<p>A liquid discharge method and device that, on the basis of mechanically opening and closing the discharge opening in a discharge valve, improve the ability to cut off liquid upon stoppage of discharge without the danger of the filler being destroyed and that fully prevents leakage of liquid. The method of discharging liquid from a liquid storage vessel through a discharge valve at a constant rate, characterized by comprising the steps of controlling the pressure of the liquid being fed from the liquid storage vessel to the discharge valve, according to the liquid pressure in the region near the discharge opening in the discharge valve, and mechanically opening and closing the discharge opening; and the device for discharging liquid from a liquid storage vessel through a discharge valve at a constant rate, characterized in that the liquid storage vessel of this device is provided with a pressing means for pressing the stored liquid at a pressure depending on the viscosity thereof, and in that the discharge valve communicating with the liquid storage vessel has a construction such that its discharge opening is mechanically opened and closed. <IMAGE></p> |
