole and movable between upper and lower stroke position ends. The calibrated hole in fluid communication, on one side, with pressurized lubricant delivery and, on the other side, with the mixing element. The shutter having at least one conical profile portion insertable in the calibrated hole. The conical profile portion has a surface groove facing a surface defining the calibrated hole at least when the shutter is in an intermediate position between the lower and upper stroke position ends.

Abstract: A progressive modular distributor device for the division between a plurality of outlets of a lubricant fluid, said distributor including a first and a second base between which are sandwiched at least three distributor modules. The bases being interconnected by tie rods which pass through openings in the modules. A first surface of at least one of the modules presents at least one projecting part integral with the module. A second surface of a second of the modules, resting on the first, presents a corresponding housing in which the projecting part is inserted. The projecting part and the housing shaped to prevent reciprocal movement of the first and second module at least along an axis perpendicular to an axis of the tie rods when the projecting part is inserted in the housing.
