Claims

[Scope of utility model registration request]

In a viscous liquid supply device that supplies a fixed quantity of viscous liquid sent from a pump by a fixed quantity supply means provided in the middle of a supply pipe, an air pipe communicating with an air supply source is connected to the tip of the supply pipe, and A switching valve is provided in the middle of the air pipe, and the switching valve is closed when the fixed quantity supply means supplies a fixed quantity of viscous liquid, and when the fixed quantity supply means stops supplying the viscous liquid, the switching valve is opened, and the switching valve is closed from the air supply source. A viscous liquid supply device, characterized in that the compressed air is force-fed to the tip of the supply pipe to prevent the viscous liquid on the downstream side of the quantitative supply means from flowing out from the tip of the supply pipe.
