Description
図1は、実施例のロータリ圧縮機を示す縦断面図である。図2は、実施例のロータリ圧縮機の圧縮部を示す分解斜視図である。図3は、実施例のロータリ圧縮機の圧縮部を上方から見た横断面図である。
次に、実施例のロータリ圧縮機1の特徴的な構成について説明する。図4は、実施例のロータリ圧縮機1の中間仕切板140を示す平面図であり、図5は、実施例のロータリ圧縮機1の中間仕切板140の凹部を説明するための部分斜視図である。
D≧0.1×L ・・・式1
を満たす。
ロータリ圧縮機1では、上シリンダ121T内及び下シリンダ121S内で上ピストン125T及び下ピストン125Sによって冷媒を圧縮するときに、回転軸15が軸方向に対して微小量だけ撓む。図6Aに示すように、回転軸15の撓みに伴って上ピストン125T及び下ピストン125Sが回転軸15と直交する方向に対して傾く。上ピストン125T及び下ピストン125Sが傾くことに伴って、ロータリ圧縮機1の上下方向(回転軸15の軸方向)における上ベーン127Tと上ベーン溝128Tとのクリアランス分、下ベーン127Sと下ベーン溝128Sとのクリアランス分だけ、図6Bに示すように、上ベーン127T及び下ベーン127Sが摺動方向に対して傾く。このため、上ベーン127Tの先端と上ピストン125Tの外周面との接触状態、及び下ベーン127Sの先端と下ピストン125Sの外周面との接触状態が変化し、上ベーン溝128T及び下ベーン128S内に拘束された状態で摺動する上ベーン127T及び下ベーン127Sの先端が上ピストン125T及び下ピストン125Sの外周面に片当たり状態になるおそれがある。
上述のように実施例のロータリ圧縮機1における中間仕切板140の外周部には、上ベーン127T及び下ベーン127Sが摺動する位置に凹部141が設けられ、上ピストン125T及び下ピストン125Sの下死点において、上ベーン127T及び下ベーン127Sの摺動方向における全長の80%以上が、上シリンダ121T内及び下シリンダ121S内にそれぞれ収容される。凹部141の深さをD、上ベーン127T及び下ベーン127Sの全長をLとしたとき、D≧0.1×L・・・式1を満たす。これにより、上ベーン127Tと上ピストン125Tとの片当たり、下ベーン127Sと下ピストン125Sとの片当たりの発生を抑え、上ベーン127T、下ベーン127S及び上ピストン125T、下ピストン125Sの摩耗や破損を抑えることができる。したがって、上ベーン127T及び下ベーン127Sの動作信頼性を高めることができる。
