Abstract

PURPOSE:To reduce cost without requiring many solenoid valves while to reduce malfunction and to facilitate maintenences and the inspection by regulating the amount of air of an air spring through utilization of a levelling valve of air- spring suspension mechanism. CONSTITUTION:In order to adust the car height, the discharge port is coupled to an air tank 12 while an intake port 9 is coupled to the discharge port 13. Consequently, a normal-close solenoid valve 16 is coupled between the paths 41 and 42 while a normal-open solenoid valve 15 is coupled to the end of the path 42. The air tank 12 is filled with pressurized air through an air pressure pump 31. In order to bring the car height higher than the referential level, the valve 15 is closed while the valve 16 is opened to feed pressurized air in the tank 12 through the valves 14, 16 and paths 42, 38 to an air spring 11. While in order to lower the car height, the valve 14 is closed and the valve 16 is opened to push open the intake valve 20 by the pressurized air from said spring 11 which is discharged through the discharge port 13.
