Claims (4)
上記第1及び第2の蓋部材の少なくとも一方に上記シリンダ室内で圧縮された冷媒を吐出する吐出孔を設け、
この吐出孔を、上記ブレードが下死点に位置するときの上記圧縮室の断面積をB(m2)、上記吐出孔の断面積をC(m2)としたとき、C/B≦0.15となるように設定するとともに、上記吐出孔の長さを3mm以下にし、上記吐出孔がシリンダ室に臨む面積の割合を吐出孔の断面積の87%以上とするとともに、上記シリンダには冷媒吐出用の切欠き溝を設けないことを特徴とする密閉型回転式圧縮機。 An electric motor unit and a rotary compression mechanism unit coupled to the motor unit via a rotating shaft are accommodated in a sealed case, and the rotary compression mechanism unit includes a cylinder forming a cylinder chamber, and both end surfaces of the cylinder. A hermetic rotary compressor provided with first and second lid members that cover the cylinder chamber, and rollers and blades that separate the cylinder chamber into a compression chamber and a suction chamber;
A discharge hole for discharging the refrigerant compressed in the cylinder chamber is provided in at least one of the first and second lid members,
The discharge hole, the cross-sectional area of the compression chamber B (m 2) when the upper Symbol blade is positioned at the bottom dead center, when the cross-sectional area of the discharge hole was C (m 2), C / B ≦ The discharge hole length is set to 3 mm or less, and the ratio of the area where the discharge hole faces the cylinder chamber is set to 87% or more of the cross-sectional area of the discharge hole. Is a hermetic rotary compressor characterized by not having a notch for discharging refrigerant.
