Abstract

Die Erfindung betrifft eine längenverstellbare Pleuelstange (6.1) für einen Verbrennungsmotor (1), mit einem ersten Pleuelteil (18.1), einem zweiten Pleuelteil (19.1) und mindestens einer Zylinder-Kolben-Einheit (20.1), um das erste Pleuelteil (18.1) relativ zum zweiten Pleuelteil (19.1) zu verstellen. Die Zylinder-Kolben-Einheit (20.1) umfasst eine Zylinderbohrung (22.1), einen in der Zylinderbohrung (22.1) längs bewegbar angeordneten Verstellkolben (21.1) mit einer Kolbenstange (18.1), mindestens einen in der Zylinderbohrung (22.1) vorgesehenen ersten Druckraum (24.1) und eine zwischen der Außenwandung (39.1) des Verstellkolbens (21.1) und der Innenwandung (38.1) der Zylinderbohrung (22.1) angeordnete Dichtungseinrichtung (23.1). Die Kolbenstange (18.1) erstreckt sich durch eine Stangenbohrung (36.1), in der sich radial um die Kolbenstange (18.1) herum ein Ölabstreifer (34.1) erstreckt.The invention relates to a length-adjustable connecting rod (6.1) for an internal combustion engine (1), with a first connecting rod part (18.1), a second connecting rod part (19.1) and at least one cylinder-piston unit (20.1) relative to the first connecting rod part (18.1) to adjust the second connecting rod part (19.1). The cylinder-piston unit (20.1) comprises a cylinder bore (22.1), an adjusting piston (21.1) arranged longitudinally movably in the cylinder bore (22.1) with a piston rod (18.1), at least one first pressure chamber (24.1) provided in the cylinder bore (22.1) ) and between the outer wall (39.1) of the adjusting piston (21.1) and the inner wall (38.1) of the cylinder bore (22.1) arranged sealing means (23.1). The piston rod (18.1) extends through a rod bore (36.1) in which an oil scraper (34.1) extends radially around the piston rod (18.1).
