Abstract

ピストン圧縮機（１０）の回転シャフト（２２）の後部は、ロータリバルブ（３５）として形成される。ロータリバルブ（３５）は、吸入圧領域（１４ｂ）を複数の吸入通路（３３）に順次連通させる。その結果、吸入圧領域（１４ｂ）から、各々のリヤ圧縮室（２９ａ）に冷媒が導入される。ロータリバルブ（３５）は吸入切欠（４０）を有する。吸入切欠（４０）は吸入圧領域（１４ｂ）に常時連通する。吸入切欠（４０）は、吸入圧領域（１４ｂ）を各々の吸入通路（３３）に順次連通させる。吸入切欠（４０）は、回転シャフト（２２）の後部を、回転シャフト（２２）のリヤ端面（２２ｂ）から、吸入通路入口（３３ａ）全体に対向する位置まで切削することによって形成される。
