Patent ID: 7814893

Claim:
A system module for recirculating exhaust gases from an internal combustion engine to an intake manifold of the internal combustion engine, the system module comprising: a body including a passageway between an exhaust gas inlet and an exhaust gas outlet, an orifice constricting the flow of exhaust gases proximate the exhaust gas outlet, differential pressure sensor constructed and arranged to sense differential pressure across the orifice, a manifold absolute pressure sensor constructed and arranged to sense vacuum pressure associated with the exhaust gas outlet, a first hose coupled with the body and providing the differential pressure sensor with vacuum pressure on a first side of the orifice, a second hose coupled with the body and providing the manifold pressure sensor with said vacuum pressure, and an electric vacuum regulator (EVR) valve constructed and arranged to regulate vacuum pressure in the body, wherein the differential pressure sensor and the manifold absolute pressure sensor are both part of sensor structure that is in fluid communication with the EVR valve.
