Abstract

L'invention concerne un boîtier intégré à structure de séparation de l'huile destiné à un compresseur alternatif qui comprend un boîtier comportant une chambre d'aspiration et une chambre de d'évacuation, un bloc de cylindre couplé au boîtier et plusieurs alésages de cylindre, des pistons disposés en va-et-vient dans ces alésages de cylindre, des moyens d'entraînement des pistons destinés à entraîner les pistons, et un appareil à soupape placé à l'opposé des fonds des pistons et équipé d'un port d'aspiration et d'un port d'évacuation en communication avec la chambre d'aspiration et la chambre d'évacuation. Ce boîtier est caractérisé en ce que: la structure de séparation de l'huile possède un retrait intérieur doté d'un port d'évacuation de gaz formé dans son fond, un retrait périphérique formé autour du retrait intérieur en communication avec la chambre d'évacuation et un port d'évacuation d'huile en communication avec le retrait intérieur de manière circulante, lesquels ne forment qu'une seule pièce; et la chambre d'évacuation plutôt que la chambre d'aspiration est placée à proximité du centre de celle-ci. C'est pourquoi, étant donné que l'huile est séparée du refroidisseur introduit dans la chambre d'évacuation, puis réutilisé, il est possible d'augmenter l'efficacité et de conserver la durabilité du compresseur. En outre, étant donné que la structure de séparation de l'huile ne forme qu'une seule pièce avec le boîtier, il n'est pas nécessaire de fournir un composant séparer pour séparer l'huile, et le boîtier peut être facilement formé ce qui réduit son coût de production.
