Abstract
PURPOSE:To prevent erroneous fuel pouring by promoting vaporization of volatile components in fuel when fuel enclosed in a closing chamber is agitated, raising the inner pressure of the chamber in response to the mixture ratio of the components, and determining fuel type based on its pressure value. CONSTITUTION:A hose is connected to a coupling 5 to feed fuel to a fuel pouring tube 6. In this case, a fuel pouring valve 11 is closed, an isolation valve 14 is opened, and fuel is fed into a closing chamber 15. The valve 14 is closed, an intermittent agitating motor 17 is driven to agitate fuel in the chamber 15 by an impeller 18. When a determination start signal (e) is input from an agitation motor controller 27, a fuel type discriminator 30 compares a pressure signal (j) from a sensor 16 with a comparison value signal (i) from a comparison value setter 29, opens the valve 11 when the value of the signal (j) exceeds an A value if a tank 1 is for gasoline, and informs through an error fuel type informing unit 23 when it does not exceed. It opens the valve 11 under the condition that the value of the signal (j) does not exceed a B value if the tank is for kerosine, and simultaneously opens the valve 14. In the case of erroneous fuel pouring informing, the valve 14 is opened, a drain valve 33 is opened to discharge and recover the fuel.

（イ）産業上の利用分野
本願は蒸気圧の異なる複数種の液体を扱う場所たとえば
ガソリンや軽油を貯蔵供給する給油所等において、貯蔵
タンクへの誤注油を防止する装置に関する。DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present application is used to prevent erroneous oil filling into storage tanks in places where multiple types of liquids with different vapor pressures are handled, such as filling stations that store and supply gasoline and light oil. Regarding equipment.
（ロ）従来技術とその問題点
給油所等では注油に際して作業者が倉入りに油種の確認
を行なっている。(B) Prior art and its problems At oil filling stations, workers check the type of oil in the warehouse when filling oil.
油種の異なる油を混入してしまうと多蓋の油が使用不能
となり、知らずに自動車へ給油するとエンジントラブル
を起こしてしまうからである。This is because if different types of oil are mixed, the oil in multiple caps becomes unusable, and if you refuel a car without knowing it, it can cause engine trouble.
