Abstract

An intake module for an internal combustion engine. The intake module including at least two intake ducts which can be opened and closed by rotatable valves. The valves are connected to one another via a coupling mechanism and to a common actuating mechanism in the form of a servomotor. In order to compensate for tolerances between the valves and the actuating mechanism, the coupling mechanism includes at least one elastic portion, formed by a weakened material portion, which allows the intake valves to be closed and opened completely. The resilience of the coupling mechanism can be brought about by a change in cross-section or a material reduction. In one embodiment of the invention, the coupling mechanism includes multi-part articulated main rods which control the valves by resiliently mounted legs. In another embodiment, the coupling mechanism includes a main rod having branch rods emerging therefrom with a resilient region extending as a relatively thin cross-section of the branch rods over their entire length.
