Abstract

組み立てが容易で、かつメカニカルシールの接触摺動部から漏出する潤滑油を速やかに排出し、固定環周辺での油のスラッジ化を防止することができる冷媒圧縮機を提供する。回転軸（２５）が貫通する部分にハウジング（２）の内部側と外部側とを軸封するメカニカルシール（３０）が設置される冷媒圧縮機（１）において、メカニカルシール（３０）は、ボス部（７Ａ）の内周面に固定設置される固定環（４１）と、固定環（４１）の内部側に固定環と対向されて回転軸（２５）の外周面に固定設置され、固定環（４１）との互いに対向する側面間に接触摺動部が形成される回転環（４４）とを備え、固定環（４１）よりも外部側のボス部（７Ａ）の内周面には、該内周面の全部または少なくとも重力方向下側の一部を、固定環（４１）側からその外部側の油排出孔（５１）に向って漸次拡大する傾斜部（４９Ａ）が設けられる。
