Title (EN) SCROLL COMPRESSOR
(FR) COMPRESSEUR À SPIRALE
(JA) スクロール圧縮機
Abstract:
(EN) Provided is a scroll compressor having high compression efficiency. A scroll compressor (10) is provided with a casing (20), a scroll compression mechanism (60), a housing (61), a floating member (65), a first back pressure chamber (101), and a second back pressure chamber (102). The first back pressure chamber (101) and the second back pressure chamber (102) push the floating member (65) against a movable scroll (40), using one or both of an intermediate refrigerant being compressed by a compression chamber (Sc) and compressed refrigerant discharged from the compression chamber, to thereby push the movable scroll (40) against a fixed scroll (30).
(FR) La présente invention concerne un compresseur à spirale présentant un rendement de compression élevé. Un compresseur à spirale (10) est pourvu d'un carter (20), d'un mécanisme de compression à spirale (60), d'un logement (61), d'un élément flottant (65), d'une première chambre de contre-pression (101) et d'une seconde chambre de contre-pression (102). La première chambre de contre-pression (101) et la seconde chambre de contre-pression (102) poussent l'élément flottant (65) contre une volute mobile (40), à l'aide d'un ou des deux parmi un fluide frigorigène intermédiaire comprimé par une chambre de compression (Sc) et un fluide frigorigène comprimé évacué de la chambre de compression, pour ainsi pousser la spirale mobile (40) contre une spirale fixe (30).
(JA) 圧縮効率の高いスクロール圧縮機を提供する。 スクロール圧縮機(10)は、ケーシング(20)と、スクロール圧縮機構(60)と、ハウジング(61)と、フローティング部材(65)と、第1背圧室(101)及び第2背圧室(102)とを備える。第1背圧室(101)及び第2背圧室(102)は、圧縮室(Sc)で圧縮されている途中の中間冷媒及び圧縮室から吐出される圧縮冷媒のいずれか一方又は両方を用いてフローティング部材(65)を可動スクロール(40)に押し付けることで、可動スクロール(40)を固定スクロール(30)に押し付ける。
