Abstract

Die Erfindung betrifft eine Druckkammerrakel zum Auftragen eines flüssigen Mediums auf eine rotierende Walze (1), welche Druckkammerrakel einen sich axial erstreckenden Rakelkopf (12) aufweist, der mit jeweils einer sich axial erstreckenden und an der Mantelfläche der Walze anliegenden Dosierrakel (13) und Dichtrakel (14) in Umfangsrichtung eine Kammer begrenzt, in der ein sich axial erstreckender Verdrängungskörper (15) unter Bildung eines Druckraums (16) und eines Ablaufraums (17) und unter Belassung eines Auftragsspaltes (18) zur Mantelfläche der Walze (11) angeordnet ist, der von dem flüssigen Medium zur Benetzung der Mantelfläche durchströmt wird, wobei das Medium durch eine Zuführung in den Druckraum (16) geführt wird. Gemäß der Erfindung wird vorgeschlagen, daß Verdrängungskörper (15) und Rakelkopf (12) jeweils einander zugekehrte Kontaktflächen aufweisen, die druckraumseitig zwischen sich wenigstens einen Spalt begrenzen, der in den Druckraum (16) mündet und diesen mit der Zuführung verbindet, so daß das Medium in den Druckraum (16) gelangt. Mit einer solchen Anordnung ist es möglich, den Spalt beliebig eng zu gestalten.
