The disclosure relates to a rinsing apparatus for connection to an application-agent main channel of an application-agent changeover unit and preferably for the continuous inflow of a rinsing agent into a flow of rinsing air, having a main line for transporting rinsing air and having a rinsing-agent line for transporting a rinsing agent. The rinsing apparatus is distinguished in particular in that the rinsing-agent line opens out into the main line by way of a mouth opening in order to generate a preferable y continuous flow of a rinsing-air/rinsing-agent mixture for introduction into the application-agent main channel. The disclosure also relates to a corresponding rinsing method.

Rinsing apparatus for connection to an application-agent main channel of an application-agent changeover unit

The disclosure relates to an applicator (RZ), in particular a rotary atomizer, for the application of a coating agent, in particular a two-component paint, comprising a first coating agent connection (SL) for feeding a first coating agent, in particular a basic resin of a two-component paint, a first coating agent strand (L-L), which extends in the applicator (RZ) from the first coating agent connection (SL) and carries the first coating agent, and a first valve (SLV), which is arranged in the first coating agent strand (L-L) and controls the flow of the first coating agent, wherein the first valve (SLV) can be controlled by a first control signal. It is proposed that a first pressure-relief valve (SLV), which is actuated by its own medium, is arranged in the first coating agent strand (L-L) and, to avoid a problem being caused by excessive pressure, opens automatically when the pressure upstream of the first pressure-relief valve (SLV) exceeds a certain maximum pressure.

Applicator, in particular rotary atomiser

The disclosure relates to a needle valve for controlling a fluid flow of a coating agent (H, SL) in a painting system, particularly for controlling a fluid flow of a two-component mixture consisting of two coating agent components (H, SL), particularly a two-component paint made from a master batch (SL) and a curing agent (H), comprising a valve seat () and a displaceable valve needle () with a needle stem and a valve head (), wherein the valve head () closes the valve seat () in a closed position of the valve needle (), while the valve head () opens the valve seat () in an opened position of the valve needle (). The disclosure provides a flexible membrane () which surrounds the valve needle () annularly and in a sealing manner upstream before the needle head ().

Valve

The disclosure relates to a coating agent valve () for controlling a flow of fluid of a coating agent mixture consisting of two coating agent components (H, SL), in particular a two-component paint consisting of a master batch (SL) and a hardener (H). The coating agent valve according to the disclosure () comprises a valve seat, a displaceable valve head (), a valve drive () for displacing the valve head () and a displaceable valve needle () which connects the valve drive () to the valve head () and moves the valve head () in correspondence with the valve drive (). The disclosure provides for an automatic reduction in pressure in order to avoid excess-pressure damage upstream from the coating agent valve ().

Coating agent valve

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

An atomizer for coating, for example automobile bodies, add-on parts and/or truck cabs is provided. The atomizer may be configured to apply one multi-component coating agent and one single-component coating agent from one application element, or to apply two different multi-component coating agents from one application element.

Atomizer and method for applying one-and multi-component coating agents

A color changer system for a painting robot comprises a color changer. A plurality of color feed lines are included on an inlet side of the color changer. A common color line is included on an outlet side of the color changer, and is configured to forward paint selected by the color changer to an atomizer. A color bar comprises a plurality of docking points supplied by the color feed lines. A color extractor is configured to selectively dock onto one of the docking points of the color bar and, while docked to the color bar, extract paint from an associated color feed line and supply the extracted paint to the common color line.

Painting robot color changer system

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.

Exemplary illustrations directed to a rotary piston pump, e.g., for metering a coating agent in a coating installation, as well as exemplary methods of using the same, are disclosed. An exemplary piston pump may comprise a plurality of pump units, each having one cylinder and one rotary piston which carries out a wobbling or tumbling movement in the cylinder.
