Abstract (en)

[origin: WO2021078555A1] A displacement pump (1), the principle of which involves sliding vanes (22) into the slots (21) of a rotor (20) in a movement with an axial component. These vanes (22) follow a guide (11), which can be, for example, tracks on flanges (12, 13). Two successive vanes (22) form a cavity, the volume of which varies periodically during the rotation of the rotor (20) by virtue of the sliding of the vanes (22), cyclically causing the fluid to be sucked into, then discharged from, the pump (1).
