  • Device for changing the timing of an internal-combustion engine
    Patent number: 7305948
    Abstract: A device (1) for changing the timing of an internal-combustion engine (2) is provided that has a camshaft adjuster (5), which is supported on a non-rotating bearing journal (6). A driving wheel (8) of the camshaft adjuster (5) is driven by a crank-shaft (3) via a first traction mechanism drive (7). The rotation of the driving wheel (8) is transferred via an actuator (10) to a driven part (9), which is arranged so that it can rotate relative to the driving wheel (8). Second and third traction mechanism drives (11, 12) create a drive connection between the driven part (9) and two camshafts (4, 4a).
    Type: Grant

  • Internal-combustion engine with a hydraulic device for rotation angle adjustment of a camshaft relative to a crankshaft
    Publication number: 20050034693
    Abstract: An internal-combustion engine with a hydraulic device (1) for rotation angle adjustment of a camshaft (2) relative to a crankshaft is provided and includes a rotor with an impeller form (7), which is rotationally fixed via a central fastener (6) to the camshaft, and a stator (4), which rotates synchronously with a drive wheel (3) driven by the crankshaft, wherein on both sides of the impeller blades of the rotor, there are pressure chambers, which are each limited by radial walls of the stator (4) and can be filled with and emptied of hydraulic fluid via a hydraulic system, wherein the hydraulic fluid is guided, on one hand, via an annular gap (13) between rotor (7) and the central fastener (6) and, on the other hand, through generally axial and radial channels into the pressure chambers.
