    - une deuxième formation étant un soutien extérieur (7) en forme d'une jambe de soutien, et
    - une troisième formation étant la tête d'aspiration (1 a) servant de soutien intérieur.
  2. Dispositif selon la revendication 1, caractérisé en ce que la source de fluide raccordée à l'entrée de fluide (FE) est le seul organe d'entraînement actif du dispositif, pendant que tous les autres éléments du dispositif sont des éléments passifs entraînés par l'énergie de la source de fluide.
  3. Dispositif selon la revendication 1 ou 2, caractérisé en ce qu'un premier moyen de transport de fluide (6) est associé au premier trajet de fluide (6, 8, 9, 10, 12, 4), avec lequel un fluide peut être transporté par le premier trajet de fluide de l'entrée de fluide (FE) vers la tête de buse (1a).
  4. Dispositif selon l'une des revendications 1 à 3, caractérisé en ce qu'un deuxième moyen de transport de fluide (5) est associé au deuxième trajet de fluide (1 a, 14b, 14a, 5), avec lequel un fluide peut être transporté par le deuxième trajet de fluide de la tête d'aspiration (1a) vers la sortie de fluide (FA).
  5. Dispositif selon l'une quelconque des revendications 1 à 4, caractérisé en ce qu'aussi bien le premier moyen de transport de fluide (6) que le deuxième moyen de transport de fluide peut être entraîné par l'énergie, c'est-à-dire par la pression du fluide et/ou le débit du fluide du fluide fourni par la source de fluide raccordée.
  6. Dispositif selon l'une quelconque des revendications 1 à 5, caractérisé en ce que la tête de buse (2a) forme partie d'une chaîne cinématique mécanique (13a, 13b), laquelle comprend une première section pour la transformation d'énergie de pression du fluide en énergie rotative de la chaîne cinématique et ainsi en énergie rotative de la tête de buse.
  7. Dispositif selon l'une des revendications 4 à 6, caractérisé en ce que la tête de buse est disposée dans le deuxième trajet de fluide et est entraînée en aspiration par l'énergie potentielle et/ou cinétique du fluide provenant de la source de fluide raccordable.
  8. Dispositif selon la revendication 7, caractérisé en ce que le deuxième moyen de transport de fluide forme partie de la chaîne cinématique mécanique ou est couplé à celle-ci par entraînement, lequel comprend une deuxième section pour la transformation d'énergie de pression de fluide dans l'énergie d'aspiration de la tête de buse.
  9. Dispositif selon l'une quelconque des revendications 1 à 7, caractérisé en ce que le deuxième moyen de transport (5) fonctionne selon le principe de Venturi, c'est-à-dire une pompe à jet avec une buse d'éjection, le fluide provenant de la source de fluide raccordée formant un jet d'aspiration.
  10. Dispositif selon l'une quelconque des revendications 1 à 9, caractérisé en ce que les éléments montés de manière mobile, en particulier les éléments montés de manière rotative du dispositif comprennent un jeu entre l'élément respectif et le pallier respectif et en ce que le fluide provenant de la source de fluide raccordée agit comme la lubrification du fluide dans la fente qui forme le jeu.
  11. Dispositif selon l'une quelconque des revendications 1 à 10, caractérisé en ce que le premier trajet de fluide (6, 8, 9, 10, 12, 4) et/ou le deuxième trajet de fluide (1 a, 14b, 14a, 5) s'étendent au moins dans une partie du trajet respectif de manière linéaire et sont réglables au niveau de la longueur dans cette partie linéaire.
  12. Dispositif selon la revendication 11, caractérisé en ce que le premier trajet de fluide (6, 8, 9, 10, 12, 4) et le deuxième trajet de fluide (1 a, 14b, 14a, 5) s'étendent au moins dans la partie linéaire (4 resp. 14a) parallèlement l'un à l'autre et sont disposés de préférence de manière concentrique l'un par rapport à l'autre.
  13. Dispositif selon l'une quelconque des revendications 1 à 12, caractérisé en ce que le dispositif comprend une formation (3) munie de préférence d'une ouverture de ventilation, laquelle est fixée à une ouverture du récipient à nettoyer, à la fois le premier trajet de fluide (6, 8, 9, 10, 12, 4) et le deuxième trajet de fluide (1 a, 14b, 14a, 5) s'étendent à travers la formation (3).
  14. Dispositif selon l'une quelconque des revendications 6 à 13, caractérisé en ce qu'une conduite d'aspiration formant le deuxième trajet de fluide (14b, 14a, 5a), laquelle s'étend de la zone d'aspiration (1, 1*) du dispositif à travers le dispositif vers la sortie de fluide (FA) du dispositif, comprend une section inclinée élastique (1 b), et en ce que la chaîne cinématique transférant l'énergie rotative est de préférence également inclinée.
