Abstract

Es wird ein Gaswechselsystem für eine Brennkraftmaschine vorgeschlagen mit einem hydraulisch betätigbaren Gaswechselventil (20), und einem ersten, mit dem Gaswechselventil (20) verbundenen Fluidsystem (30) für ein Arbeitsmedium zur Betätigung des Gaswechselventils (20). Das Gaswechselsystem umfasst ferner ein zweites Fluidsystem (40) für ein Hydraulikmedium, ein im zweiten Fluidsystem (40) vorgesehenes Hauptsteuerventil (50) zum Ansteuern des Gaswechselventils (20), sowie einen zwischen dem Hauptsteuerventil (50) und dem Gaswechselventil (20) angeordneten Medientrenner (70), der einerseits mit dem ersten Fluidsystem (30) verbunden ist und andererseits mit dem zweiten Fluidsystem (40) verbindbar ist.
