Abstract: A device for generating a jet of two-phase fluid, comprising a nozzle having a main duct that is fed with a pressurized gaseous fluid and opens into a mixing chamber, and at least one secondary duct that is fed by at least one pressurized fluid and opens into the mixing chamber in a direction forming a non-zero angle with the axis of the main duct. The mixing chamber has a convergent-divergent cylindrical wall having a constriction defining an opening in the plane perpendicular to the axis of the main duct. The convergent part of the wall has a frustoconical region in the continuation of the axis of the at least one secondary duct so as to form a fragmentation chamber for the liquid phase.

Abstract: The invention relates to a gun for cleaning by way of air or a sprayed air/liquid mixture, having: a body (2), from which there extends a butt (3) provided with at least one inlet (5) for a pressurized liquid and an inlet (6) for pressurized air, a mechanism (12) for selecting the operating mode of the gun, interposed on the air circuit (9) and liquid circuit (8) thereof, a device (60) for breaking up the liquid into droplets by throwing the liquid flowing in the liquid circuit (8), and a trigger (14) that controls the selection mechanism (12) and is able to take up a first position closing the outlet nozzle (7) and a second position in which only the air exits through the outlet nozzle (7) or a third position in which the air loaded with droplets exits through the outlet nozzle (7).

Abstract: The invention concerns a machine characterized in that it uses the combination of at least one club support (13), at least two wheels (5) arranged on either side of the head (6) of the club to be cleaned, and of its support (13), each bearing at their periphery (8) a brush (10) consisting of bristles (11) the height H of which varies on the periphery from a minimum height A to a maximum height B before decreasing to the initial minimum value A; each of the two brushes being motorized and rotatably mounted on an arm (12) itself oscillating. The geometry of the assembly being adapted so that said two wheels are angularly offset by 180° opposite each of their respective brushes (10), and so that the oscillating movement of the arms (12), combined with the rotation of the wheels (5), and the helical geometry of the bristles (11), is such as to apply said bristles of both brushes on all the shapes, surfaces, angles, projections of the head (6) and to perform an efficient wavelike cleaning operation.

Abstract: A device for transferring pulverulent material, for example, powdery material, including an enclosure (3) wherein the pulverulent material to be transferred is stirred and pressurized; a first pipe (8) and a second pipe (9) which transport the material towards its destination; and a gas intake (14, 15) for introducing gas to the second pipe (9). In one aspect of the invention, pipe (8) forms a nozzle (12), oriented in the direction of the material flow and directed toward second pipe (9). The gas intake (14, 15) may emerge at the lower end of the first pipe (8), outside the nozzle (12), wherein the gas is introduced into the second pipe (9) through a plurality of through orifices (20) oriented substantially parallel to the flow direction of the pulverulent material.
