  • Publication number: 20140352638
    Abstract: A camshaft adjusting device having a vane-type adjuster, which includes a stator which is rotatably drivable by a crankshaft; and a rotor which is rotatably supported in the stator and is connectable to a camshaft, a plurality of radially inwardly projecting projections, which divide an annular space between the stator and the rotor into multiple pressure chambers, being provided on the stator; and a plurality of radially outwardly projecting vanes, which divide the pressure chambers into oppositely acting working chambers, being provided on the rotor; a pressure medium being applicable to the working chambers to optionally adjust the rotor with respect to the stator via a central valve, the central valve being integrally connected to the rotor or to the stator or to a component which is rotatably fixedly connected to one of the two parts.

  • Publication number: 20110132303
    Abstract: 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.
