摘要

A variable geometry intake manifold (3) for an internal combustion engine (1); the intake manifold (3) presents: at least one intake pipe (9) which connects the intake manifold (3) to at least one cylinder (2) of the internal combustion engine (1); and a choking system (14) to vary the geometry of the intake manifold (3) and comprising at least one choke valve (15) provided with a choke body (17), which is arranged within the intake pipe (9) and is turnably mounted about an axis of rotation (19); the choke valve (15) integrates therein a pair of mechanical stoppers (23), which respectively determine the location of an active position and of a home position of the choke body (17).
