Title (EN) ROTARY COMPRESSOR
(FR) COMPRESSEUR ROTATIF
Abstract:
(EN) The present disclosure may provide a compressor in which an outer circumferential side cross-sectional area of a vane slot is formed to be smaller than an inner circumferential side cross-sectional area thereof to decrease an area receiving a force in a roller direction by a vane so as to reduce a contact force between the roller and the vane, and a gas accommodation portion capable of selectively forming a suction pressure and an intermediate pressure is formed between the vane and the vane slot to appropriately control a contact force between the vane and the roller, and a contact surface of the vane facing the roller is broadly formed at a side of a compression chamber to appropriately reduce a contact force between the roller and the vane, and a space portion forming a discharge pressure is formed at least either one side of a side surface of the vane and a cylinder corresponding thereto to decrease a side directional reaction force applied to the vane, thereby reducing a mechanical friction loss between the vane and the cylinder.
(FR) La présente invention concerne un compresseur, dans lequel une surface de section transversale de côté périphérique externe d'une fente d'aube est formée de manière à être inférieure à une surface de section transversale de côté périphérique interne de cette dernière pour diminuer une surface recevant une force dans une direction de rouleau par une aube de manière à réduire une force de contact entre le rouleau et l'aube, et une partie de réception de gaz apte à former de façon sélective une pression d'aspiration et une pression intermédiaire est formée entre l'aube et la fente d'aube pour commander de manière appropriée une force de contact entre l'aube et le rouleau, et une surface de contact de l'aube faisant face au rouleau est grossièrement formée sur un côté d'une chambre de compression afin de réduire de manière appropriée une force de contact entre le rouleau et l'aube, et une partie d'espacement formant une pression d'évacuation est formée sur au moins l'un ou l'autre côté d'une surface latérale de l'aube et d'un cylindre correspondant à cette dernière afin de réduire une force de réaction de direction latérale appliquée à l'aube, de façon à réduire ainsi une perte par frottement mécanique entre l'aube et le cylindre.
