Abstract

Die Erfindung betrifft eine Verdrängerpumpe (10) mit einem Flügel (22) zum gegenseitigen Trennen von zwei Kammern in einem Gehäuseraum, wobei der Flügel (22) von einer im Pumpengehäuse (12) gelagerten Antriebswelle (16) antreibbar und zu dieser in einer zur Antriebswelle parallelen Ebene radial verschiebbar geführt ist und der endseitig an der Innenumfangswand (30) des Gehäuseraumes abdichtend anliegt, indem er in einem Schlitz eines im Gehäuseraum gelagerten und von der Antriebswelle (16) antreibbaren Rotors geführt ist, und wobei der Flügel (22) durch zwei zueinander fluchtende und voneinander unabhängig bewegliche Flügelteilstücke (32,34) aufweist, die teilweise überlappend aneinander anliegen, wobei die Flügelteilstücke (32,34) an ihren einander zugekehrten Seitenflächen (36) nut- und federartig miteinander in Eingriff sind, wobei die Nuten (38) und Federn (40) orthogonal zur Antriebswelle (16) verlaufen.

The invention relates to a positive displacement pump (10) having a vane (22) for mutually separating two chambers in a housing space, wherein the vane (22) can be driven by a drive shaft (16) mounted in the pump housing (12) and to the latter in a drive shaft parallel plane is guided radially displaceable and sealingly abuts the end of the inner peripheral wall (30) of the housing space by being guided in a slot of a housing in the housing and driven by the drive shaft (16) rotatable rotor, and wherein the wing (22) by two having mutually aligned and independently movable wing sections (32,34) which partially overlap each other, wherein the wing sections (32,34) at their mutually facing side surfaces (36) nut and spring-like manner with each other, wherein the grooves (38 ) and springs (40) are orthogonal to the drive shaft (16).
