发明名称 Device for variably adjusting the control times of gas exchange valves of an internal combustion engine
摘要 A device (10) for variably adjusting control times of gas exchange valves (9a, 9b) of an internal combustion engine (1) is provided, having an external rotor (22) and an internal rotor (23) that is arranged such that it can rotate in relation to the external rotor. One of the components is drivingly connected to the crankshaft (2) and the other component is drivingly connected to the camshaft (6, 7). At least one pressure chamber (33) is provided and each of the pressure chambers (33) is divided into two counter-working pressure chambers (35, 36). One of the pressure chambers (35, 36) of each pressure chamber (33) acts as an advance chamber and the other pressure chamber (35, 36) as a trailing chamber. At least two rotation angle limiting devices (42, 43) are provided, each of the rotation angle limiting devices (42, 43) being able to assume an unlocked state and locking state. The locking state can be adjusted by supplying or withdrawing a pressure medium to and from the respective rotation angle limiting devices (42, 43).
