摘要： An electrical adjusting device for changing an angle of rotation of a camshaft (3) relative to a crankshaft of an internal-combustion engine is provided. The device includes an adjusting gear unit (1), which is formed as a triple-shaft gear unit, including an input part (4) that is fixed to the crankshaft, an output part (5) that is fixed to the camshaft, and an adjusting shaft (6), which is connected in a torsion-proof manner to an electric adjusting motor (2) having a permanent magnet rotor and a stator (8) fixed to the housing. A stationary gear ratio (i0), the value of which defines the adjusting gear unit (1) as a positive or negative gear unit and deter-mines whether a direction of adjustment of the camshaft (3, 65, 69) is into an advanced or retarded base position, is located between the input part (4) and the output part (5) when the adjusting shaft is at rest. Due to the configuration of the adjusting gear unit (1), stationary gear ratios are provided, through which an advanced and a retarded base position of the camshaft (3, 65, 69) can be reached exclusively through braking of the adjusting shaft (6) when the adjusting gear unit (1) is rotating, and the braking of the adjusting shaft (6) is carried out through short-circuit braking of the adjusting motor (2).

摘要： A locking mechanism for a device (1) to modify the control timing of cylinder valves of an internal combustion engine, in particular for a vane-cell positioning device. The device (1) consists of a drive wheel (2) driven by a crankshaft of the internal combustion engine, said drive wheel having a cavity (6), and an impeller (8) permanently connected to the camshaft (7) that has at least one vane (12). In the cavity (6) of the drive wheel (2), at least one working chamber (15) is formed by intermediate walls (14) and each of these chambers is divided by an associated vane (12) into two hydraulic pressure spaces (16, 17). When pressure is applied by means of a hydraulic pressure medium, the pressure spaces (16, 17) effect a pivoting motion of the impeller (8) with respect to the drive wheel (2), whereas when the pressure is not applied to one of the pressure spaces (16, 17) the impeller (8) and the drive wheel (2) are mechanically coupled together. The mechanical coupling between the impeller (8) and the drive wheel (2) of the device (1) is accomplished by at least one axially moving vane (12) of the impeller (8) which is designed both as a vane pivoting element and as a locking element.
