Patent ID: 7299774

Claim:
A valve control for actuation of at least one valve (6), of an internal combustion engine, in which the measure of the valve lift of the at least one valve (6) corresponds to superimposing two cam profiles (1, 2) moving in synchronization, one of these two cam profiles (1; 2) determines mainly the valve opening range and the other cam profile (2; 1) determines mainly the valve closing range, the two cam profiles (1, 2) are mutually phase-variable, the valve lift period and the opening period of the at least one valve (6) can be varied through the phase displacement, the two cam profiles (1; 2) determine the valve lift via an intermediate element (4) acting on a lift actuating element (5) of the valve (6), intermediate element (4), namely a first guide area (111) comes in contact with a first of the two cam profiles (1) in all rotational positions, whereas this is not the case with the second cam profile (2) with respect to the second guide area (222) at least in a partial area of the basic circular area of this second cam profile (2), constant contact of the first guide area (111) of the intermediate element (4) on the first cam profile (1) is given by a guide means, wherein the guide means is designed as a third cam profile (3) which rotates in synchronization with the first cam profile (1) and has a complementary shape in comparison with the first cam profile (1).
