PURPOSE:When the detector detects sludge, the fuel pipe is automatically connected to the discharge pipe and simultaneously the by-pass valve is opened, thus, enabling automatic discharge of sludge formed, when fish oil is used as a fuel. CONSTITUTION:When Sludge is formed in the fuel pipe, the linear spring 12 is deformed by the pressure of the sludge and the permanent magnet 13 comes into contact with the lead switch 14 to shut it turn the transfer valve 8 to the discharge pipe 7 to discharge the sludge and simultaneously, the by-pass valve 10 is opened. The fuel oil is, as its reverse flow is inhibited by the valve 9, continuously fed through the by-pass 11. After the sludge is excluded, the linear spring 12 is restored and the transfer valve 8 and the by-pass valve 10 come back to the normal state.
