Abstract
An intake device (1) for an internal combustion engine including a main body (2) and cover element (3; 20) which are securely connected to one another. Main body (2) and cover element (3) form intake pipes (4, 5, 6, 7) of in intake manifold. The cover element (3; 20) includes a plurality of individual shells (14, 15, 16, 17; 24, 25, 26, 27), which are connected to one another. Each individual shell (14, 15, 16, 17; 24, 25, 26, 27) forms a wall section of a respective intake pipe (4, 5, 6, 7) of the intake device (1). A flexible connection element (22) is arranged between two successively adjacent individual shells (25, 26) to compensate for tolerances between the cover element (3) and the main body (2).
