Abstract
A combustion air intake system for an internal combustion engine has an intake manifold which supplies intake air to the engine through pairs of differing length intake runners. A valve assembly is disposed between the intake runners and the engine and includes a molded composite housing having pairs of combustion air through passages which are in flow communication with associate pairs of intake manifold runners. An axially extending valve bore defines an axis through the valve housing and bisects the through passages. Molded integrally within the valve housing is a molded composite valve member having an axial valve shaft, disposed in the valve bore, and integral valve plates, disposed in predetermined through bores. The valve member is rotatable in the valve bore to open and close the valve plates for regulation of air flow through the predetermined through bores and associated intake runners.
