Abstract

Es wird ein Bremskraftverstärker für Kraftfahrzeuge vorgeschlagen, dessen Steuerventil (12) unabhängig von einer einen Ventilkolben (9) verschiebenden Betätigungsstange (7) mittels eines Elektromagneten (20) betätigbar ist, der einen dritten Dichtsitz (24) betätigt, der eine Belüftung der Arbeitskammer (4) ermöglicht. Der dritte Dichtsitz (24) ist an einer mit dem Elektromagneten (20) zusammenwirkenden Hülse (32) ausgebildet, wobei ein gegenüber dem dritten Dichtsitz (24) verschiebbar angeordnetes Ringelement (36) vorgesehen ist, der unter Zwischenschaltung eines elastischen bzw. zusammendrückbaren Elementes (37) an der Hülse (32) abgestützt ist. Um das Geräuschverhalten des Bremskraftverstärkers zu verbessern wird erfindungsgemäß vorgesehen, dass das Ringelement (36) Mittel zur Führung eines bei einer Normalbremsung auftretenden Luftstromes L in Richtung Arbeitskammer (4) aufweist.
