Abstract

L'invention concerne une machine à fluide de type à spirale (1) qui comprend un mécanisme de réglage de contre-pression (72) pour régler la pression d'une chambre de contre-pression (70) en fonction de la différence de pression entre une chambre d'aspiration (42) et la chambre de contre-pression (70). Le mécanisme de réglage de contre-pression (72) comprend une plaque élastique (74), une chambre de plaque (100) formée dans la plaque d'extrémité (40) d'une spirale fixe (36) et contenant la plaque (74), un premier trou de communication (88) destiné à faire communiquer la chambre de plaque (100) et la chambre d'aspiration (42), et un second trou de communication (84) disposé dans la face d'appui (78a) séparant la chambre de plaque (100) et la chambre de contre-pression (70) et destiné à faire communiquer la chambre de plaque (100) et la chambre de contre-pression (70). La plaque élastique (74) s'étend le long de la face d'appui (78a) et est fixée à celle-ci au niveau d'un côté d'extrémité tout en générant une contrainte de flexion, et ferme le second trou de communication (84) par l'appui d'une surface de fermeture (92), formée au niveau de l'autre côté d'extrémité, contre la face d'appui (78a) avec une force élastique prédéterminée générée par la contrainte de flexion.
