(JA) 圧縮機
Abstract:
(EN) This hermetic scroll compressor comprises: a hermetic housing; a scroll compressing mechanism housed in the hermetic housing; a discharge cover (3) provided with a discharge port (29) through which a refrigerant compressed by the scroll compressing mechanism passes; a discharge chamber formed between the hermetic housing and the discharge cover (3); an injection tube (50) provided so as to be passed inside the discharge chamber, and within which the refrigerant flows; and a reed valve (40) that is provided to the discharge port (29) of the discharge cover (3), and that is configured such that the refrigerant discharged from the discharge port (29) to the discharge chamber is ejected in a direction separating from the injection tube (50).
(FR) La présente invention concerne un compresseur à spirale hermétique qui comprend : un boîtier hermétique ; un mécanisme de compression à spirale logé dans le boîtier hermétique ; un couvercle de décharge (3) pourvu d’un orifice de décharge (29) à travers lequel un réfrigérant comprimé par le mécanisme de compression à spirale passe ; une chambre de décharge formée entre le boîtier hermétique et le couvercle de décharge (3) ; un tube d’injection (50) disposé de façon à être passé à l’intérieur de la chambre de décharge, et dans lequel le réfrigérant s’écoule ; une soupape flexible (40) qui est disposée sur l’orifice de décharge (29) du couvercle de décharge (3), et qui est configurée de sorte que le réfrigérant déchargé depuis l’orifice de décharge (29) vers la chambre de décharge soit éjecté dans une direction séparée du tube d’injection (50).
(JA) 密閉型スクロール圧縮機は、密閉ハウジングと、密閉ハウジングに収容されたスクロール圧縮機構と、スクロール圧縮機構で圧縮された冷媒が通過する吐出ポート(29)が設けられたディスチャージカバー(3)と、密閉ハウジングとディスチャージカバー(3)との間に形成された吐出チャンバーと、吐出チャンバー内を通過して設けられ、内部を冷媒が流通するインジェクション管(50)と、ディスチャージカバー(3)の吐出ポート(29)に設けられ、吐出ポート(29)から吐出チャンバーへ吐出される冷媒が、インジェクション管(50)から離れる方向に吹き出される構成を有しているリード弁(40)とを備える。
