| 摘要 |
The present invention relates to an air suspension pneumatic circuit comprising an air spring, a compressed air reservoir, a first valve, a second valve and a first check valve. The air spring is moved upward and downward depending on the inflow and outflow of compressed air. The compressed air reservoir stores the compressed air supplied to the air spring. The first valve is connected to the air spring and allows the compressed air to be transferred from the compressed air reservoir to the air spring when the first valve is opened. The second valve is branched between the first valve and the compressed air reservoir to allow the compressed air to be transferred from the compressed air reservoir to the air spring. The first check valve supplies the compressed air to one of the air spring and the compressed air reservoir and is connected to a compressor connected between the first valve and the second valve and the part between the compressor and the first valve, thereby controlling the flow of the compressed air from the compressor in one direction. The air suspension pneumatic circuit controls an air suspension device by performing heat exchange between the air spring and the compressed air reservoir. |
