  • Air-suspension system
    Patent number: 5931451
    Abstract: An air-suspension system having a canister formed such that the inner diameter of an insert portion thereof is smaller than that of a tube mounting portion thereof to form a pressure-receiving portion between the insert and tube mounting portions. In addition, an air piston is formed such that the inner diameter of an insert portion thereof is smaller than that of a tube mounting portion thereof to form a pressure-receiving portion between the insert and tube mounting portions. When the pressure in an air chamber increases, the pressure-receiving portions receive the increased pressure to thereby strongly press the canister against a canister cap and the air piston against an air piston guide.
