Abstract

A shaft-rotated throttle disk for use in the intake pipe of an internal combustion engine. The shaft is solid and the disk comprises a body (2) of material around it. The throttle disk offers little resistance to the flowing mixture and allows precise adjustment and regulation of the internal combustion engine upon closing. A seal (4) on the outside of the disk material extends on both sides as far as the shaft (1). The seal can be fully engaged with the intake pipe (3) by rotating the shaft.
