Title (EN) SCROLL COMPRESSOR AND REFRIGERATION CYCLE DEVICE
(FR) COMPRESSEUR À SPIRALE ET DISPOSITIF À CYCLE FRIGORIFIQUE
(JA) スクロール圧縮機および冷凍サイクル装置
Abstract:
(EN) This scroll compressor is provided with a discharge valve mechanism disposed on a discharge chamber side of a fixed scroll, wherein the discharge valve mechanism has a lead valve, and has a valve seat which is provided on a surface on the discharge chamber side of the fixed scroll and on which the lead valve is seated around a discharge port that is open in the center portion. One or more cutouts are formed in the edge of the valve seat.
(FR) L'invention concerne un compresseur à spirale pourvu d'un mécanisme de soupape de refoulement disposé côté chambre de refoulement d'une spirale fixe, le mécanisme de soupape de refoulement comportant une soupape principale, et comportant un siège de soupape qui est disposé sur une surface côté chambre de refoulement de la spirale fixe et sur lequel la soupape principale est placée autour d'un orifice de refoulement qui est ouvert dans la partie centrale. Une ou plusieurs découpes sont formées sur le bord du siège de soupape.
(JA) スクロール圧縮機は、固定スクロールの吐出チャンバ側に配置される吐出弁機構を備え、前記吐出弁機構は、リード弁と、前記固定スクロールの吐出チャンバ側での表面に設けられ、中央部に開く吐出口周りにて前記リード弁が着座する弁座と、を有するスクロール圧縮機であって、前記弁座の縁部には、1つ以上の切欠きが形成される。
