Abstract

Ein Rohrventilator (10) für gasförmige Medien weist ein Diagonallaufrad (40) mit mehreren Schaufeln (54) und eine sich abströmseitig an das Diagonallaufrad (40) anschließende Leiteinrichtung (42) zur Druckerhöhung des Mediums auf. Die Schaufeln (54) des Diagonallaufrades (40) sind an einer Tragscheibe (50) und an einer Deckscheibe (56) befestigt. An das Diagonallaufrad (40) schließt sich in axialer Richtung (22.1) die Leiteinrichtung (42) an.
