Abstract
A switching-type intake pipe for internal combustion engines comprises an intake duct with a shorting aperture. The shorting aperture can be closed and opened by a switching flap. The switching flap is connected via a non-rigid connection with a flap lever. The connection between the flap lever and the switching flap is formed by a plate on the one side and a calotte on the other side. Thus, a tiltable connection, which is easy to manufacture and install, is produced between the switching flap and the flap lever.
