US 2019/0100070 A1 · AIR SUSPENSION APPARATUS

Abstract

Provided is a closed type air suspension apparatus requiring no complicated control and capable of simplifying the overall structure. The air suspension apparatus includes a tank storing air, a return valve returning compressed air in an air suspension to the tank, a discharge valve discharging compressed air in the tank to the outside through an intake-discharge port when the compressed air between the intake side of a compressor body and the tank reaches a first value or more, and an intake valve opening when the pressure of the air between the intake side of the compressor body and the tank is at a second value less than the first value, thereby allowing the atmosphere (air) to be taken in from the intake-discharge port. The compressor body of a compressor compresses air including the compressed air in the tank.

Dependent claims

An air suspension apparatus comprising:

a tank configured to store air;
a compressor configured to compress the air supplied from the tank;
an air suspension connected to a discharge side of the compressor;
a return valve configured to return compressed air in the air suspension to the tank;
a discharge valve which is a pressure setting type check valve configured to discharge the air in the tank to an outside when a pressure of the air between an intake side of the compressor and the tank becomes not less than a first value;
and
an intake valve which is a pressure setting type check valve configured to open to take in air from an atmosphere when the pressure of the air between the intake side of the compressor and the tank is at a second value less than the first value.
