Abstract: An application system component is provided in the form of a changeable application member such as a nozzle or a bell cup. The application system component includes a transponder for storing component data, from which the component data is readable, and a wear detection device for monitoring of the application system component. The wear detection device includes a wear mark and an optical detector.

Abstract: An interchangeable nozzle is provided), in particular a quick-change nozzle for applying an application agent onto a component and for fastening to a nozzle change system. The nozzle includes a nozzle body having an alignment feature for the angularly correct, mechanical alignment of the nozzle on the change system. The present disclosure also relates to an associated change system and to an associated application system.

Abstract: A pig traversable through a conduit to deliver a liquid, such as a coating material, having a resilient flexible, generally frustoconical sealing lip which is resiliently biased against an internal surface of the conduit and a resilient biasing member engaging and biased against an under surface of the sealing lip, biasing the sealing lip against an internal surface of the conduit. The disclosed embodiments of the resilient biasing member include annular coil springs and serpentine annular metal springs which may be U-shaped in cross-section, including a first leg received against the under surface of the sealing lip and a second leg received against the pig body portion.

Abstract: The invention concerns a pig scraper for cleaning the inside wall of a coating agent conduit. The pig scraper includes a body insertable in the conduit and at least one sealing lip that seals against the inside wall of the conduit and extends parallel to a longitudinal axis of the body. A space is defined between the sealing lip and the body to form a pocket for enhancing the sealing of the sealing lip with respect to the conduit. The length of the sealing lip substantially prevents the lip from folding over on itself in response to a change in the direction of movement of the pig scraper in the conduit.
