Abstract
An air suspension system includes an air suspension, a compressor, a dryer apparatus, and so forth. The dryer apparatus includes a dryer case, an inner cylinder, a first inlet port, a first outlet port, a first desiccant, an outer cylinder, a second inlet port, a second outlet port, a second other-end side filter, a second desiccant, and so forth. The first desiccant comprises a molecular sieve, for example, which exhibits high water adsorption performance at high temperature. On the other hand, the second desiccant comprises silica gel, for example, which exhibits high water adsorption performance at low temperature.
Claims7
A dryer apparatus comprising:
- a plurality of different types of desiccants filled therein to dry compressed air, wherein the plurality of different types of desiccants are provided being separated from each other, and
- wherein the plurality of different types of desiccants are provided in series with each other in a flow direction of compressed air,
- the dryer apparatus further comprising a dryer case, the dryer case including:
- a first inlet port through which compressed air flows in;
- a first drying cylinder filled with a first desiccant that dries compressed air flowing in from the first inlet port;
- a first outlet port through which compressed air flows out of the first drying cylinder;
- a second inlet port in which compressed air flowing out from the first outlet port flows;
- a second drying cylinder filled with a second desiccant that dries compressed air flowing in from the second inlet port;
- and
- a second outlet port through which compressed air flows out of the second drying cylinder;
- the first desiccant being higher than the second desiccant in water adsorption performance when compressed air is at high temperature.
