(FR) DIFFUSEUR AYANT UN CANAL D'ALIMENTATION EN GAZ, COMPRESSEUR ET CLIMATISEUR
(ZH) 具有供气通道的扩压器、压缩机及空调
Abstract
(EN)
A diffuser (4) having a gas supply channel, a compressor and an air conditioner. The diffuser (4) comprises: a diffuser body; and a first gas supply channel (41), disposed in the diffuser body and used to provide gas to a gas bearing. This solves the problem of gas supply to a gas bearing, stabilizing gas pressure of a thrust bearing location.
(FR)
L'invention concerne un diffuseur (4) ayant un canal d'alimentation en gaz, un compresseur et un climatiseur. Le diffuseur (4) comprend : un corps de diffuseur ; et un premier canal d'alimentation en gaz (41), disposé dans le corps de diffuseur et utilisé pour fournir du gaz à un palier à gaz. Ceci permet de résoudre le problème de l'alimentation en gaz d'un palier à gaz, en stabilisant la pression de gaz d'un emplacement de palier de butée.
