摘要： 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.

摘要： 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.
