    - un axe de rotation central (2, 2.1),
    - un moyeu rotatif (26, 26.1) et
    - des éléments du genre ailettes (30 - 45, 50 - 55), qui sont fixés extérieurement à déplacement sur le moyeu,
    caractérisée en ce que
    - les éléments (30 - 45, 50 -55) sont chacun constitués de plusieurs maillons (63 - 65) mobiles les uns par rapport aux autres.
  2. Roue de soufflante selon la revendication 1,
    caractérisée en ce que
    - elle (23.1) est entourée par une paroi (5) d'un carter (1.1) disposée concentriquement à son axe de rotation (2.1) et
    - ses éléments (30 - 45, 50 -55) s'étendent presque jusqu'à la paroi (5) lors de la rotation autour de l'axe de rotation (2.1).
  3. Roue de soufflante selon la revendication 1 ou 2, caractérisée en ce que les éléments (30 - 45, 50 -55) sont répartis sur la périphérie du moyeu (26, 26.1), notamment uniformément répartis.
  4. Roue de soufflante selon l'une des revendications précédentes, caractérisée en ce que plusieurs éléments (30 - 45, 50 - 55) sont accrochés extérieurement au moyeu (26, 26.1), qui sont chacun constitués de plusieurs maillons (61 - 65) accrochés les uns aux autres en mobilité relative à la manière de maillons de chaîne.
  5. Roue de soufflante selon l'une des revendications précédentes, caractérisée en ce que les éléments (30 - 45, 50 -55) sont disposés en deux ou plus de deux couronnes (46, 46.1, 47, 47.1), chaque couronne étant constituée de plusieurs éléments (30 - 45, 50 - 55) disposés à la même hauteur axiale en étant répartis sur la périphérie.
  6. Roue de soufflante selon l'une des revendications précédentes, caractérisée en ce que, pour une tête à maillons (23) qui possède plusieurs couronnes (46, 47), au moins deux couronnes (46, 47) sont mutuellement accouplées et reliées à déplacement par des éléments plats (27 - 29).
  7. Roue de soufflante selon l'une des revendications précédentes, caractérisée en ce qu'un élément (50 - 55) est constitué d'anneaux plats (61 - 65) qui sont enchaînés en étant chaque fois, en ce qui concerne leur développement à plat, tournés de 90° par rapport à l'anneau voisin.
  8. Roue de soufflante selon l'une des revendications précédentes, caractérisée ce que les anneaux chaque fois les plus intérieurs (61) sont disposés, en ce qui concerne leur développement à plat, parallèlement à l'axe (2, 2.1) de la tête à maillons.
  9. Roue de soufflante selon l'une des revendications précédentes, caractérisée en ce qu'un ou plusieurs anneaux (63) ne sont ouverts que pour fournir l'espace libre nécessaire pour l'accrochage des anneaux voisins (62, 64), mais sont au reste fermés sur leur surface.
  10. Roue de soufflante selon la revendication 2, caractérisée en ce que, dans la région de la roue, la paroi (5) du carter (1.1) se rétrécit coniquement en direction du côté d'aspiration des gaz, de préférence de 45 degrés, et en ce qu'ensuite, en direction de l'ouverture de sortie (4.1), la paroi (3.1) se poursuit concentriquement vers l'axe de rotation (2.1) de la tête à maillons (23.1), et une surface de chicane (8) est disposée du côté du flux sortant, laquelle recouvre pratiquement totalement la tête à maillons à distance axiale.
  11. Roue de soufflante selon l'une des revendications précédentes, caractérisée en ce que des éléments (31 - 35) sont présents, qui possèdent des maillons (27 - 29) qui, en coupe transversale, sont courbés vers l'avant (27) ou vers l'arrière (28) dans la direction de rotation (25), ou sont droits (29).
