(54) INTEGRATED AIR SUPPLY UNIT


(57) An integrated air supply unit comprises a compressor housing, a pressure control unit (PCU) body, and a desiccant housing extending between the compressor housing and the PCU body. The desiccant housing defines a desiccant cavity holding a desiccant container for removing moisture from air passing therethrough. A piston is slidably disposed within a piston bore of the compressor housing. The PCU body defines a plurality of fluid passages with solenoid valves selectively controlling airflow therethrough. The integrated air supply unit may also comprise: a manifold, a discharge control valve, a compressor supplying pressurized air in a first pressurized air passage, a dryer configured to remove moisture from the pressurized air in the first pressurized air passage and to supply dried pressurized air in a second pressurized air passage, a supply control valve to control airflow between the second pressurized air passage and the manifold, and a piloted exhaust valve.
