Claims (8)

  1. Un compresseur rotatif comprenant un boîtier de corps (10), dans lequel se trouvent : un moteur de compresseur (30), un mécanisme de compression (20) entraîné par ledit moteur de compresseur (30), et une cloison (23) divisant l'intérieur dudit corps (10) en un espace de haute pression et un espace de basse pression, ledit corps (10) possédant un fourreau (11) de forme cylindrique et une plaque d'extrémité (12) fixée solidement audit fourreau (11) par soudage,
    caractérisé en ce que
    ladite cloison (23) est façonnée afin d'être emboutie sur ledit corps (10) sur une zone de soudure où ledit fourreau (11) et ladite plaque d'extrémité (12) sont soudés l'un à l'autre, et possède un collier (41) faisant saillie radialement vers l'extérieur de façon à faire butée contre une surface supérieure du fourreau (11) ;
    ladite plaque d'extrémité (12) étant configurée afin de faire butée contre une surface supérieure dudit collier (41), et devant être ajustée avec jeu sur le fourreau (11) et ladite cloison (23) ; et
    une cannelure périphérique (42) s'étendant en continu dans une direction circonférentielle pour tenir compte du rétrécissement dudit corps (10) causé par le soudage sur ladite zone de soudure dudit fourreau (11), et ladite plaque d'extrémité (12) étant formée dans une surface périphérique externe (40) de ladite cloison (23).
  2. Le compresseur rotatif selon la revendication 1, dans lequel :
    une saillie (45)(46, 47) s'étendant de façon continue dans une direction circonférentielle en un point situé à proximité de ladite cannelure périphérique (42) est formée dans ladite surface périphérique externe (40) de ladite cloison (23), et
    ladite saillie (45)(46, 47) est façonnée de façon à pouvoir être emboutie dans ledit corps (10).
  3. Le compresseur rotatif selon la revendication 1, caractérisé en ce que :
    ladite cloison (23) est façonnée de façon à pouvoir être ajustée avec jeu, et non pas emboutie, sur ledit corps (10) en une zone de soudure où ledit fourreau (11) et ladite plaque d'extrémité (12) sont soudés ensemble
    et, en outre, une saillie (45)(46, 47) s'étendant de façon continue dans une direction circonférentielle en un point situé à proximité de ladite cannelure périphérique (42) est formée dans ladite surface périphérique externe (40) de ladite cloison (23), et ladite saillie (45)(46, 47) est façonnée de façon à pouvoir être emboutie dans ledit corps (10).
  4. Le compresseur rotatif selon la revendication 2 ou la revendication 3, dans lequel ladite saillie (46, 47) de ladite cloison (23) est prévue dans une série d'emplacements.
  5. Le compresseur rotatif selon la revendication 4, dans lequel des saillies (46, 47) se distinguent les unes des autres par la hauteur de la saillie.
  6. Le compresseur rotatif selon la revendication 2 ou la revendication 3, dans lequel un bout, ou les deux bouts (45a, 45b), de ladite saillie (45)(46, 47) relativement à la direction axiale de ladite cloison (23) sont façonnés en une surface conique.
  7. Le compresseur rotatif selon la revendication 2 ou la revendication 3, dans lequel :
    la cloison (23) possède des parties épaisses et minces (43) et (44) de différentes épaisseurs relativement à une direction radiale, et
    ladite saillie (45)(46, 47) est façonnée dans un pourtour extérieur de ladite pièce épaisse (43).
  8. Le compresseur rotatif selon la revendication 1 à 3, dans lequel :
    ledit mécanisme de compression (20) est composé d'un mécanisme de compression (20) du type à volute, et
    ladite cloison (23) est façonnée de sorte qu'une volute fixe (21) est fixée solidement à ladite cloison (23).
