Patent ID: 7124721

Claim:
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.
