Abstract

Pompe à rotor à lobes. Cette pompe comporte une chambre 2 munie d'une entrée et d'une sortie de fluide, des rotors à lobes 5 montés à pivotement à l'intérieur de cette chambre et une soupape de décompression; cette dernière comporte une membrane 6 qui constitue au moins une partie de la paroi extrême de la chambre 2 et qui peut se déplacer élastiquement dans la direction longitudinale des rotors 5 de façon à abaisser toute pression de fluide en excès à une valeur prédéterminée. Pompe à soupape de décompression utilisable pour déplacer des liquides.
