Vehicle air suspension circuit with a changeover means and a low pressure reservoir that surrounds a high pressure reservoir

摘要

A vehicle air suspension circuit having air suspensions for wheels and an air supply device which increases pressure of air taken from an air intake port and supplies the air to the air suspension. Moreover, this vehicle air suspension circuit is made up of a tank which receives the air discharged from the air suspension and is kept at the pressure higher than the atmospheric air pressure and a changeover valve which is provided to the air intake port of the air supply device and selects atmospheric air or the air in the tank as the intake air.
