Abstract
An air dryer apparatus is provided for a vehicle air brake charging system. The air dryer apparatus comprises an air dryer governor assembly. The air dryer governor assembly includes a plastic sleeve having an external sleeve surface and an internal sleeve surface that defines a piston bore. The air dryer governor assembly also includes a piston disposed in the piston bore and slidable along the internal sleeve surface between a preset cut-out setting and a preset cut-in setting of the air dryer governor assembly. The air dryer governor assembly further includes one or more ribs disposed on the external sleeve surface to prevent deformation of the plastic sleeve when the piston slides along the internal sleeve surface between the preset cut-out and cut-in settings.
