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.

Abstract: The two sealing lips of a pig, which is driven by a pushing medium for delivering a coating material for the mass-production coating of workpieces, have a self-sharpening sealing edge contacting the inner wall of the piggable line. Flat outer surface parts of the sealing lip formed ahead of and behind the sealing edge are angled against the inner wall of the line for an unloaded pig, while the inner surface part in the axial direction is pressed flat against the line under loading by the pushing medium. The production of the pig is realized through turning and subsequent shaping of the sealing lips in a transport sleeve in which the pig is kept and brought to its insertion location.

Abstract: A heat exchanger body for a vehicle heater has an elongated circumferential wall (26), which defines a flow space (40) for combustion products together with an inner side (38). The circumferential wall (26) is essentially not provided with heat transfer ribs on its inner side (38) in a first length section (50) of the flow space (40), which said first length section leads away from an inlet opening (44). The circumferential wall (26) is provided with heat transfer ribs (56) on its inner side (38) in a second length section (52) leading to an outlet area (48).
