The invention relates to a spilled oil recovery technology for a ventilation tank of an aircraft fuel system, in particular to an improvement on a spilled oil recovery system for the ventilation tank of a large aircraft inverted dihedral wing fuel system. The spilled oil recovery system for the ventilation tank of the large aircraft inverted dihedral wing fuel system is designed to solve problems of the traditional spilled oil recovery system such ascomplicated structure, heavy weight, low reliability, poor economic efficiency. In the spilled oil recovery system for the ventilation tank of the large aircraft inverted dihedral wing fuel system, a scavenge oil ejector pump is arranged in the ventilation tank; and an electric oil supply pump in a main oil tank is used as a moving flow source of the scavenge oil ejector pump so that spilled oil in the ventilation tank is conveyed into the main oil tank; therefore, unavailable oil quantity of an aircraft can be reduced, the oil loss is avoided and the flight safety is assured; and moreover, the whole recovery system has the advantages of simple structure, light weight and high reliability.
