Abstract (en)
[origin: US2011162603A1] A device for variably adjusting the control times of gas exchange valves of an internal combustion engine. The device has a driving element, an output element, at least one pressure chamber, at least one mechanism limiting the angle of rotation, and a pressure accumulator. A phase angle between the output and driving element is changed by delivering or discharging pressure medium to or from the pressure chambers. The mechanism limiting the angle of rotation has a receiving member and an engaging element to which a force is applied towards the receiving member (45). When locked, where the engaging element engages into the receiving member, the mechanism limiting the angle of rotation limits the phase angle of the output element relative to the driving element at least to an angular spread. The mechanism limiting the angle of rotation can be unlocked by applying pressure medium to the receiving member.
