摘要： An apparatus for variable setting of control times of gas exchange valves of an internal combustion engine which has an outer and inner rotor rotatable relative to the former, with one component drive-connected to a crankshaft and the other drive-connected to a camshaft. The apparatus has at least one pressure space, which are each divided into two pressure chambers acting counter to one another. The apparatus has a plurality of pressure medium channels, via which pressure medium is fed to or led away from the pressure chambers. Additionally, the apparatus has a plurality of rotational-angle limitation devices assuming an unlocked and locked state. The locking states are set by the supply of pressure medium to or discharge of pressure medium from the respective rotational-angle limitation apparatus. Furthermore, a method for controlling an apparatus for variable setting of control times of gas exchange valves of an internal combustion engine is disclosed.

The device includes the following: a cavity formed inside a camshaft; a first displacement element arranged in the cavity, which element can be displaced between a first end position and a second end position, the first displacement element having a first pressure surface which at least partially delimits a first accumulator chamber together with the wall of the cavity; a first energy accumulator which interacts with the first displacement element, the first displacement element being displaceable against the force of the first energy accumulator from the first end position into the second end position under the effect of pressure applied to the first accumulator chamber; a locking mechanism by which the first displacement element can be locked in the second end position; a switching mechanism which can be actuated by an actuator, having a switch element that can be brought into at least two switching positions and interacts with the locking mechanism in such a manner that the locked state of the first displacement element is maintained in a first switching position and is reversed in a second switching position; a second displacement element arranged in the cavity, which element can be displaced between a first end position and a second end position, the second displacement element having a second pressure surface which at least partially delimits a second accumulator chamber together with the wall of the cavity; a second energy accumulator which interacts with the second displacement element, the second displacement element being displaceable against the force of the second energy accumulator from the first end position into the second end position under the effect of pressure applied to the second accumulator chamber; the first accumulator chamber and the second accumulator chamber communicating with each other and being connectible to a pressure source in a fluid-conducting manner.

摘要： A device (10) for variably adjusting control times of gas exchange valves (9a, 9b) of an internal combustion engine (1), including 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 working chambers (35, 36) of each pressure chamber (33) acts as an advance chamber and the other pressure chamber (35, 36) as a retarding chamber. At least two rotation angle limiting devices (42, 43) are provided, with each of the rotation angle limiting devices (42, 43) being able to assume an unlocked state and locked state. The locked state can be adjusted by supplying or withdrawing a pressure medium to and from the respective rotation angle limiting devices (42, 43).
