Abstract

L'invention concerne un groupe compresseur de réfrigérant. Le groupe est caractérisé par une valve qui ferme normalement l'ouverture de vidangé et s'ouvre quand la pression dans le bloc cylindre dépasse la pression agissant sur la surface de l'huile pour permettre à l'huile de retourner du bloc cylindre à la cuve à huile par l'ouverture de vidange. Application à la fabrication des compresseurs
