Title (EN) ROTARY COMPRESSOR AND REFRIGERATION CYCLE DEVICE
(FR) COMPRESSEUR ROTATIF ET DISPOSITIF À CYCLE DE RÉFRIGÉRATION
(JA) 回転式圧縮機及び冷凍サイクル装置
Abstract:
(EN) The rotary compressor of an embodiment is provided with a container, a cylinder, closure plates, a roller, and a blade. The cylinder is accommodated within the container and has openings. The closure plates close the openings of the cylinder and form a cylinder chamber in cooperation with the cylinder. The blade is accommodated within a blade groove formed in the cylinder and can move into and out of the cylinder chamber as the roller eccentrically rotates. The blade has a base material and a coating. The coating has higher hardness than the base material and covers at least the groove facing surfaces of the outer surface of the base material, the groove facing surfaces being located outside closure plate facing surfaces which face the closure plates and facing the inner surfaces of the blade groove.
(FR) Un mode de réalisation de l'invention concerne un compresseur rotatif, qui comprend un récipient, un cylindre, des plaques de fermeture, un rouleau et une pale. Le cylindre est reçu à l'intérieur du récipient, et a des ouvertures. Les plaques de fermeture ferment les ouvertures du cylindre et forment une chambre de cylindre en coopération avec le cylindre. La pale est reçue à l'intérieur d'une rainure de pale formée dans le cylindre et peut se déplacer de façon à rentrer dans la chambre de cylindre et à sortir de cette dernière quand le rouleau tourne de manière excentrée. La pale a un matériau de base et un revêtement. Le revêtement a une dureté supérieure à celle du matériau de base et recouvre au moins les surfaces faisant face à la rainure de la surface externe du matériau de base, les surfaces faisant face à la rainure étant disposées à l'extérieur de surfaces faisant face aux plaques de fermeture, qui font face aux plaques de fermeture et qui font face aux surfaces internes de la rainure de pale.
(JA) 実施形態の回転式圧縮機は、容器と、シリンダと、閉塞板と、ローラと、ブレードと、を備える。シリンダは、容器内に収納され、開口部を有する。閉塞板は、シリンダの開口部を閉塞して、シリンダとともにシリンダ室を形成する。ブレードは、シリンダに形成されたブレード溝内に収容され、ローラの偏心回転に伴いシリンダ室内に進退可能とされる。ブレードは、基材と被膜とを持つ。被膜は、基材よりも硬度が高く、基材の外面のうち、閉塞板と対向する閉塞板対向面以外の部分であって、少なくともブレード溝の内面と対向する溝対向面を被覆する。
