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.
