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.

An apparatus for quantitatively supplying a viscous liquid comprising: a vessel for containing the viscous liquid, said vessel having first, second and third chambers and first and second communicating holes, said first and second chambers communicating with each other through said first communicating hole and said second and third chambers communicating with each other through said second communicating hole; a nozzle communicating with said third chamber for supplying quantitative amounts of the viscous liquid from said vessel; means for selectively opening and closing said first communicating hole, said opening and closing means being selectively movable to a closed position which closes said first communicating hole and prevents the flow of viscous liquid from said first chamber to said second chamber and to an open position which opens said first communicating hole to allow the flow of viscous liquid from said first chamber to said second chamber; and control means for restraining the flow of viscous liquid from said second chamber to said third chamber when said opening and closing means is in said open position, for supplying a predetermined amount of viscous liquid from said second chamber to said third chamber, when said opening and closing means is in said closed position, and for supplying a predetermined amount of viscous liquid from said third chamber through said nozzle.
