Title
(EN) ROTARY VANE PUMP
(FR) POMPE ROTATIVE A PALETTES
Abstract
(EN)
A rotary vane pump comprising a housing (12) having an inner cam surface (30) defining a chamber and an inlet and an outlet port establishing fluid communication. A plurality of vanes are arranged substantially radially about a central vane axis of rotation. A rotatable carousel rotor (34) is positioned on a drive axis disposed a predetermined distance from the central vane axis. The carousel has slot members positioned in it for reciprocally carrying each vane during the rotation of the vane. A one-piece central rotor (70) gear is rotatably mounted on the central axis for pivotally coupling each vane at a point offset from the vane axis to establish rocking lever action between the carousel and the vanes upon rotation of the vanes.
(FR)
Pompe rotative à palettes comprenant un carter (12) comportant une face interne de came (30) définissant une chambre et un orifice d'admission et un orifice de refoulement établissant la communication fluidique. Plusieurs palettes sont disposées selon une configuration essentiellement radiale par rapport à l'axe central de rotation des palettes. Un rotor à plateau tournant (34) est placé sur un axe d'entraînement situé à une distance prédéterminée de l'axe central des palettes. Ce plateau tournant comporte des fentes conçues pour porter avec un mouvement alternatif chacune des palettes au cours de la rotation de ces dernières. Un rotor central monobloc (70) est monté pivotant sur l'axe central de manière à raccorder tout en permettant un mouvement rotatif chacune des palettes selon un point décalé par rapport à l'axe de celles-ci afin de déterminer un mouvement de balancement entre le plateau tournant et les palettes au cours de la rotation de celles-ci.
