An internal combustion engine with an adjustable compression ratio has a switchover valve (10) for controlling hydraulic oil flow in chambers of an eccentric adjustment device. The switchover valve (10) has a switching element (12) and a sleeve-shaped connecting section (16) with a first bore (17) that connects to a first hydraulic line (18), a second bore (19) that connects to a second hydraulic line (20), and a venting bore (21) that connects to a vent (22). The switching element (12) can be displaced in the connecting section (16) between a first position (S1) where a groove in the switching element (12) connects the first hydraulic line (18) to the venting duct (22) or a second position (S2) where the groove (14) connects the second hydraulic line (20) to the venting duct (22). A pick-off element (30) extends through the connecting section (16) and interacts with the switching element (12).
