Abstract

　ガスインジェクションサイクルによる能力向上を図るとともに、製造コスト上昇を防止することができるスクロール圧縮機および空気調和機を提供する。それぞれの端板（２３ａ，２５ａ）の一側面に渦巻き状の壁体（２３ｂ，２５ｂ）を立設させた固定スクロール（２３）および旋回スクロール（２５）が、互いに噛み合うことにより冷媒を圧縮する複数の圧縮室を形成するスクロール圧縮機であって、固定スクロール（２３）の端板（２３ａ）の一側面には段差部（４２）が設けられるとともに、旋回スクロール（２５）の壁体（２５ｂ）の上縁には、端板（２３ａ）の段差部（４２）に対応する段付部（４５）が設けられ、冷媒を圧縮中の複数の圧縮室に、外部から供給された冷媒を供給する供給部（１７ｐ）が設けられ、少なくとも複数の圧縮室が離間した段差部（４２）および段付部（４５）を含む間に、供給部（１７ｐ）から冷媒が供給されることを特徴とする。
