Abstract
Abstract An articulated exhaust gas recirculation supply tube for an automotive engine includes an inlet tube with a first end adapted for connection with a source of exhaust gas from an engine and a second end having telescoping joint portion. An outlet tube has a first end adapted for connection with an exhaust gas recirculation control and a second end having a telescoping joint portion. An articulated gas conducting joint is slidingly engaged with the telescoping joint portions of the inlet tube and the outlet tube. A gas sealing member extends about both the telescoping joint portions of the inlet and outlet tubes and the articulated gas conducting joint.
