Claims (6)

  1. Compresseur à spirales comprenant :
    un arbre principal (12) qui est prévu avec une douille excentrique (18) et une source d'entraînement (17) configurée pour entraîner en rotation l'arbre principal (12) ;
    une spirale orbitale (20) qui est raccordée en rotation à la douille excentrique (18) de l'arbre principal (12) ;
    une spirale fixe (30) qui fait face à la spirale orbitale (20), formant ainsi une chambre de compression configurée pour comprimer un réfrigérant, et a, à une plaque d'extrémité, un orifice configuré pour décharger le réfrigérant comprimé vers une chambre haute pression ;
    une bague d'Oldham (40) configurée pour limiter le mouvement de la spirale orbitale (20) de sorte que la spirale orbitale (20) est configurée pour tourner sans pivoter par rapport à la spirale fixe (30) ;
    un premier contrepoids (25) configuré pour tourner conjointement avec la douille excentrique (18) ;
    une came excentrique configurée pour tourner conjointement avec la douille excentrique (18) ; et
    un second contrepoids (50), le compresseur à spirales étant caractérisé en ce que le second contrepoids est prévu avec un corps principal (51) et une rainure de came (53) prévue au centre du corps principal (51) et est configurée pour effectuer un mouvement de va-et-vient linéaire à travers la came excentrique par l'entraînement rotatif de l'arbre principal (12) dû à la came excentrique configurée pour agir sur le second contrepoids (50) depuis l'intérieur de la rainure de came (53), de sorte qu'une direction dans laquelle le second contrepoids effectue un va-et-vient linéaire peut être déterminée de manière arbitraire.
  2. Compresseur à spirales selon la revendication 1, dans lequel le premier contrepoids (25) est configuré pour servir de came excentrique,
    le second contrepoids (50) est disposé à l'intérieur de la bague d'Oldham (40), et
    une direction de mouvement de va-et-vient linéaire de la bague d'Oldham (40) et une direction de mouvement de va-et-vient linéaire du second contrepoids (50) sont orthogonales entre elles.
  3. Compresseur à spirales selon la revendication 1, dans lequel la came excentrique est prévue dans une position différente d'un angle de rotation par rapport au premier contrepoids (25), et
    le second contrepoids (50) est disposé à l'intérieur de la bague d'Oldham (40).
  4. Compresseur à spirales selon l'une quelconque des revendications 1 à 3, dans lequel la rainure de came (53) a un axe majeur formé le long d'une direction de côté court du corps principal (51).
  5. Compresseur à spirales selon l'une quelconque des revendications 1 à 4, dans lequel le second contrepoids (50) est prévu avec une paire de griffes (55) et la paire de griffes (55) est montée de manière coulissante dans des rainures qui sont formées dans un palier (14) qui supporte la spirale orbitale (20).
  6. Compresseur à spirales selon la revendication 4 ou 5, dans lequel le premier contrepoids (25) est prévu avec :
    une pièce de raccordement (25a), et
    un corps principal (25b) qui est prévu pour être dressé à partir de la pièce de raccordement (25a), et
    une surface périphérique externe du corps principal (25b) étant configurée pour agir sur le second contrepoids (50) depuis l'intérieur de la rainure de came (53).
