Air induction channel system for internal combustion engine, with sealing rings in edge sectors acting with recesses in plastic bodies

摘要

The air induction system enables the lengths of channels in the cover body to be varied. The cover body (19) has sealing rings (25) in those edge sectors (18) which act with recesses (17) in the plastic bodies (15, 16). The rings are laid in grooves (27) in the endfaces (26). Their radial surfaces (28) act in combination with the recesses.
