Abstract

A throttle valve connection piece for an internal combustion engine is disclosed, the piece including a housing and a throughflow opening in which the valve is pivotably mounted around a pivot axis. The pivot axis extends in a perpendicular manner with respect to a longitudinal axis the opening. The valve is used to close the throughflow opening. When in a closed position, the valve is inclined at a defined setting angle in relation to the longitudinal axis. The radial peripheral edge of the valve rests against the inner wall of the throughflow opening and the throughflow opening has a cylindrical shape at least in the region where the valve comes to rest. The cylindrical region of rest in relation to the longitudinal axis of the throughflow opening forms a circular cylinder which is cut on both sides at a certain angle, the levels of the cut are inclined at a similar angle in relation to the longitudinal axis.
