Control device for a gas exchange valve in an internal combustion engine

A control device for gas exchange valves (3) of an internal combustion engine having a multi-membered transmission, comprising

• at least one driving element (1, 22),
• actuating elements (2, 23) each of which actuates one gas exchange valve (3),
• a transmission element (9) which is hinge-connected between the at least one driving element (1, 22) and an actuating element (2, 23) acting on one gas exchange valve (3) each,
• a curve joint (15) between the transmission elements (9) and an area of a housing (5) of the control device, in which a first bearing area which is provided on the transmission element (9) and a second bearing area which is provided in the housing area are adjustable with respect to one another during operation of the engine,
• the second bearing area of the curve joint (15) of the transmission element (9), said bearing area being supported on the housing (5), is designed as an adjustable curve path which influences the path of movement of the transmission element (9) while the first bearing area, which is provided on the transmission element (9) cannot exert any variable movement of the respective transmission element, the second bearing area of the curve joint (15) is formed by the radial inside surface of an arc shaped element (16),
• the link element (16) is supported so that it is displaceable in the peripheral direction in a complementary guide surface of the housing of the control device, with a circular cylindrical peripheral surface that is on the outside radially,
• wherein
• the housing (5) of the control device is provided with a circular cylindrical recess (4), the inside circumference of which at least the driving element (1, 22), a supporting bearing (14) for the actuating elements (2,23) and the link element (16) are supported in a radially defined position.
