The present invention relates to a coating product atomizer comprising a main body, an air supply skirt attached to the main body and magnetic attraction means between the magnetic body and the air supply skirt. The atomizer comprises a magneto-pneumatic or magneto-hydraulic system which includes a magnetic device for hooking the air supply skirt to the main body and a pneumatic or hydraulic mechanism for locking and clamping the air supply skirt to the main body.

The present invention relates to a rotary atomizer for coating products comprising a main body and a bowl rotated by a rotating member about a axis of rotation defined by the main body. The bowl is equipped with first means of magnetic coupling apt to cooperate with matching second means of magnetic coupling fastened to a non-rotating part of the atomizer. The first and second means of coupling are apt to exert a force at least partially axial with respect to the axis of rotation of the bowl, the force inducing the coupling in rotation of the bowl with the rotating member. The second means of magnetic coupling are supported by an air supply skirt directly mounted on the main body.

A spraying member for a coating product rotary projector which carries at least one mechanical locking weight on a drive shaft of the rotary projector. The weight is movable, radially to the central axis of the bowl and according to a centrifugal direction relative to this axis, between an unlocked position, in which it does not oppose the mounting of the spraying member on the drive shaft or its dismantling relative to this shaft, and a locked position, in which it opposes the dismantling of the bowl relative to the drive shaft.

A turbine rotor, e.g., for a drive turbine of a rotary atomizer, is disclosed having a rotatably supported turbine shaft with the potential for mounting an atomizer wheel, and having at least one drive turbine wheel having a plurality of turbine blades. The turbine blades of the drive turbine wheel may be impinged on during operation by a drive fluid in order to drive the turbine rotor. The drive turbine wheel may be designed for the drive fluid to axially impinge on the turbine blades. A complete drive turbine having such a turbine rotor is also disclosed, as well as a complete rotary atomizer and individual exemplary components of the drive turbine.

A rotary atomiser spindle arrangement includes a rotary atomiser spindle having a shaft and a bell cup releasably mounted on the shaft. The shaft and mounting portion of the bell cup include respective complimentary taper portions which form an interference fit with each other when the bell cup is mounted on the shaft so locating in the bell cup in relation to the shaft, wherein the rotary atomiser spindle arrangement including a bell cup retention arrangement having retention biasing for urging the complimentary taper portions against one another when the bell cup and shaft are at a first relative rotational position with respect to one another whilst the bell cup retention arrangement allows at least demounting at a second relative rotational position. The bell cup retention arrangement includes latching mechanism for latching the bell cup and shaft in the first relative rotational position.

The disclosure relates to a bell plate for a rotary atomizer for applying a coating agent (e.g. paint) to a component (e.g. motor vehicle body component). The bell plate according to the disclosure comprises a metallic base body and a transponder which can be read out wirelessly and is integrated in the bell plate. The disclosure provides that the transponder is arranged on the front side in the base body or is embedded in the outer outer circumferential surface of the bell plate, which facilitates the read-out of the transponder. Furthermore, the disclosure comprises a suitably adapted atomizer cleaning device having an antenna for reading out the transponder in the bell plate. Finally, the disclosure also comprises a correspondingly adapted operating method.
