<p>PROBLEM TO BE SOLVED: To provide an air suspension device which quickly increases/decreases car height with a simple configuration without requiring a conventional high pressure tank and a low pressure tank.SOLUTION: A variable capacity pressure storage container 4 for storing pressure in a supply and discharge path 2 and each air chamber is communicatively connected to the supply and discharge path 2 for communicatively connecting a compressor 3 to the air chambers 11-14, the pressure storage capacity is changed by a drive device 5, changeover control of a supply and discharge on-off valve 7 and each of wheel on-off valves 61-64 is performed, and air spring devices A1-A4 are controlled. The variable capacity pressure storage container includes an inner cylinder 41 forming a first pressure storage chamber V1, an outer cylinder 42 forming a second pressure storage chamber V2, and a piston 43 sliding in the inner cylinder, forms an atmospheric pressure chamber V3 between the piston and the inner cylinder, and communicatively connects the first pressure storage chamber and the second pressure storage chamber via a rod 44.</p> |
