An air suspension apparatus includes a compressor configured to compress air, a tank configured to store the air, a tank-side suction conduit configured to supply the compressed air in this tank to an intake side of the compressor, a tank conduit connecting a discharge side of the compressor and the tank, an air suspension connected to the discharge side of the compressor via an air drier, an intake electromagnetic valve provided in the tank-side suction conduit, a return electromagnetic valve provided in the tank conduit, and a discharge conduit provided so as to branch off from between the discharge side of the compressor and the air drier and configured to be connected to an atmosphere by opening a discharge electromagnetic valve.

Air suspension apparatus

Provided is a compressor capable of achieving a reduction in overall size and an improvement in vehicle mountability by using a linear motor. The compressorcomprises a linear motorhaving a reciprocating mover, a compression unithaving a pistonconnected to the moverat one end side of the linear motorso as to reciprocate and a cylinderslidably accommodating the pistonto form a compression chamberB, and an air dryerconnected to a cylinder headof the compression chamberB of the compression unitand filled therein with a desiccantC. The air dryeris disposed along the axis in the movement direction of the moverthe piston
