ABSTRACT:
A device (1) for simultaneous actuation of at least two gas exchange valves (2) of an internal combustion engine comprising a bridge-type cam follower (3) arranged in driving relationship between a camshaft and the gas exchange valves (2) and serving to directly transmit a stroke motion caused by a control cam (4) of the camshaft to the gas exchange valves (2), said cam follower (3) being guided by guiding means (18,19) for vertical displacement in a cylinder head and comprising a cam contacting element (31) on which the control cam (4) runs, characterized in that the cam contacting element (31) in the cam follower (3) is displaceable relative to the cam follower (3) so that the cam follower (3) can be uncoupled from a stroke-transmitting motion of the control cam (4).
