Abstract

Das Steuersystem zur Betätigung zweier mit einem Verstellelement zusammenwirkenden Stellkolben (14 und 15) für eine Vorrichtung zur Veränderung des Verdichtungsverhältnisses einer Zylindereinheit einer Hubkolbenbrennkraftmaschine. Das Verstellelement ist in einem Pleuelauge eines Pleuels angeordnet und ist in zwei unterschiedliche Positionen verstellbar, in welchen sich die in Stützzylindern (19 und 20) geführten Stellkolben (14 und 15) in einer eingefahrenen oder ausgefahrenen Stellung befinden. Dabei sind die zugehörigen Druckräume (21 und 22) mit einer Umschalteinrichtung verbunden, so dass über diese wahlweise eine der beiden Ölleitungen (24, 25) druckentlastbar ist. Die Umschalteinrichtung weist ein beide Stellkolben (14 und 15) steuerndes, zwei Schaltstellungen aufweisendes Wegeventil (29) auf und dass ein Steuerschieber des Wegeventils (29) über eine vom Pleuellager (23) ausgehende Fluidleitung (26) ausschließlich durch zumindest zwei unterschiedliche Steuerdrücke im Zusammenwirken mit einer Rückstellfeder (37) in seine beiden Schaltstellungen verschoben und in diesen gehalten wird.
