Abstract

Pompe volumétrique (1) dont le principe comprend de faire coulisser des palettes (22) dans des encoches (21) d’un rotor (20) selon un mouvement ayant une composante axiale. Ces palettes (22) suivent un guide (11), qui peut par exemple être des pistes sur des flasques (12, 13). Deux palettes (22) successives forment une cavité dont le volume varie périodiquement au cours de la rotation du rotor (20) grâce au coulissement des palettes (22), induisant de manière cyclique une aspiration du fluide dans la pompe (1) puis un refoulement.Positive displacement pump (1), the principle of which comprises sliding vanes (22) in notches (21) of a rotor (20) according to a movement having an axial component. These pallets (22) follow a guide (11), which can for example be tracks on flanges (12, 13). Two successive vanes (22) form a cavity whose volume varies periodically during the rotation of the rotor (20) thanks to the sliding of the vanes (22), cyclically inducing a suction of the fluid in the pump (1) then a discharge. .
