Switching assembly for closing intake lines of an air intake device and intake device incorporating same

A switching assembly for closing air intake lines of an intake device for an internal combustion engine, said switching assembly comprising:

• a plurality of closure elements arranged in passages formed by frames for the closure elements, said closure elements being produced by molding in mold cavities defined at least partially by partial surfaces of the respective frames, and
• a support member for accommodating a plurality of said frames, each frame having a passage for the intake air, the frames being adjacently arranged in the support member, and the passages corresponding to the intake lines;
• wherein each closure element includes a bearing shaft which is formed in one piece therewith and which defines an individual rotational axis for the respective closure element.

An intake device for intake air of an internal combustion engine, said intake device comprising a collector chamber having an inlet opening;

• a plurality of intake lines which branch off from the collector chamber and lead to a plurality of outlets to a cylinder head of the engine;
• a switching assembly installed in the intake device for closing at least a portion of said intake lines, and an actuator for actuating said switching assembly;
• wherein said switching assembly comprises a frame in which passages for the intake air corresponding to the intake lines are adjacently arranged, and a plurality of closure elements arranged in at least a portion of said passages, said closure elements being produced by molding in mold cavities defined at least partially by surfaces of said frame, and each closure element including a bearing shaft which is formed in one piece therewith and which defines an individual rotational axis for the respective closure element.
