Abstract

Compresseur, comprenant : un arbre principal (1), un cylindre pneumatique (2), une bride (3) et des pièces coulissantes (4). L'arbre principal (1) comprend une partie saillante (11). La partie saillante (11), le cylindre pneumatique (2), la bride (3) et les pièces coulissantes (4) forment ensemble des cavités de compression (100). Au moins un orifice d'échappement d'arbre principal (5) est disposé sur la partie saillante (11) pour chaque cavité de compression correspondante (100). Un orifice d'échappement de bride (6) est disposé sur la bride (3). Une extrémité de chaque orifice d'échappement d'arbre principal (5) communique avec la cavité de compression (100), et l'autre extrémité communique avec l'orifice d'échappement de bride (6) pendant un processus de rotation de l'arbre principal (1) de manière à évacuer un gaz. Un ensemble soupape d'échappement (7) est disposé à l'intérieur de l'orifice d'échappement d'arbre principal (5). L'ensemble soupape d'échappement (7) comprend une plaque de blocage (73), un bloc de soupape (71) et un élément élastique (72). La plaque de blocage (73) est intégrée dans un trou d'échappement radial (51) à partir d'une surface d'extrémité de la partie saillante (11). L'ensemble soupape d'échappement (7) est apte à évacuer automatiquement un gaz en fonction de la quantité de pression dans la cavité de compression (100). Un climatiseur comprenant ledit compresseur est également fourni. La conception structurale dudit compresseur assure efficacement un nombre fixe et une zone fixe d'orifices d'échappement dans chaque cavité de compression, ce qui répond aux exigences de vitesse d'échappement du compresseur tout en assurant également un fonctionnement normal du compresseur dans toutes les conditions de travail et un changement continu de la vitesse d'échappement.
