A connecting rod 10 having a crankpin bearing eye 11, a connecting-rod bearing eye 12, and an eccentric adjustment device 13 for the adjustment of an effective connecting rod length, the eccentric adjustment device 13 having eccentric rods 15, 16 which engage on an eccentric lever 14 of the eccentric adjustment device 13, each eccentric rod being assigned a piston 20, 21 which is guided in a hydraulic chamber 22, 23 of the connecting rod, it being possible for the hydraulic chambers in which the pistons are guided to be charged with hydraulic oil from first hydraulic lines (41, Fig. 3) which are integrated into the crankshaft and which lead to the crankpin bearing eye 11, via second hydraulic oil lines 24, 25 which lead away from the crankpin bearing eye, and check valves 26, 27 preventing a backflow of the hydraulic oil from the hydraulic chambers back into the second hydraulic lines, at least one filter element 36 preventing an ingress of contaminants into the hydraulic chambers 22, 23 from the crankshaft via the hydraulic oil. |
