Abstract

An actuating arrangement connected with throttle valves of suction pipes of an internal combustion engine which are to be actuated synchronously. The throttle valves include bearing shafts and cooperate by way of levers with a linkage of the actuating arrangement. For the compensation of tolerances of the actuating arrangement, especially angular tolerances of the throttle valves, yielding members are provided between the linkage and the bearing shafts, and a device stresses the throttle valves into the closed end positions.
