ABSTRACT:
To prevent dripping of liquid from an outlet opening of a line, a drip suon device is assigned to the end of the line; the drip suction device has a housing which surrounds the end of the line with the formation of a chamber connected to the interior of the line via through openings and negative pressure can be applied to it via another line to suck up liquid residues which remain in the area of outlet opening after the liquid flow through the line is shut off, and a circuit to activate the drip suction device to apply negative pressure to the chamber when the liquid flow through the line is interrupted by a shutoff element assigned to the line.
