Abstract

Die Erfindung betrifft eine Hauptbremszylinderanordnung für eine Kraftfahrzeugbremsanlage umfassend: - ein Hauptbremszylindergehause (12) mit einer Ausnehmung (14), - wenigstens einen in der Ausnehmung verlagerbar und geführten Druckkolben (16, 18), - ein mit dem Hauptbremszylindergehause über einen Fluidkanal (44) gekoppeltes Flüssigkeitsreservoir, wobei der Druckkolben mit dem Hauptbremszylindergehause eine Druckkammer (56, 58) einschließt, die mit einem Fluidkreis der Kraftfahrzeugbremsanlage koppelbar ist und in Abhängigkeit von der Stellung des Druckkolbens mit dem Flüssigkeitsreservoir verbunden ist, und wobei zwischen der Außenumfangsfläche (60, 62) des Druckkolbens und der zylindrischen Ausnehmung eine den Druckkolben umschließende Dichtungsanordnung (46, 48) vorgesehen ist. Zur Verbesserung des Ansprechverhaltens ist vorgesehen, dass die Außenumfangsfläche (62) des Druckkolbens in einem Bereich, der in einer Ausgangsstellung des Druckkolbens die Dichtungsanordnung in axialer Richtung überspannt, mit einer Profilierung (64, 66) versehen ist, die eine Verbindung zwischen dem Flüssigkeitsreservoir und der Druckkammer vorsieht.
