ABSTRACT:
In an apparatus for quantitatively supplying melted solder, a first chamber storing the melted solder is provided with a vessel of the apparatus. A second chamber communicates with the first chamber through a first communicating hole, and communicates with a third chamber through a second communicating hole. A nozzle for supplying the melted solder is disposed at the third chamber. A valve for opening and closing the first communicating hole is disposed therein. A piston is disposed in the second communicating hole. The melted solder stored in the first chamber is moved to the second chamber when the valve is opened. Subsequently, the valve is closed, and the piston which was disposed so as not to move the melted solder from the second chamber to the third chamber, is moved toward the second chamber, thus allowing the melted solder to move from the second chamber to the third chamber. When the piston is moved back toward the third chamber, the melted solder is supplied from the nozzle. Therefore, the melted solder is quantitatively supplied regardless of the amount remaining in the vessel.
