Next, the operation of this embodiment will be explained. When it is necessary to raise the vehicle height, the push button 19 of the pressure increase valve 15 is pressed after the main switch 24 is closed.
Then, the valve body 18 is opened and the conduit 9 is opened, and at the same time the switch 23 is closed and the air pump 12 is activated, so that the pressurized air discharged from the valve body is supplied to the conduit 9, the pressure equalizer 6, and the conduits 5, 5'. The air is supplied into the cylinders 3 and 3' through the air cylinders 3 and 3', and the vehicle height increases due to the extension of the suspension system Sr. When the push button 19 is released when the desired vehicle height is obtained, the valve body 18 returns to the closed position due to the elastic force of the spring 17, cutting off the conduit 9, and the switch 23 opens to release the air. The operation of the pump 12 is stopped.

Conversely, if it is necessary to lower the vehicle height, the push button 34 of the pressure reducing valve 29 is pressed. Then, the valve body 33 is opened and the leak pipe 28 is opened, so that the pressurized air in the air cylinders 3, 3' is discharged into the atmosphere through the leak pipe 28, and the discharge speed is regulated by the orifice 30. The suspension system Sr gradually contracts to accurately lower the vehicle height. Then, when the desired vehicle height is obtained, if the push button 34 is released, the valve body 33 is activated by the spring 3.
Due to the elastic force of 2, the valve returns to the closed position and the leak pipe 2
8 is cut off, so air discharge stops.
