Abstract
To supply a powder lacquer sprayer, the coating powder is pressed by a pig through the supply line and, in the process, it is fluidized from the side of the pig which is turned toward the powder. The fluidization air can be led to the powder, for example, by a central passage opening of the pig or through an air permeable wall of the connection line. For the dosage of the coating powder, one uses the push medium which drives the pig.
