Abstract
An air dryer includes first and second flow paths. Each flow path includes a check valve that prevents fluid flow into the flow path and an exhaust valve having an open position that permits fluid flow out of the flow path and a shut position that prevents fluid flow out of the flow path. A diverter valve has a first position that provides fluid communication to the first flow path and a second position that provides fluid communication to the second flow path. An interlock operably connected to the diverter valve and the exhaust valves prevents positioning the diverter valve to the first position when the exhaust valve in the first flow path is in the open position and prevents positioning the diverter valve to the second position when the exhaust valve in the second flow path is in the open position.
