VARIABLE CHARGE MOTION VALVE STRUCTURE WITH DIFFERENCE THICKNESS MOLDING OF INTAKE MANIFOLD FOR VEHICLE

摘要

The present invention relates to a variable valve structure of an intake manifold for a vehicle having a molding part having a different thickness, and more particularly to a variable valve structure of a vehicle intake manifold that includes a plurality of branch pipes connected to an intake port of each cylinder of a vehicle engine, A driving shaft member having a variable valve structure of an intake manifold for a vehicle and having one end connected to the driving portion; And a plurality of variable valve plate members spaced apart from the drive shaft member to open and close the branch pipe, and a molding portion seated on the valve seat portion to seal the branch pipe is provided on an outer periphery of the variable valve plate member The thickness of the molding portion of the variable valve plate member on the side farther from the driving portion is made thicker than the thickness of the molding portion of the variable valve plate member on the side nearer to the driving portion so that each of the branch pipes can be uniformly sealed, Prevent performance degradation, and greatly reduce engine noise.
