PURPOSE:To make a remained pressure valve in an air dryer dispensable, and attain miniaturization of the device, by providing a remained pressure valve for maintaining an elevatable device in a prescribed remained pressure condition on the cylinder head of a compressor, which supplies compressed air to the elevatable device such as an air suspension for regulating vehicle height. CONSTITUTION:In a vehicle height regulating device by controlling charge and discharge of compressed air from an air compressor 8 to the air chamber of an air suspension provided on every wheel, a discharge port (not shown in the figure) communicating to a discharge hole 16 to discharge compressed air and an exhaust port 18 are provided on the cylinder head 14 of the compressor 8. An air dryer 26 receiving desiccant is provided on the discharge port and an electromagnetic exhaust valve 25 is provided on the exhaust port 18. A remained pressure valve 28 is provided between the air dryer 26 and the exhaust valve 25 in the exhaust port 18, and at trouble of the exhaust valve 25 and the like, pressure in respective air chambers 4A can be maintained in the prescribed remained pressure condition by closing the valve with a spring 34 for setting remained pressure. |
