ABSTRACT:
A baffle assembly for an air control device that reduces the noise associated with operation of solenoid coils. The invention employs one or two solenoid coils mounted in a frame and attached to a fixed plate. An armature, located inside the solenoid coils, is connected on opposite ends to two movable plates which rest on top of the fixed plate. Energizing a solenoid coil moves the armature, which moves the movable plates relative to the fixed plate. Apertures in the plates are provided to control air flow through the plates. The assembly includes sound dampeners to impede the movable plates from making contact with the frame, thereby reducing the amount of noise associated with operation of the solenoid coils.
