- 冷媒を圧縮する圧縮部と、コイルを有するステータを備え圧縮部を駆動する電動機と、圧縮部及び電動機が内部に収納されるハウジングとを備え、圧縮部において圧縮した冷媒によって電動機を冷却し、電動機を冷却した冷媒をハウジング外に吐出するようにした圧縮機において、
前記ハウジング内の空間をハウジングの内側面に対向して内外に仕切る仕切部材を設けるとともに、
前記仕切部材の内側には前記圧縮部から電動機側に流入する冷媒を前記ステータの軸方向一端部から他端部に向けて案内する空間を有し、該仕切部材の外側にはステータの軸方向他端部から流出した冷媒をハウジングの内面に沿って冷媒吐出管側の空間に向けて案内する連通路を有し、
前記仕切部材の内側の前記空間には、上流側の流速に対して下流側の流速が速くなるように流通させるための冷媒流通手段を備えた
ことを特徴とする圧縮機。 - 前記冷媒流通手段を、圧縮部と電動機との間の冷媒流路を閉鎖する流路閉鎖板と、流路閉鎖板に設けられた冷媒噴出孔とから構成した
ことを特徴とする請求項1記載の圧縮機。 - 前記流路閉鎖板を、ステータの中心軸方向一端と間隔をおいて設け、
冷媒噴出孔を、互いにステータの周方向に間隔をおいて複数設けた
ことを特徴とする請求項2記載の圧縮機。 - 前記冷媒として二酸化炭素を用いた
ことを特徴とする請求項1乃至3の何れか一項に記載の圧縮機。
