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. The invention relates to a gas exchange system for an internal combustion engine with a hydraulically actuable gas exchange valve (20) and a first fluid system (30), connected to the gas exchange valve (20), for a working medium for actuating the gas exchange valve (20). The gas exchange system further comprises a second fluid system (40) for a hydraulic medium, a main control valve (50) provided in the second fluid system (40) for actuating the gas exchange valve (20), and a media separator arranged between the main control valve (50) and the gas exchange valve (20) (70), which is connected on the one hand to the first fluid system (30) and on the other hand can be connected to the second fluid system (40).
