Air management system for vehicle

An air management system for a vehicle having a body and plurality of wheels, the air management system comprising:

• a reservoir tank for storing compressed air and filling at least one air spring of the vehicle;
• and
• a compressed air supply unit for supplying the compressed air, comprising:
• a compressed air port to the reservoir tank and to the at least one air spring;
• a vent port to a venting environment;
• and
• a piloted exhaust valve connected to the compressed air port and configured to vent the at least one air spring through the vent port, the piloted exhaust valve having a piloted control port;
• wherein the reservoir tank is pneumatically connected to the piloted control port of the piloted exhaust valve, and is configured to provide a control pressure to the piloted control port to open the piloted exhaust valve during venting of the at least one air spring;
• the compressed air supply unit further comprises an exhaust valve connected to the piloted control port, and the reservoir tank is pneumatically connected to and selectively pressurizes the piloted control port of the piloted exhaust valve via the exhaust valve;
• the air management system further comprises a manifold block, which pneumatically connects the at least one air spring, the compressed air port and the reservoir tank;
• and the reservoir tank is pneumatically connected to a control port of the exhaust valve via the manifold block;
• the compressed air supply unit defines a non-boost inlet port, the manifold block defines a non-boost outlet port, and the reservoir tank is pneumatically connected to the control port of the exhaust valve via the non-boost outlet port and the non-boost inlet port.
