EXHAUST GAS RECIRCULATION VALVE ASSEMBLY

A valve assembly (l0) for controlling recirculation of exhaust gases has three solenoid-operated valve members (32) that meter flow of exhaust gases through calibrated outlets (20a) from an exhaust gas chamber (l8). Each valve member (32) has a valve stem (30) extending to a respective solenoid arma...

Summary:A valve assembly (l0) for controlling recirculation of exhaust gases has three solenoid-operated valve members (32) that meter flow of exhaust gases through calibrated outlets (20a) from an exhaust gas chamber (l8). Each valve member (32) has a valve stem (30) extending to a respective solenoid armature (28), and each valve stem (30) is surrounded by a pair of spring-biased seals (34,36) that seal openings (44,50) around the valve stem (30) into a respective solenoid coil (24) and the chamber (l8). In this assembly (l0), each armature-valve member-seal (28,32,34,36) floats laterally to compensate for potential misalignment between the respective solenoid coil (24) and the respective outlet (20a).
