The invention relates to a single-winged vacuum pump provided with a pot- shaped housing (12), a rotor (18) which is mounted in a rotational and eccentric manner in the housing, a wing (20) which is displacably mounted in the rotor and which is orthogonal to the rotational axis, whereby the points of the wings are placed on the peripheral surface (22) which defines a work chamber (30) and which subdivides the work chamber into a suction chamber (40) and a pressure chamber (42), and the suction chamber is provided with an air inlet and the pressure chamber is provided with an air outlet (48). The air outlet is arranged in the peripheral surface surrounding the pressure chamber (42).
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) qui est logée mobile dans le rotor orthogonalement à l'axe de rotation, dont les pointes s'appuient contre une surface périphérique (22) délimitant un espace de travail (30) et qui subdivise, ce faisant, l'espace de travail en une chambre d'aspiration (40) et en une chambre de pression (42), la chambre d'aspiration étant munie d'un orifice d'entrée d'air et la chambre de pression d'un orifice de sortie d'air (48). Selon l'invention, l'orifice de sortie d'air est placé dans la surface périphérique entourant la chambre de pression (42).
