摘要：
An air dryer system for a trailer braking assembly is modified to provide a purge flow when the park brakes are actuated. An air reservoir, either the main air tank (44) or a separate reservoir (50), is in operative communication with the trailer air dryer (14). A valve (20) disposed at a supply end of the trailer air dryer selectively vents a purge flow to atmosphere in response to a park brake application. A restricting orifice (52) limits the purge flow through the trailer air dryer to extend the purge time and maximize the removal of moisture from the air dryer.
