Abstract
An air-drying apparatus for use with compressed air-operated systems such as, for example, a vehicle suspension system, includes a housing having an inlet portion, a drying material portion, and an outlet portion. An activation piston is disposed within the inlet portion and is influenced by an operating compressed air in an operating phase, and is movable under the influence of a regenerative compressed air to open an exhaust valve during a regenerative phase. A throttle bypass opening between the inlet portion and drying material portion allows a secondary regenerative compressed air to contact the activation piston, thereby achieving a standby phase. An inlet check valve having a deflectable sealing lip portion is also formed on the activation piston. A discharge valve is disposed in the outlet portion to control the flow of compressed air to and from the vehicle-operating systems.
