Description
Claims (8)
- ピストン・シリンダユニットであって、ハウジング(2,12)内に摺動可能に配置された1つのピストン(3,14)と、ハウジング(2,12)とピストン(3,14)との間に設けられた少なくとも1つのシール手段(5)とが設けられており、該シール手段(5)がピストン(3)およびハウジング(2,12)と相俟って、液圧媒体で満たされた圧力室(13)を制限し、かつ以下のように形成されている、すなわちシール手段(5)が、少なくとも1つのシール面でもって、互いに軸方向で延在する2つの面の間のギャップ(17)を封止し、封止されたギャップ(17)が、有効な圧力面ADを規定するか、またはギャップ(17)がピストン(3)の圧力面と相俟って、有効な圧力面ADを規定するように形成されており、該有効な圧力面ADがピストン(3,14)の軸方向のストロークにわたって変化可能であり、ギャップ(17)の変化が、圧力領域における、可動な構成部分としてのピストン(3,14)の表面の形状変化、または定置の構成部分の、ピストン(3,14)の表面に半径方向で接触する内壁の形状変化により生じる形式のものにおいて、ピストン(3,14)の直径が、軸方向で見て曲線状に減径し、最小値の到達後、曲線状に増径して出発直径を再び取るか、またはハウジング(2,12)の、圧力室(13)の領域に、半径方向でシリンダ軸線(18)に向かって同様の曲線状の肉厚化部が設けられていることを特徴とするピストン・シリンダユニット。
- ピストン(3,14)の表面と、ピストン(3,14)を包囲する内壁との間の接触が、圧力領域で、軸方向および半径方向で運動可能な構成部分を介して形成され、該構成部分が両表面を互いに封止する、請求項1記載のピストン・シリンダユニット。
- シール(5)がリップ形シールとして形成されており、その動的なシールリップ(5b)でもって、シリンダ軸線(18)に対する間隔が変化する表面に当て付けられている、請求項1記載のピストン・シリンダユニット。
- 前記曲線状の肉厚化部がハウジング(2,12)の内壁により形成される、請求項1記載のピストン・シリンダユニット。
- 圧力室(13)の領域に、スリーブ(11a)が設けられており、該スリーブ(11a)の内壁が、シリンダ軸線(18)の方向で見て曲線状の、半径方向の肉厚化部を有している、請求項1記載のピストン・シリンダユニット。
- 圧力室(13)内に達する、軸方向で見て曲線状の肉厚化部が、マスターシリンダ(1)またはスレーブシリンダ(7)内に設けられている、請求項1記載のピストン・シリンダユニット。
- 圧力領域で、軸方向で見て曲線状に減径するピストン(3,14)が、マスターシリンダ(1)および/またはスレーブシリンダ(7)内に配置されている、請求項1記載のピストン・シリンダユニット。
- マスターシリンダ(1)およびスレーブシリンダ(7)が液圧的に互いに接続されており、クラッチ操作システムの部分である、請求項1記載のピストン・シリンダユニット。
