The invention relates to a rotor (2) for a rotary machine and to a rotary machine equipped with said rotor, wherein the rotor (2) revolves in a gaseous or liquid medium and has, at least on one of its lateral surfaces (4), a profile (3) with at least one convex elevation (19) for producing a pressure difference. This rotor (2) is characterized by the fact that the convex elevation (19) is formed as an airfoil profile (3) of an aircraft, and the rotor (2) has an axial cavity (6) on the inside. In this case, the rotor (2) is connected to at least one chamber (12, 21) for guiding the medium provided in or away, wherein at least one passage opening (5) is provided between the cavity (6) and the outer lateral surface (4) in the region of the airfoil profile (3). Such a rotor (2) within different housing formations (7) forms a rotary machine, which can be used as a pump, a compressor, a condenser, a blower, a turbomachine, a turbine or as a pressure neutralizer.
Rotor (2) pour une turbomachine et turbomachine pourvue dudit rotor. Ce rotor (2) tourne dans un milieu gazeux ou liquide et comporte au moins sur une de ses surfaces périphériques (4) un relief (3) pourvu d'au moins une élévation convexe (19) destinée à produire une différence de pression. Ce rotor (2) est caractérisé en ce que l'élévation convexe (19) est conçue comme un relief (3) à surface portante d'avion, et ledit rotor (2) possède une cavité axiale interne (6). Le rotor (2) est raccordé à au moins une chambre (12, 21) destinée à l'introduction ou à l'évacuation du milieu, et au moins un passage traversant (5) est ménagé entre la cavité (6) et la surface périphérique externe (4) dans la zone du relief (3) à surface portante. Un rotor (2) de ce type situé à l'intérieur de carters (7) de configurations diverses forme une turbomachine qui peut être utilisée en tant que pompe, compresseur, soufflante, turbomachine, turbine ou en tant que neutraliseur de pression.
