Nakano Air Hub
The "world's first automatic air replacement device for bicycle tires." Energy from the spinning wheel sets up a rotary cam action, that feeds a pump inside the hub, which in turns keep your tyres at the correct air pressure. Without any over-inflation, due a special valve.

Well from the Manufacturer website "Translated by Excite"
Online computer Translated version https://www.excite.co.jp/world/englis...=JAEN&wb_dis=2
*Original Japanese FAQ https://www.nakano-iw.co.jp/qa/index.html
2-How much air enters?
[scroll down]
So 3 atmosphere is about 44 psi.
And I don't think the valve is adjustable.
EDIT: Well the pressure valve might be change after all but
Well they say to never touch the hexnut. If you don't want to mess up with the pressure.

A. Air keeps being filled to the tube until sending air when the wheel rotates, and becoming 3.0 atmospheric pressures that are the tire standard air pressures. Afterwards, when pressure in the tube becomes more than about 3.0 atmospheric pressures, the air sent from the hub is discharged from the relief valve.
And I don't think the valve is adjustable.
EDIT: Well the pressure valve might be change after all but
The relief pressure changes if six corner nut in the relief valve point is done in, the air short supply and entering too much do not occur, and never touch, please.
