The invention concerns a rotary nozzle combination (P) for coating product comprising an atomizing bowl (3) and a rotor (11) adapted to rotate the bowl about a geometrical axis (X-X′), and means (4, 5, 6, 7) for controlling the presence and/or proper mounting of the bowl (3) on the rotor (11). The rotor (11) is spaced apart from a non-rotating part (P1) and the control means comprise first means (4, 5) enabling a force (F3) to be applied on the bowl (3) tending to vary the thickness of an air-film of the pneumatic thrust bearing (P1), as well as second means (7, 8) for determining the air pressure in the bearing (P1). The pressure of air in the thrust bearing (P1) can be determined when the latter is normally supplied and compared with at least one reference value.
A rotary sprayer for spraying coating material, the sprayer comprising an atomizer bowl and a member suitable for driving said bowl in rotation about an axis, said member being held at a distance from a non-rotary portion of the sprayer by means of at least one air thrust bearing, the sprayer being characterized in that it includes means for monitoring the presence and/or proper mounting of said bowl on said drive member, said means comprising:
A method of verifying the operating state of a rotary sprayer for spraying coating material, the sprayer including an atomizer bowl and a member for driving said bowl in rotation about an axis, said member being subjected to a force that is axial at least in part and being held spaced apart from a non-rotary portion of the sprayer against said force by means of an air thrust bearing, said method comprising a step consisting in:
