要求される用途においては不都合であつた。"Prior Art" In order to smoothly supply high viscosity substances such as fillers and adhesives to the required locations, it is necessary to apply higher pressure than in the case of low viscosity substances. Therefore, if we used a discharge gun with the same structure as a discharge gun for low-viscosity materials, that is, one that simply had one valve in the fluid flow path, a sudden pressure fluctuation would occur when the valve was opened, and the initial This results in an abnormally higher amount of discharge than the steady discharge amount. FIG. 4 shows this, where a represents the discharge pressure and b represents the discharge amount. Conventionally, no consideration was given to discharging in a steady state from the beginning, which was inconvenient in applications where a constant amount of discharge was required from the beginning.

Ru. On the other hand, when the first valve in the circulation passage is closed to stop discharging the high viscosity material, the second valve in the circulation passage is opened in conjunction with this, and the high viscosity material supplied from the high viscosity supply pump is opened. The viscous material is refluxed to the high viscosity material supply tank through the reflux path. As a result, the fluid pressure is always maintained constant, and sudden pressure fluctuations do not occur even immediately after opening the first valve of the flow path. Therefore, the discharge amount can be kept constant from the initial stage of discharge.
