ABSTRACT:
A valve assembly for controlling recirculation of exhaust gases has three solenoid operated valve members that meter flow of exhaust gases through calibrated outlets from an exhaust gas chamber. Each valve member has a valve stem extending to its solenoid armature, and each valve stem is surrounded by a pair of spring-biased seals that seal the openings around the valve stems into the solenoid coils and the chamber. In this assembly, each armature-valve member-seal floats laterally to compensate for potential misalignment between the solenoid coils and the outlets.
