Abstract

L'invention concerne un compresseur à vis comprenant un boîtier extérieur, un boîtier à vis de compresseur, placé dans le boîtier extérieur et dans lequel sont ménagés des alésages de rotor pour des rotors hélicoïdaux, un dispositif d'entraînement placé dans le boîtier extérieur sur un côté du boîtier à vis de compresseur, un logement de palier placé dans le boîtier extérieur sur un côté du boîtier à vis de compresseur, opposé au dispositif d'entraînement, ainsi qu'un silencieux placé à l'intérieur du boîtier extérieur et parcouru par le fluide de travail compressé. Le but de l'invention est d'améliorer le compresseur à vis de sorte que le fluide de travail sortant du compresseur à vis entraîne le moins possible de lubrifiant. A cet effet, le silencieux amène le fluide de travail compressé dans un espace intérieur au moyen d'un écoulement sous la forme d'un flux circulaire s'écoulant autour d'un axe et le lubrifiant se dépose sous l'action de forces centrifuges à partir du flux circulaire du fluide de travail.
