Patent ID: 6907868

Claim:
A modular exhaust gas recirculation assembly comprising: a flow control body including: a manifold conduit including a recirculation opening, a first open end having a first cross-sectional shape and a second open end having a second cross-sectional shape; and an inlet conduit in fluid communication with the manifold conduit; a closing member movably mounted in the manifold conduit and having a boundary defining an operative surface, the boundary having a configuration different from at least one of the first cross-sectional shape and the second cross-sectional shape, the closing member further having a first position where the closing member closes the recirculation opening and blocks fluid communication between the inlet conduit and the manifold conduit and a second position where the closing member opens the recirculation opening and permits fluid communication between the inlet conduit and the manifold conduit and such that the operative surface creates a pressure differential across the recirculation opening so that fluid is drawn from the inlet conduit into the manifold conduit; and an actuator assembly coupled to the closing member and driving the closing member between the first position and the second position.
