CONSTITUTION: A safety type air suspension device comprises an air spring(10), a compressor(20), a solenoid valve block(30), an electronic control unit(ECU)(40), and a relief valve(50). The solenoid valve block controls the supplying of compressed air to the air spring according to the control of the electronic control unit. The electronic control unit is installed to control the compressor and the solenoid valve block. The relief valve controls the pressure in a feeding line directly connected to the air spring lower than a critical level. |
