Abstract

L'invention concerne un compresseur du type spirale comprenant une partie spirale (2) fixe et une partie spirale (4) en orbite dotées d'enveloppes de spirale faisant saillie à partir de plaques d'extrémité qui coopèrent l'une avec l'autre afin de former une chambre de compression (5) entre lesdites parties. Le compresseur exécute une aspiration, une compression et une décharge lorsque la chambre de compression (5) se déplace tout en faisant varier son volume, ce déplacement se produisant lorsque la partie spirale (4) en orbite se met en orbite sur un chemin circulaire tout en étant restreinte en rotation au moyen d'un mécanisme de restreinte de rotation. Un évidement (14) est prévu dans une face d'extrémité d'enveloppe (4a) sur le côté opposé de la plaque d'extrémité (4b). Un chemin de connexion (15) destiné à connecter l'évidement (14) et une face arrière de la plaque d'extrémité (4b) est formé.
