Device for variable stroke control of valve, particularly gas exchange valve of internal combustion engine, has rotatably supported, drivable shaft, which carries work cam for valve actuation

摘要

The device has a rotatably supported, drivable shaft, which carries a work cam (13) for the valve actuation. The work cam sits freely rotatable on the shaft and transferable in oscillation by an eccentric arrangement. Two eccentrics are arranged on the shaft on both sides of the work cam rotatably incorporated in bearing housings. A coupling pin (20) is pivotably fixed on the bearing housings and coupled with the work cam over a pin-slot connection.
