Abstract: Disclosed are a method of regenerating a flow path 6 injector, which processes a damaged injector body and a control valve coupled to the injector body to regenerate a damaged flow path 6 injector so that the damaged flow path 6 injector can be reused, and the flow path 6 injector regenerated by the same. To this end, the present invention provides a method of regenerating a flow path 6 injector, which comprises: a settlement check step of measuring the settlement distance of a path opening and closing ball from an injector body to a fuel oil path; an injector body processing step of expanding the inner diameter of a space in which the path opening and closing ball is settled to the inner diameter of an expansion hole so that the expansion hole is extended by the settlement distance; and a pin installation step of installing a distance control pin protruding as much as the settlement distance on a surface of a control valve facing the expansion hole. According to the present invention, the injector body can be recycled by cutting an inner surface of the injector body, which is worn or damaged by the raising and lowering of the path opening and closing ball or by foreign substances contained in fuel. In addition, when the expansion hole of the injector body is subsided, the stroke for moving the path opening and closing ball is lengthened, and since a path through which the fuel passes only as much as the diameter of the path opening and closing ball is formed, the fuel path is eliminated and the pumping amount is reduced.
