摘要

Inlet channel device for feeding a gas to the combustion chamber of an internal combustion engine comprises a swirl channel section (2) upstream of a valve seat region (1) and a feed channel arranged upstream of the swirl channel section. An adjusting device (4) defining the through opening (6) is provided in the feed channel. The position of the through opening relative to the swirl channel section can be adjusted. Preferred Features: The through opening forms a choke cross-section. The through opening is arranged eccentrically to a swirl channel blower stream section (3) which curves and tapers in a region between the choke cross-section and the swirl channel section toward the swirl channel section.
