Abstract
【解決手段】 気体吸入通路3から吸入した気体を圧縮し気体吐出通路から吐出する圧縮機構5と、気体吸入通路3での気体の逆流を防止する逆止弁7とを備えた気体圧縮機1であって、逆止弁7は、一側の端部が気体吸入通路3に開口し、他側の端部が気体溜まり9となる収容孔11と、収容孔11に移動自在に収容された弁体13と、収容孔11の前記開口側に設けられ、弁体13が押圧されると気体吸入通路3を閉止する弁座15と、弁体13を弁座15側に付勢する付勢手段17とを有し、収容孔11の壁部に、気体溜まり9と気体吸入通路3とを連通する気体抜き溝19を設けた。
【選択図】 図1
Description
図1〜図4によってベーン形圧縮機1(気体圧縮機)の説明をする。図1はベーン形圧縮機1の縦断面図、図2と図3と図4はそれぞれベーン形圧縮機1の要部を拡大した断面図である。また、図1の右方はベーン形圧縮機1の前方である。
一側の端部が気体吸入通路3に開口し、他側の端部が気体溜まり9となるスリーブ11(収容孔)と、
スリーブ11に移動自在に収容されたコア13(弁体)と、
スリーブ11の開口側に設けられ、コア13が押圧されると気体吸入通路3を閉止するストッパ15(弁座)と、
コア13をストッパ15側に付勢するコイルスプリング17(付勢手段)とを有している。
カム面の内側で回転するロータ21と、ロータ21に形成されたベーン溝と、ロータ21の回転に伴ってカム面と接触しながらベーン溝を進退するベーン23と、ベーン23とカム面との間に形成され、ロータ21の回転に伴って容積が変化する複数の圧縮室とを備え、ロータ21が回転すると、圧縮室の容積変化によって、気体吸入通路3から吸入した冷媒を圧縮し気体吐出通路から吐出する。
なお、本発明は上述した実施形態のみに限定解釈されるものではなく、本発明の技術的な範囲内で様々な変更が可能である。
