Apparatus for the variable setting of the control times of gas exchange valves of an internal combustion engine
Abstract:
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.
