The invention relates to a single-winged vacuum pump provided with a pot-
shaped housing (12), a rotor (18) which is rotationally and eccentrically
mounted in the housing, a wing (20) which is displacably mounted in the rotor
and orthogonal on the rotational axis and a work chamber (22) which receives
the wing (20) and which comprises an internal peripheral surface (30) whereon
both of the sealing edges (68), which are arranged opposite to each other of
the wing, are arranged. The wing (20) subdivides the work chamber into a
suction chamber (30) and a pressure chamber and the end (28) of the wing,
which is oriented towards the internal peripheral surface (30), comprises a
flattened section (66) on the side oriented towards the pressure chamber (26).
L'invention concerne une pompe à vide à une ailette, qui comprend un carter (12) en forme de creuset, un rotor (18) monté de manière rotative et excentrique dans le carter, une ailette (20) logée mobile dans le rotor orthogonalement à l'axe de rotation, ainsi qu'un espace de travail (22) recevant l'ailette (20) et muni d'une surface périphérique intérieure (30) contre laquelle s'appuient les deux arêtes d'étanchéité (68) opposées l'une à l'autre de l'ailette. Selon l'invention, l'ailette (20) subdivise l'espace de travail en une chambre d'aspiration (24) et en une chambre de pression et l'extrémité (28), dirigée vers la surface périphérique intérieure (30), de l'ailette présente un segment aplati (66) sur sa face orientée vers la chambre de pression (26).
