Abstract

L'arbre 4 d'entraînement du piston rotatif 3 traverse une paroi intermédiaire 5, l'étanchéité étant assurée par un joint labyrinthe 12. Un canal d'équilibrage de pression 13 rejoint, à travers la paroi intermédiaire 5, la chambre latérale 7 où se trouve le pignon 9 d'entraînement de l'arbre et un point situé près de la chambre d'aspiration 2 où se trouve le piston rotatif 3.
