Integrated intake manifold / throttle valve body

摘要

The assembly consists of an inlet manifold (1) and a throttle valve (5) and incorporates a regulating module (2) for its through section in line with the manifold air feed port. The module comprises an annular housing for the valve flap, mounted on a spindle (5') connected to a control system situated outside the housing. The module is prevented from rotating relative to the manifold by having the outer ends of its spindle or bearings engaging with matching recesses in the end of a manifold feed attachment (10), and is sealed by a compression joint (12).
