Patent ID: 7137368

Claim:
A device for the variable actuation of the gas exchange valves in internal combustion piston engines, comprising: a housing (G), a shaft (W) seated in the housing (G) in a pivotable manner, the movement of which comes from a crankshaft, an output member (A), which is guided in the housing (G) and transmits the movement to the gas exchange valve (V) and an intermediate member (Z), which is connected with the shaft (W) and with the housing (G) via exactly one curved joint (zw, zg) and with the output member (A) via an additional joint (za), whereby a cam in the curved joint (zg) between the intermediate member (Z) and the housing (G) has a locking section and a controlling section, the position of the controlling section being set to the shaft (W) for the modification of the valve cam, the joint (za) between the intermediate member (Z) and the output member (A) being a curved joint such that the intermediate member (Z) may undergo rocking motion relative to the output member (A).
