    摘要： A rotational phase difference of a camshaft relative to a crankshaft in a variable valve timing mechanism is controlled by an operation of an oil control valve. That is, in the oil control valve, there is outputted an operational signal which is defined by adding a feedback correction amount corresponding to a difference between an actual value and a target value of the rotational phase difference, to a holding learning value as the operational signal for holding the rotational phase difference. The holding learning value is altered only by a specified value on condition that the operational signal for holding the rotational phase difference is assumed to change.

    摘要： The movable actuating lever is connected to a transmission lever, at one hand, and is guided by means of a pin within a guideway in the housing of the apparatus, on the other hand. The transmission lever serves at the same time for transmitting the actuating motion via further levers to the apparatus part to be actuated. Due to the position and the shape of the guiding groove and the lever, the course of motion of the actuating lever with respect to the fixed handle portion may be optimally adapted to technical and ergonomic requirements in order to achieve an effective force transmission having minimal frictional losses. Furthermore, no levers are in the way, and injuries are avoided.
