A liquid dispensing device includes a body, a nozzle on an end of the body, a liquid container coupled to the body, and a piston configured to move in the body so as to control an ejection of liquid from the nozzle. The piston and the nozzle are configured to be detached from the body as an assembly.

A bowl for spraying a coating product, intended to be integrated into a rotary spraying apparatus for spraying a coating product. The spraying apparatus includes a turbine for rotating the bowl about an axis of rotation, and a body that defines the axis of rotation and includes shaping air ejection orifices arranged in a crown. The bowl includes a body which is centered in relation to an axis and which defines an inner radial surface for distributing the coating product to a spraying edge, as well as an outer radial surface. The outer radial surface of the bowl includes a deflector for at least partially directing a flow of cleaning product towards the crown of the body, the cleaning product flowing along the outer radial surface towards the spraying edge.

A system for painting a structure includes a motorized, wheeled vehicle that is movable along a surface and includes a frame and a lift structure coupled with the frame. The system also includes a support structure supported by the lift structure, and a table supported by the support structure. The table is translatable relative to the support structure. The system also includes a mount structure rotatably coupled with the table and a kit of parts that includes a spray head assembly configured for releasable attachment to the mount structure. The system further includes a paint reservoir and a pump, each being supported by one of the vehicle and the support structure.

The invention relates to a rotary atomizer (1) for coating components comprising a bell cup shaft (3) and a spray bell (4) that is regionally insertable into the bell cup shaft (3) and releasably attached to the bell cup shaft (3). The spray bell (4) includes at least one ferromagnetic element (11, 18) or at least one permanent magnetic element (7) and the bell cup shaft (3) includes at least one permanent magnetic element (7) or at least one ferromagnetic element (11, 18), which are arranged in relation to one another such that the ferromagnetic element (11, 18) and the permanent magnetic element (7) exert a magnetic retaining force on one another acting parallel to the axis of rotation of the bell cup shaft (3) in order to releasably retain the spray bell (4) on the bell cup shaft (3). A particularly secure attachment can be achieved by the bell cup shaft (3) having a conical receiving portion (5) facing the spray bell (4) and the spray bell (4) having a conical insertion portion (9) facing the bell cup shaft (3).

The disclosure relates to a rotary atomizer for applying a spray jet of a coating agent (e.g. paint) to a component (e.g. motor vehicle body component). The disclosure provides that the construction dimensions of the rotary atomizer are coordinated in such a way that the air pressure at the outlet opening of the paint nozzle during operation is lower than the air pressure in the nozzle chamber of the bell cup and in the external rinsing channels in order to prevent a backflow of the coating agent from the outlet opening of the paint nozzle backwards in the direction of the nozzle chamber due to the pressure difference.

The disclosure relates to a bell cup for a rotary atomizer for spraying coating agent (e.g. paint), with a spray-off body with a ring-shaped spray edge for spraying the coating agent, a hub part. Assembly of the bell cup on a rotatable hollow shaft of the rotary atomizer, and a fastening arrangement for form-fittingly fastening of the bell cup on the hollow shaft of the rotary atomizer. The disclosure provides that the fastening arrangement in the outer lateral surface of the hub part has a ring-shaped clamping surface that is inclined to the axis of rotation of the bell cup for the contact of a clamping element of the Rotary atomizer in order to clamp the bell cup with an axial clamping force on the hollow shaft of the rotary atomizer.

The bell cup according to the disclosure additionally has an outer rinsing chamber for rinsing the outer circumferential surface of the bell cup with a rinsing agent and an outer rinsing channel for supplying the rinsing agent, the outer rinsing channel being supplied by a rinsing agent supply in the interior of the bell cup and flows into the outer rinsing chamber at its outlet opening.

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.

An annular gap space (18), into which a part of turbine air for driving a turbine (6) and exhaust air discharged from a rear thrust air bearing (12) flow out, is provided between an inner peripheral surface (5B) of a rotational shaft (5) and an outer peripheral surface (17B) of a feed tube (17). Air outflow holes (25) are provided in the rotational shaft (5) to be positioned between a radial air bearing (8) and a rotary atomizing head (16) and to be radially bored through the rotational shaft (5). As a result, the exhaust air flowing in the annular gap space (18) flows out outside of the rotational shaft (5) from the air outflow holes (25) in a position behind the rotary atomizing head (16).
