<p>A fluid machine includes: a casing (1) with internal cavity (2), and axis (3), about which the cavity (2) is symmetrical and two sections (4, 4a), respectively for the infeed into and discharge from the cavity (2) of the fluid; a pair of vanes (5, 6), positioned in the cavity (2) in such a way that they divide it into a corresponding pair of separate chambers (7, 8) designed to alternately receive and discharge the fluid. The vanes (5, 6) are mounted in the casing (1): in such a way that they can turn about the axis (3), and independently, so that one (5, 6) moves relative to the other (6, 5) to cause a corresponding variation in the volumes of the chambers (7, 8) between them. The machine (20) includes drive means (21, 12a, 12b, 14a, 14b) designed to cause the vanes (5, 6) to turn at a cyclically variable speed, and being timed differently for each of the vanes (5, 6) so as to cause variations in the volumes of the chambers (7, 8) suited to the changes in state of the fluid. <IMAGE> <IMAGE></p> |
