The present invention relates to a length-adjustable connecting rod, to a device for setting a compression ratio and to an internal combustion engine. A length-adjustable connecting rod with a small connecting-rod eye and a large connecting-rod eye preferably has a switching device. The switching device is preferably designed to control the length of the connecting rod, in particular hydraulically. In addition, the connecting rod preferably has an adjustment device which is actuable, in particular mechanically, from outside the connecting rod, has a rotatably mounted adjustment unit and is designed to mechanically switch, in particular to actuate, the switching device by rotation of the adjustment unit. 本发明涉及一种长度可调的连杆、一种用于调节压缩比的设备和一种内燃机。具有小连杆孔和大连杆孔的长度可调的连杆优选具有切换装置。该切换装置优选设置用于特别是液压式地控制连杆的长度。此外，连杆优选具有可从连杆外部特别是机械式操作的调节装置，该调节装置具有可旋转地支承的调节单元并且设置用于通过使调节单元扭转来机械式切换、特别是操作切换装置。
