PURPOSE:In a keeling system for bus, to reduce air consumption by discharging air only through a bellows at the elevating port side of car. CONSTITUTION:It is formed with a cut valve 26 having an exhaust port provided in a branch air feed path 24B corresponding with a bellows 18' in front of the elevating port of an air suspension car 12 and a cut valve 28 provided in main air feed path 24. The outlets 26b and 28b of cut valves 26 and 28 are coupled respectively to the bellows 18' and main air feed path 24. When lowering the car height, switch 34 and solenoid valve 32 are closed to close the inlet/outlet of cut valves 26, 28 thus to evacuate the bellows 18' through the exhaust port 26c and the outlet 26b of cut valve 26 and to lower the car height at the entrance. Consequently only the bellows 18' is required to be fed with air when resetting the car height, resulting in prevension of air consumption. |
