Title (EN) VANE-TYPE AIR MOTOR
(FR) MOTEUR PNEUMATIQUE DU TYPE À PALETTES
(JA) ベーン式エアモータ
Abstract:
(EN) Disclosed is a vane-type air motor constituted to prevent irregular wear of the vanes. The air motor [A1] comprises a cylindrical body with a rotor chamber (19) delimited by a cylindrical inner circumferential surface (11), and a vaned rotor. A multiplicity of air discharge openings (50) is disposed across a range of set length in the axial direction of the rotor chamber, with spacing set between adjacent air discharge openings in the axial direction, and arranged to overlap with one another when viewed in said circumferential direction. [A1]Client: There is no subject in the second sentence.
(FR) L'invention concerne un moteur pneumatique du type à palettes constitué pour empêcher toute usure irrégulière des palettes. Le moteur pneumatique [A1] comporte un corps cylindrique ayant une cuve de rotor (19) que délimite une surface circonférentielle intérieure cylindrique (11), et un rotor à palettes. Une multiplicité d'ouvertures de décharge d'air (50) se trouvent en travers d'une longueur définie dans le sens axial de la cuve de rotor, des espaces étant définis entre des ouvertures de décharge d'air adjacentes dans le sens axial, et disposées pour se chevaucher les unes par rapport aux autres quand observées dans ledit sens circonférentiel.
(JA) 【課題】ベーンの不均一に磨耗を防止するようにしたベーン式エアモータを提供する。 【課題解決のための手段】 円筒状内周面(11)によって画定されるロータ室(19)を有する筒状体と、ベーン付きロータとを有する。空気排出開口が(50)が、ロータ室の軸線方向の一定長さ範囲にわたって複数設けられ、軸線方向で隣接する空気排出開口が相互に間隔をあけられ、且つ、該円周方向で見て、相互にオーバーラップされるように配置される。
