<p>The invention concerns a rotary pump comprising: a stator (1) penetrated by a housing (11) delimited by a cylindrical lateral wall (110); a cylindrical rotor (2) tangential to the interior of the housing (11) and rotatably drivable about an axis (X) which is eccentric relative to this housing; and a vane (3) passing diametrically through the rotor and having two opposite edges (31, 32) bearing against the lateral housing wall (110) and separated from each other by a distance which can vary as the rotor rotates. According to the invention, the vane (3) is made from a sheet of material which offers resilient resistance to flexion and has an undulating part (33, 34) enabling the variations in the distance between the opposite vane edges (31, 32) to be absorbed.</p> |
