Publication number: 20230118476Abstract: 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.Type: ApplicationFiled: January 22, 2021Publication date: April 20, 2023Inventors: Rainer Melcher, Thomas Appel, Markus Erhardt, Manfred Michelfelder, Frank Herre

Patent number: 10870117Abstract: 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 (7) and a displaceable valve needle (7) with a needle stem and a valve head (5), wherein the valve head (5) closes the valve seat (7) in a closed position of the valve needle (7), while the valve head (5) opens the valve seat (7) in an opened position of the valve needle (7). The disclosure provides a flexible membrane (18) which surrounds the valve needle (7) annularly and in a sealing manner upstream before the needle head (5).Type: GrantFiled: April 29, 2016Date of Patent: December 22, 2020Assignee: Dürr Systems AGInventors: Frank Herre, Manfred Michelfelder, Michael Baumann, Rainer Melcher, Thomas Buck

Patent number: 10605292Abstract: 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.

Patent number: 10302215Abstract: Exemplary illustrations of a fluid valve, e.g., a return valve for returning residual paint, rinsing agent, and compressed air from a paint line when changing color in a painting system, are disclosed. An exemplary fluid valve may be adjusted between an open position, in which the fluid valve is at least partially open, e.g., for rinsing a paint line with a rinsing agent and for pressurizing the paint line with a new color for the color change, and a closed position, in which the fluid valve is closed, e.g., for applying the new color after the color change. An exemplary fluid valve may switch to the closed position, upon actuation by the medium thereof, e.g., medium flowing through or present in the valve. In another example, a fluid valve may close depending on the fluid present at the input side.Type: GrantFiled: October 4, 2017Date of Patent: May 28, 2019Assignee: Dürr Systems GmbHInventors: Rainer Melcher, Frank Herre, Michael Baumann, Thomas Buck

Patent number: 10047781Abstract: 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.Type: GrantFiled: September 28, 2016Date of Patent: August 14, 2018Assignee: Dürr Systems GmbHInventors: Frank Herre, Joachim Hering, Rainer Melcher, Thomas Buck, Michael Baumann, Bernhard Seiz, Manfred Michelfelder
