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 first back pressure chamber (101), a second back pressure chamber (102), a discharge valve (35), a first fixed scroll communication hole (37a), and a second fixed scroll communication hole (37b). In the present invention, the discharge valve (35), which is provided in a second space (S2), inhibits backflow of compressed refrigerant. Additionally, the first fixed scroll communication hole (37a) and the second fixed scroll communication hole (37b) extract one or both of an intermediate refrigerant and the compressed refrigerant from upstream of the discharge valve (35), and guide the refrigerant to the first back pressure chamber (101) and the second back pressure chamber (102).
(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'une première chambre de contre-pression (101), une seconde chambre de contre-pression (102), d'une soupape d'évacuation (35), d'un premier trou de communication à spirale fixe (37a), et d'un second trou de communication à spirale fixe (37b). Dans la présente invention, la soupape d'évacuation (35), qui est disposée dans un second espace (S2), inhibe le reflux du fluide frigorigène comprimé. De plus, le premier trou de communication à spirale fixe (37a) et le second trou de communication à spirale fixe (37b) extraient l'un ou les deux d'un fluide frigorigène intermédiaire et du fluide frigorigène comprimé depuis l'amont de la soupape d'évacuation (35), et guident le fluide frigorigène vers la première chambre de contre-pression (101) et la seconde chambre de contre-pression (102).
(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、第1背圧室(101)及び第2背圧室(102)と、吐出弁(35)と、第1固定スクロール連通孔(37a)及び第2固定スクロール連通孔(37b)とを備える。ここでは、吐出弁(35)は、第2空間(S2)に設けられ、圧縮冷媒の逆流を阻止する。また、第1固定スクロール連通孔(37a)及び第2固定スクロール連通孔(37b)が、中間冷媒及び圧縮冷媒のいずれか一方又は両方を、吐出弁(35)よりも上流側から取り出して、第1背圧室(101)及び第2背圧室(102)に導出する。
