Abstract

Die Erfindung betrifft ein hydraulisches System, insbesondere für Kraftfahrzeuge, umfassend einen Geberzylinder mit einem Gehäuse, einem in diesem axial verschiebbar angeordneten Kolben, der einen mit einer Hydraulikflüssigkeit gefüllten Druckraum begrenzt und bei Betätigung des Geberzylinders mittels einer auf den Kolben wirkenden Kolbenstange axial verschoben wird und dadurch die Hydraulikflüssigkeit mit Druck beaufschlagt wird und zumindest einem zwischen Gehäuse und Kolben angeordneten Dichtmittel, weiter umfassend einen Nehmerzylinder und eine diese verbindende Druckmediumsleitung. Das Problem, ein hydraulisches System mit einem Geberzylinder bereitzustellen, das in allen Betriebszuständen ein sicheres Schnüffeln, d.h. also einen Druckausgleich zwischen Druckraum und Nachlauf- und Entlüftungssystem ermöglicht, wird erfindungsgemäss gelöst, indem das Dichtmittel an der dem Kolben zugewandten Seite über mindestens eine sich im Wesentlichen in axialer Richtung erstreckende Nut verfügt.
