Title
(DE) REIBUNGSVAKUUMPUMPE

(FR) POMPE A VIDE A FRICTION
Abstract
(DE)
Die Erfindung betrifft eine Reibungspumpe (1) mit einem feststehenden, Statorschaufelreihen tragenden Bauteil (7) sowie mit einem rotierenden, Rotorschaufelreihen tragenden Bauteil (6), wobei die Stator- und Rotorschaufelreihen konzentrisch zur Drehachse (4) des Rotierenden Bauteils (6) angeordnet sind und ineinandergreifen; um eine in axialer Richtung kurze Reibungspumpe zu schaffen, wird vorgeschlagen, dass sich die die Rotor- und Statorschaufelreihen tragenden Bauteile (6, 7) im wesentlichen radial und die Längsachsen der Schaufeln (2, 3) im wesentlichen axial erstrecken.
(EN)
The invention relates to a friction vacuum pump (1) comprising a fixed element (7) bearing rows of stator blades and a rotating element (6) bearing rows of rotor blades. The rows of stator blades and rotor blades are arranged concentrically with respect to the axis of rotation (4) of the rotating element (6) and engage with each other. In order to create a short friction pump, the elements (6,7) bearing the rows of rotor blades and stator blades extend in a substantially radial manner and the longitudinal axes of the blades (2,3) extend in a substantially axial manner.
(FR)
L'invention concerne une pompe à friction (1) comportant un élément fixe (7) portant des rangées de pales de stator ainsi qu'un élément rotatif (6) portant des rangées de pales de rotor, les rangées de pales de stator et de rotor étant disposées concentriquement par rapport à l'axe de rotation (4) de l'élément rotatif (6) et s'engrenant. L'invention vise à créer une pompe à friction courte dans le sens axial. A cet effet, les éléments (6, 7) portant les rangées de pales de rotor et de stator s'étendent pratiquement radialement et les axes longitudinaux des pales (2, 3) s'étendent pratiquement axialement.
