Abstract
【解決手段】シリンダ40の内周面40aとロータ50の外周面50aとが回転軸51の軸周りの1周の範囲で最近接する領域(近接部48)に対して、シリンダ40の内周面40aの周方向に沿ってロータ50の回転方向上流側に、圧縮室43で圧縮された冷媒ガスを吐出するための吐出孔を少なくとも2つ有しており、吐出孔のうち近接部48に最も近い側にある第1の吐出孔45aのみに、該吐出孔45aのロータ50の回転方向下流側縁部に切欠き溝部47を形成している。
【選択図】図2
Description
図示のコンプレッサ100は、例えば、冷却媒体の気化熱を利用して冷却を行なう空気調和システム(以下、「空調システム」という)の一部として構成され、この空調システムの他の構成要素である凝縮器、膨張弁、蒸発器等(いずれも図示を省略する)とともに冷却媒体の循環経路上に設けられている。なお、このような空調システムとしては、例えば、車両(自動車など)の車室内の温度調整を行うための空調装置が挙げられる。
次に、シリンダ室42の内周面40aにその周方向に沿って形成された第1、第2の吐出孔45a,45bについて、図2を参照して詳しく説明する。
