Abstract (en)
[origin: US2011132303A1] A device for the variable adjustment of the timing of gas exchange valves of an internal combustion engine, which has a hydraulic phase shifting device, a camshaft and a pressurizing distributor. The phase shift device can come into drive linkage with a crankshaft and is rigidly connected to the camshaft. A phase position of the camshaft relative to the crankshaft can be variably adjusted by the phase shift device. The interior of the camshaft has a cavity that communicates with one or more camshaft bearings which are separate from a rotating pressurizing means conveyor. The pressurizing distributor is disposed in a receiving area of the camshaft. The camshaft has an opening in the area of the pressurizing means distributor which with the interior of the camshaft and the rotating pressurizing conveyor. A pressurizing path is designed inside the camshaft which communicates with the opening and the hydraulic phase shift device.
