Various exemplary illustrations of a coating agent device are disclosed. In one example, a coating agent device may be a coating agent valve, e.g., for influencing the discharge of a coating agent. The coating agent device may include a plug-in or pluggable fastening base configured to facilitate a plug-in or pluggable mounting of the coating agent device. In some examples, the coating agent device may prevent relative rotation of the device relative to a mating component.

Coating agent device and coating device

A coating system applicator component, e.g. a valve or bell cup, which may be used to be wetted and/or flown through at least in some sections by a coating agent, is provided. The applicator component includes a cylindrical holding part configured to releasably couple a mount of the coating system, as well as an applicator thread on the holding part. The applicator thread includes first and second applicator flank surfaces each obliquely oriented to a radial direction of the holding part, the first and second applicator flank surfaces being asymmetric about the radial direction of the holding part. The first and second applicator flank surfaces are configured to be parallel to and interface with first and second mount flank surfaces of a thread of the mount, respectively, upon a coaxial, threaded engagement between the holding part and the mount.

Coating system component comprising at least one holding part

A coating system component which may be used to be wetted and/or flown through at least in some sections by a coating agent. The component may include a fastening base and at least one holding part which is arranged on the fastening base for being fastened to or in a coating system device. The holding part may be an external thread having a special configuration in order to meet the special requirements of painting facilities, according to various exemplary illustrations. Furthermore, a corresponding coating system device may be provided, to which the coating system component can be fastened in a detachable manner.

Rotary atomizer component

The disclosed apparatus includes a supply line () between a source of liquid paint () and an applicator () having at least two pigs (A andB) and a source of liquid solvent () which delivers solvent () between the two pigs (A andB) and the pigs (A andB) are driven by paint () from adjacent the paint source () to the applicator (). The apparatus further includes a second source of liquid solvent () which delivers solvent () between the pigs (A andB) adjacent the applicator () and the pigs (A andB) are returned through the supply line (), thereby flushing the supply line (). In the disclosed embodiment, the source of liquid paint () is a piston dosing device () which receives paint () from a color changer or the like and delivers a predetermined volume of paint () to the applicator (). The delivery line () preferably includes a friction resistant inner layer, an intermediate dielectric layer and a protective outer layer.

Method and apparatus for delivering paint to an applicator and flushing same

A paint delivery and application system including a color changer, at least two paint canisters and a paint applicator, a first pair of supply lines connected between the color changer and the paint canisters and a second pair of supply lines connecting the paint canisters and the paint applicator, wherein the paint canisters operate in tandem permitting delivery of a first paint to one of the paint canisters while a second paint canister is electrically isolated from the color changer and is delivering paint to the applicator. In one disclosed embodiment, the delivery line from the paint canisters to the applicator includes two pigs and solvent is delivered between the pigs, such that this system is self purging.

Paint delivery and application system and method

To supply a powder lacquer sprayer, the coating powder is pressed by a pig through the supply line and, in the process, it is fluidized from the side of the pig which is turned toward the powder. The fluidization air can be led to the powder, for example, by a central passage opening of the pig or through an air permeable wall of the connection line. For the dosage of the coating powder, one uses the push medium which drives the pig.
