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. In addition, the coating agent supply device according to the disclosure has a controllable lubricant valve, which connects the lubricant supply line to the pig line in order to feed the lubricant into the pig line at a lubricant feed point. The disclosure provides that the lubricant feed point is located in the pig line between the pig source station and the pig destination station.
