Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An air suspension apparatus comprising: a compressor configured to compress air; a tank configured to store the air; a first passage configured to supply the compressed air in the tank to a suction side of the compressor; a second passage 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; a first valve provided in the first passage; a second valve provided in the second passage; a third passage 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 third valve; and a fourth passage connecting the air drier and the air suspension, wherein a fourth valve is provided in the fourth passage, wherein the compressed air in the tank is supplied into the air suspension by closing the second valve and the third valve and opening the first valve, wherein the air drier can be regenerated via the compressed air in the air suspension by closing the first valve and the second valve and opening the third valve, and wherein a first orifice is provided between the air drier and the fourth valve and a second orifice is provided between the air drier and the second valve, and the first orifice has a larger orifice diameter than the second orifice. 2. The air suspension apparatus according to claim 1 , wherein air compressed by the compressor is supplied to the air suspension without intervention of the tank according to an instruction from a control unit. 3. The air suspension apparatus according to claim 2 , wherein the first valve and the second valve are two-way electromagnetic valves. 4. The air suspension apparatus according to claim 1 , wherein the first valve and the second valve are two-way electromagnetic valves.
