  • Publication number: 20250020260
    Abstract: The disclosure relates to a coating agent supply device for supplying coating agent (e.g. paint) to an applicator (e.g. rotary atomizer). The coating agent supply device according to the disclosure has a pig source station, a pig destination station and a pig line which connects the pig source station to the pig destination station. The pig line contains a pig package with two pigs for clamping the coating agent between the two pigs of the pig package for coating agent transport between the pig source station and the pig destination station. Furthermore, the coating agent supply device has a lubricant supply line for supplying a lubricant for friction-reducing lubrication of the pigs in the pig line when moving the pig package between the pig destination station and the pig source station.

  • Patent number: 11623232
    Abstract: The disclosure relates to an applicator (RZ), in particular a rotary atomizer, for the application of a coating agent, in particular a two-component paint, comprising a first coating agent connection (SL) for feeding a first coating agent, in particular a basic resin of a two-component paint, a first coating agent strand (L1-L4), which extends in the applicator (RZ) from the first coating agent connection (SL) and carries the first coating agent, and a first valve (SLV1), which is arranged in the first coating agent strand (L1-L4) and controls the flow of the first coating agent, wherein the first valve (SLV1) can be controlled by a first control signal. It is proposed that a first pressure-relief valve (SLV1), which is actuated by its own medium, is arranged in the first coating agent strand (L1-L4) and, to avoid a problem being caused by excessive pressure, opens automatically when the pressure upstream of the first pressure-relief valve (SLV1) exceeds a certain maximum pressure.
