Claims

[Scope of Claim for Utility Model Registration] (1) Increasing the vehicle height by supplying pressurized air from an appropriate pressure source to the air chambers of each air suspension installed on each of the front left and right sides and the rear left and right sides of the vehicle. In the vehicle height adjustment device, which is configured to discharge pressure air from the air chamber of each air suspension to enable lowering of the vehicle height, the pressure air from the pressure air source is transferred to each air suspension. In addition to making it possible to supply air into the air chamber of the
The pipe line that allows pressurized air to be discharged from each of the air chambers includes a high-pressure pressure switch that makes it possible to detect that each of the air chambers is in a high-pressure state;
A vehicle height adjustment device characterized in that a low-pressure pressure switch is provided for detecting that each of the air chambers is in a low-pressure state. (2) Request for registration of a utility model in which a pressure switch for high pressure and a pressure switch for low pressure are connected via a pressure regulating throttle in a conduit between a pressure air source and a leveling valve located near the air suspension. The vehicle height adjustment device according to item 1. (3) Vehicle height adjustment according to claim 1, wherein a high pressure switch and a low pressure switch are respectively provided for the front air suspension and the rear air suspension. Device. (4) The vehicle height adjustment device according to claim 1, wherein the pressure air source is a compressor.
