Connector for exhaust gas recirculation tube

摘要

A connector for attaching an exhaust gas recirculation tube to an intake manifold of an internal combustion engine. A thermal isolator surrounds an end of the tube and includes a sleeve contacting the tube and merging with a cylindrical body portion which is spaced from the tube. An upset bead is formed in the body portion. The tube and thermal isolator are inserted into a flange surrounding an opening formed in the intake manifold. A retainer is inserted into the flange and rotated such that latching devices on the retainer engage hooks on the flange to prevent removal of the retainer from the flange. The retainer also has ribs for supporting the body portion of the thermal isolator. The retainer is sized to engage the bead of the thermal isolator to prevent removal of the thermal isolator and tube from the flange. The flange and thermal isolator are sealed against fluid leakage.
