Abstract

Die Erfindung betrifft eine Flügelzellenmaschine, insbesondere Flügelzellenpumpe, mit einem in einem, mindestens einen Saugbereich und einen Druckbereich ausbildenden Hubring angeordneten Rotor, in dessen Umfangsfläche über die gesamte Breite sich erstreckende, im wesentlichen radial verlaufende Schlitze eingebracht sind, in denen Flügel radial verschieblich gelagert sind und mit seitlichen, feststehenden Begrenzungsflächen (Seitenflächen), die dichtend am Rotor und an den Seitenkanten der Flügel anliegen, wobei mindestens eine der Seitenflächen eine im Bewegungsbereich von Unterflügelkammern verlaufende, zu diesen offene Nut aufweist, und die zweite Seitenfläche im Bewegungsbereich der Unterflügelkammern wenigstens eine dem Saugbereich zugeordnete und mit dem Druckbereich verbundene Unterflügelniere aufweist, so daß entsprechend der Rotorstellung eine Fluidverbindung zwischen der Unterflügelniere und der Nut über die sich gerade im Bereich der Unterflügelniere befindenden Unterflügelkammern besteht, und wenigstens eine dem Druckbereich zugeordnete Unterflügel-Druckniere im Bewegungsbereich der Unterflügelkammern in der die Unterflügelniere aufweisenden zweiten Seitenfläche vorgesehen ist. Es ist vorgesehen, daß die Unterflügelniere (42) sich über einen Drehwinkelbereich (α) erstreckt und die Gesamtfläche der sich im Bereich der Unterflügelniere (42) befindlichen Unterflügelkammern (44) bei einer Rotation des Rotors (18) im wesentlichen konstant bleibt.

The invention relates to a vane machine, in particular a vane pump, with a rotor arranged in a lifting ring that forms at least one suction area and a pressure area, in the circumferential surface of which, essentially radially extending slots extending over the entire width are introduced, in which vanes are mounted in a radially displaceable manner and with lateral, fixed boundary surfaces (side surfaces) which lie sealingly on the rotor and on the side edges of the blades, at least one of the side surfaces having a groove which is open in the movement area of the under-wing chambers, and the second side surface in the movement area of the under-wing chambers has at least one has the lower wing kidney associated with the suction area and connected to the pressure area, so that, depending on the rotor position, a fluid connection between the lower wing kidney and the groove via which is currently located in the area of the lower wing kidney n the lower wing chambers, and at least one lower wing pressure kidney assigned to the pressure area is provided in the movement area of the lower wing chambers in the second side face having the lower wing kidney. It is provided that the lower wing kidney (42) extends over an angle of rotation range (α) and the total area of the lower wing chambers (44) located in the area of the lower wing kidney (42) remains essentially constant when the rotor (18) rotates.
