Claims

[Scope of utility model registration request]

The vehicle height signal detected by the vehicle height detection sensor is selectively supplied to the air intake valve or exhaust valve using the controller, and when the vehicle height reaches the up range, the air intake valve is opened and compressed air is supplied from the air tank etc. to the air suspension. In a vehicle height adjustment device, the air suspension is supplied with air to the air suspension, and when the vehicle height is in the down range, an exhaust valve is opened to remove compressed air from the air suspension to maintain the vehicle height at a predetermined level. A pressure detection sensor is provided to detect the pressure inside the air chamber, and a pressure high/low signal detected by the pressure detection sensor is selectively supplied to an air supply valve or an exhaust valve by a controller, so that the pressure inside the air chamber is equal to or higher than a set value. A vehicle height adjustment device for a vehicle, characterized in that when the air pressure reaches a certain level, the air supply valve is closed preferentially and the exhaust valve is opened to maintain the pressure in the air chamber below a set value.
