Abstract

L'invention concerne une machine volumétrique comportant un arbre principal (13) guidé par rapport à un boîtier (200) de ladite machine volumétrique par un palier avant et un palier arrière situé du côté d'une machine rotative associée, ledit arbre principal étant apte à être accouplé avec un arbre de ladite machine rotative associée. Ladite machine comporte un joint d'étanchéité situé à l'intérieur dudit boîtier et sur ledit arbre principal, entre lesdits paliers, définissant une zone d'accouplement dans laquelle est logé ledit palier arrière, isolée du fluide de travail de ladite machine volumétrique.
