摘要： A system for the rotation of a camshaft relative to a crankshaft of an internal combustion engine, which includes a drive pulley connected to the crankshaft of the engine through a chain, belt, or sprocket drive, and includes an electric motor that transfers torque to the camshaft of the engine. The electric motor is flanged directly to one end of the and is a primary drive unit of the camshaft as well as a servomechanism to adjust and maintain a controlled camshaft angular shift, whereas the drive pulley is fastened to and moves about the other end of the camshaft within a defined range of rotation and is provided as a forced synchronization instrument for the electric motor within the range of rotation, as well as being a secondary drive unit of the camshaft. Further, the electric motor (7) is connected to an RPM controller (10) that synchronizes and modifies the RPM of the electric motor (7) relative to the RPM of the drive pulley (4).

摘要： The invention relates in particular to a camshaft setting mechanism according to the vane cell principle, which has a drive gear (1) joined with the crankshaft through a toothed belt or a control chain. The drive gear includes a hollow space (8), and an impeller (11) is installed in the hollow space (8). The impeller is fixedly connected to and rotates with the camshaft (14). The drive gear (1) has at least one working chamber (4) on the interior of its circumferential wall (2), and each vane (12) of the impeller (11) subdivides the working chambers (4) into two pressure areas (9, 10) in each case. To avoid leakage through the slits (13) between impeller (11) and the drive gear (1) at high oil temperatures, the impeller (11) is made of a material which has a higher thermal expansion coefficient than the material of the drive gear (1), and that the pressure areas (9, 10) in the hollow space (7) of the drive gear (1) are sealed off by thermal expansion of the impeller (11) when the motor is in operation.

摘要： A device for changing the control times of gas exchange valves of an internal combustion engine, including a drive wheel in driving connection with a crankshaft and a vane wheel connected to rotate with a camshaft. A plurality of hydraulic working spaces are formed within the device and are divided by the vanes of the vane wheel into respectively A and B pressure chambers. The vane wheel can be mechanically coupled to the drive wheel by a locking element, which is displaceable by a spring element into a locking position within a seat in one of the sidewalls of the drive wheel, and is hydraulically moved into an unlocked position in the vane wheel upon application of pressure to the pressure chambers. The locking element is a generally uniform cylindrical locking pin, and is arranged in an axial bore in the hub of the vane wheel. The longitudinal axis of the axial bore has a smallest possible distance from the longitudinal mid-axis of the device. The seat has a generally quadrilateral shaped contour that is larger by a play on all sides than the cross sectional area of the locking element, and includes a worm groove opening into it for supplying pressure medium.
