Abstract

　本発明は、バイパス通路を介して圧縮室内の冷媒の一部を排出させて容量を可変とした圧縮機構を備える圧縮機に関するものである。 　圧縮室に開口するバイパス通路の開口面積を十分に確保する。 　圧縮機（20）は、低段側シリンダ（41a）と低段側ピストン（47a）とを有して低段側シリンダ室（42a）の冷媒を圧縮する低段側圧縮機構（40a）を備えている。低段側圧縮機構（40a）には、上流端が低段側シリンダ室（42a）に開口して低段側シリンダ室（42a）から冷媒の一部を排出させて低段側圧縮機構（40a）の吸入側へ戻すためのバイパス通路（66）が設けられている。バイパス通路（66）の上流端の断面は、回転軸（X）周りの周方向に細長い形状をしている。
