Abstract

Dans le compresseur à spirale à double rotation de l'invention, sont agencés un élément spirale côté entraînement (70), un élément côté entraîné (90), et une partie admission de spirale (3b) qui admet un premier élément support (33) ainsi qu'un second élément support (35). Une première partie spirale côté entraînement (71) et une seconde partie spirale côté entraînement (72) sont fixées au moyen d'un boulon de fixation de paroi (31). L'élément côté entraîné (90) et le second élément support (35) sont fixés au moyen d'un second boulon de fixation de support (36). Un orifice d'accès (3b1) permettant d'accéder au boulon de fixation de paroi (31) et au boulon de fixation de support (36), est formé dans la partie admission de spirale (3b).
