Abstract

Ein Ventiltrieb für eine Brennkraftmaschine weist ein angetriebenes Nockenelement (1), ein vom Nockenbereich des sich drehenden Nockenelements gegen eine Schließfeder (15) öffenbares Ventil (13) und eine hydraulische Spielausgleichseinrichtung auf, die eine mit einem Rückschlagventil (16) versehene Zuleitung (17) und eine Ableitung (6) für ein Druckübertragungsmedium umfaßt. Der Ableitung (6) ist ein federbeaufschlagtes Sperrelement (8) zugeordnet, das über den Nockenbereich des Nockenelementes (1) in Schließstellung und über den Grundkreisbereich in Offenstellung gehalten ist. Im Grundkreisbereich des Nockenelementes (1) ist ein Freiraum (2) ausgebildet, in den das Sperrelement (8) oder ein ihm zugeordnetes Halteteil (19) eintreten kann.
