Claims

[Scope of Claim for Utility Model Registration] (1) A lever that pivotally supports a lever that swings as the vehicle body frame moves up and down, and supplies air from an air tank to an air spring that moves up and down the vehicle frame according to the amount of air stored. It constitutes an air supply path and an air discharge path that discharges the air in the air spring,
It has a pair of valves that respectively close the air supply path and the air discharge path, and one valve closes the air supply path when the lever swings in one direction from a predetermined position and the swing angle of the lever is less than the set angle. The air supply path is opened slightly, and when the swing angle of the lever exceeds the set angle, the air supply path is opened greatly, and the other valve opens the air supply path when the lever swing angle exceeds the set angle. A leveling valve device characterized in that an air discharge passage is slightly opened when the angle of swing of the lever is less than a set angle, and the air discharge passage is largely opened when the swing angle of the lever exceeds the set angle. (2) Each of the above-mentioned valves is constituted by a shaft-like member, and this shaft-like member is provided with a small diameter part and a large diameter part, and when the swing angle of the lever is less than the set angle, the large diameter part controls the flow of each passage. The leveling valve according to claim 1 of the utility model registration, characterized in that the cross-sectional area of the passage is regulated, and when the swing angle of the lever exceeds a set angle, the cross-sectional area of the passage of each passage is regulated at the small diameter portion. Device.
