PURPOSE:To reduce the pressure loss due to a dryer by carrying out dehumidification through a dryer when atmosphere is sent into a compressor and filling a high pressure tank through the compressor by selecting valves, in a compressed-air storing device for an air suspension device for vehicle. CONSTITUTION:An atmosphere suction port B and a low pressure tank A are connected through the first three-way solenoid valve C with the suction port E1 of the compressor E of a compressed-air storing device which compresses and stores the dehumidified air for pneumatic driving device. Further, the low pressure tank A and a high pressure tank G are connected through the second three-way solenoid valve F with the discharge port E2 of the compressor E, and a dryer D is installed between the second three-way valve F and the low pressure tank A. Switching is performed from the connection state of the atmosphere suction port B, compressor E, dryer D and the low pressure tank A to the connection passage of the low pressure tank A, compressor E, and a high pressure tank G, by selecting the three-way valves C and F. Since, in this case, dehumidification is performed in the passing through the low pressure tank, the pressure loss due to the dryer D can be reduced. |
