Patent number: 8430340Abstract: A rotary atomizer component, such as for a steering air ring or bell cup for a rotary atomizer with at least one steering air jet for delivering steering air (or controlled air) and a rotary bearing shaft where, in axial direction between the bell cup and the steering air jet, a circumferential annular gap is located. A shaft cover in form of a bushing covers the bearing shaft, when mounted, at least partially in the annular gap area between the bell cup and the steering air jet. In addition, the annular gap space between the front surface of the bearing unit and the internal surface facing it axially or any other front element of the atomizer is sealed in a radial way internally against the externally accessible area of the shaft. The sealing element provided for this purpose is located along the internal circumference of the air-steering rings or front element and able to be attached to the front surface of the bearing unit in a way that it is elastically deformable.Type: GrantFiled: November 23, 2009Date of Patent: April 30, 2013Assignee: Dürr Systems Inc.Inventors: Frank Herre, Peter Marquardt, Hans-Jurgen Nolte, Michael Baumann, Bernhard Seiz

Patent number: 8097293Abstract: The invention relates to an operating method for an atomiser (1) for the coating of structural components, particularly of vehicle body parts, with the following steps: Application of a spray jet of a coating agent through the atomiser (1); discharge of a first guide air flow (11) for the formation of a spray jet; determination of at least one application parameter (?, ?, T, BC/CC, Qvarnish, n, U,) which reproduces a property (?, ?, T, BC/CC) of the applied coating agent or an operating variable (Qvarnish, n, U) of the atomiser (1) as well as influencing of the first guide air flow (11) as a factor of the application parameter (?, ?, T, BC/CC, Qvarnish, n, U,). Within the framework of the invention, there is the alternative option that fluctuations of the application parameters and, based thereon, variations of the spray jet width are taken into account by means of an adaptation of the path spacing (d) between the adjacent coating agent paths for the purpose of keeping the path overlapping constant.Type: GrantFiled: September 19, 2007Date of Patent: January 17, 2012Assignee: Durr Systems Inc.Inventors: Benjamin Wöhr, Hans-Jürgen Nolte, Andreas Fischer, Peter Marquardt, Frank Herre, Marcus Frey
