Claims

[Scope of utility model registration request]

A high-pressure air-filled airtight container 5 provided on the circumferential surface of the rim 3 of the wheel 1, a conduction pipe 24 and a valve housing 8 that communicate the container 5 and the air chamber 11 in the tire 2, respectively, and the above-described components of the conduction pipe 24. a valve operating rod body 9 having a valve body 10 attached to one end thereof which normally closes one end opening into the container 5;
It includes a pressure receiving head 12 attached to the other end of the rod 9 penetrating into the valve housing 8 and a spring 17 provided on the valve actuating rod 9, so that the inside of the tire air chamber 11 is maintained at a predetermined pressure. In the state in which the pressure is maintained, this air pressure presses the pressure receiving head 12 in one direction against the force of the spring 17, and therefore similarly presses the valve actuating rod 9 against the force of the spring 17. The valve body 10 at the end of the rod closes the opening of the conduit pipe, but when the pressure within the tire air pressure 11 drops below a predetermined pressure, the force of the spring 17 closes the valve body. The actuating rod 9 is pressed in the other direction to open the conduit opening and the high pressure air in the airtight container 5 enters the tire air chamber 11 and restores the predetermined pressure. Tire pressure steady adjustment device.
