Title
(EN) SCROLL COMPRESSOR
(FR) COMPRESSEUR À VOLUTES
(JA) スクロール圧縮機
Abstract
(EN) A scroll compressor according to this disclosure includes: a partition plate that divides the inside of a closed container into a high-pressure space and a low-pressure space; a non-orbiting scroll that is provided in the low-pressure space; an orbiting scroll that forms a compression chamber between the orbiting scroll and the non-orbiting scroll; and a rotating shaft. The scroll compressor further includes: a main bearing that supports the orbiting scroll; elastic bodies that bias either the non-orbiting scroll or the orbiting scroll in a direction in which the non-orbiting scroll and the orbiting scroll move away from each other; and a plurality of columnar members that are arranged in the circumferential direction such that one end side of each of the plurality of columnar members is affixed and the other end side thereof is movable. Either the non-orbiting scroll or the orbiting scroll biased by the elastic bodies is movable between the partition plate and the main bearing in the axial direction of the rotating shaft. The elastic bodies are disposed between the plurality of columnar members in the circumferential direction.
(FR) La présente invention concerne un compresseur à volutes, lequel compresseur comprend : une plaque de séparation qui divise l'intérieur d'un récipient fermé en un espace haute pression et un espace basse pression ; une volute non orbitale qui est disposée dans l'espace basse pression ; une volute orbitale qui forme une chambre de compression entre la volute orbitale et la volute non orbitale ; et un arbre rotatif. Le compresseur à volutes comprend en outre : un palier principal qui porte la volute orbitale ; des corps élastiques qui sollicitent soit la volute non orbitale soit la volute orbitale dans une direction dans laquelle la volute non orbitale et la volute orbitale se déplacent à l'opposé l'une de l'autre ; et une pluralité d'éléments colonnaires qui sont agencés dans la direction périphérique de telle sorte qu'un côté d'extrémité de chacun de la pluralité d'éléments colonnaires est fixe et que l'autre côté d'extrémité de ce dernier est mobile. Soit la volute non orbitale soit la volute orbitale sollicitée par les corps élastiques est mobile entre la plaque de séparation et le palier principal dans la direction axiale de l'arbre rotatif. Les corps élastiques sont disposés entre la pluralité d'éléments colonnaires dans la direction périphérique.
(JA) 本開示に係るスクロール圧縮機は、密閉容器内を高圧空間と低圧空間とに区画する仕切板と、低圧空間に設けられた非旋回スクロールと、非旋回スクロールとの間に圧縮室を形成する旋回スクロールと、回転軸と、を備えている。さらに、旋回スクロールを支持する主軸受と、非旋回スクロールと旋回スクロールを離間させる方向に、いずれか一方を付勢する弾性体と、一端側が固定、他端側が移動自在に、かつ、周方向に配設される複数の柱状部材と、を備えている。弾性体によって付勢された非旋回スクロールおよび旋回スクロールのいずれか一方は、仕切板と主軸受との間で、回転軸の軸方向に移動自在である。弾性体は、周方向において複数の柱状部材の間に配置されている。
