Exhaust gas recirculation valve
Abstract:
An exhaust gas recirculation EGR valve is provided. The exhaust gas recirculation valve has a housing, a closure member, and an electrical actuator. The electrical actuator includes a first core, a magnetic member, a second core, and a bobbin assembly supporting a coil aligned along the longitudinal axis. The bobbin assembly is coupled to the closure member. The bobbin assembly, including the coil, is movable within a generally toroidal volume. A force balance closure assembly is coupled to the coil assembly. Methods of actuating an EGR valve and of assembling a bobbin assembly are also described.
