CAR HEIGHT ADJUSTMENT DEVICE FOR AIR SUSPENSION VEHICLE

摘要

PROBLEM TO BE SOLVED: To disuse an air hold magnet valve provided at an upstream of an auxiliary air tank, to prevent excessive filling of air in the air tank at the time of kneeling and to prevent an erroneous operation of a pressure switch caused by a strong exhaust flow at the time of kneeling. SOLUTION: A direction control valve (3) for preventing excessive filling air in the air tank at the time of kneeling (at the time of descending of car height) is provided on an air circuit 1 between a leveling valve 2 and an exhaust valve (4) and an auxiliary tank (6) is provided on the air circuit (7) between the direction control valve (3) and the exhaust valve (4). A pressure switch (9) is provided on an air circuit (10) between a by-path magnet valve (8) for returning the car height and an air spring (5). COPYRIGHT: (C)2003,JPO
