Abstract

Eine Aufgabe dieser Erfindung ist, den Betrieb zu vergleichmäßigen und den Leistungsausgang einer Unterdruckverstärkervorrichtung für eine Hydraulikbremsvorrichtung der Hub unabhängigen Bauart zu stabilisieren, in der eine Bremsbetätigungskraft unter Verwenden eines Unterdrucks eines Motors verstärkt wird und der Hauptzylinder unter Verwenden der verstärkten Kraft betätigt wird. Ein luftdichtes Abdichten zwischen einem Antriebskolben und einem Ventilkolben, der relativ zu dem Antriebskolben axial beweglich ist, und zwischen einem Stößel, der mit einem Eingangsschaft und dem Ventilkolben gekoppelt ist, werden durch Rolldichtungen ausgeführt, um eine unpräzise Bewegung des Ventilkolben zu verhindern, die dazu neigt, aufzutreten, wenn eine derartige luftdichte Abdichtung unter Verwenden von Gleitdichtungen ausgeführt ist.
