Document Type and Number:
Japanese Patent JP3899200
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a stop or supply and the occurrence or overflow by a method wherein even when a liquid level is abnormally raised, liquid fuel is caused to flow to the outside of a tank, and even when liquid fuel in a piping reversely flows in the tank due to a temperature difference in a season, the liquid level is not raised to a second abnormal liquid level, and liquid fuel is returned to a main tank.
SOLUTION: In a constant oil level apparatus, a first valve member 5 consisting of a motor-driven on-off valve is arranged on the inflow side of a tank 4. A first liquid level sensor 1 to detect a first upper limit constant liquid level 38a higher by one point or more than a normal liquid level 41 and a second liquid level sensor 2 to detect a second upper limit abnormal liquid level 43 higher than the first upper limit abnormal liquid level 38a and have a normally closed contact are independently arranged in the tank 4.
