Abstract

Soupape de retenue pour pompe à gaz à anneau liquide, destinée à recouvrir et à libérer, en fonction de la pression, des ouvertures de sortie de pression d'un disque de distribution, qui sépare l'enceinte de travail de la pompe de la chambre d'aspiration et de la chambre de refoulement du corps. Elle est formée de plusieurs languettes 18a à 18e flexibles et indépendantes l'une de l'autre dans leur mouvement, qui recouvrent chacune un nombre déterminé d'ouvertures de sortie de pression 17a à 17e et dont chacune est réunie rigidement au disque de distribution 10 à l'une de ses extrémités, tandis que son autre extrémité peut s'écarter de façon limitée du disque de distribution.
