Abstract

La présente invention concerne un raccord de fluide contenant une unité mécanique de régulation de vitesse sans alimentation électrique et destiné à une pompe, dans lequel, afin de compenser une variation de pression d'eau refoulée selon une variation du débit de refoulement de la pompe, le raccord de fluide détecte une variation de la pression de refoulement de la pompe et règle le nombre de rotations du raccord de fluide relié à l'arbre d'entrée du côté pompe, par l'intermédiaire de celui-ci. Le raccord de fluide comprend un boîtier de raccord de fluide, un réservoir de fluide de circulation intégré d'un seul tenant dans le boîtier, et une unité de commande mécanique ; le boîtier de raccord de fluide comporte une forme d'aile sur l'extérieur de celui-ci pour maximiser la quantité de chaleur évacuée dans l'atmosphère par le refroidissement d'un fluide de travail, et fait partiellement circuler un fluide du côté de sortie de la pompe afin de satisfaire les performances de refroidissement de celle-ci. Par conséquent, ce raccord de fluide présente une durabilité semi-permanente sans utiliser d'énergie électrique pour une commande séparée.
