Abstract:
1. A device for ejecting a high-viscosity material in a constant amount, the device comprising: an ejection unit having an ejection port through which the high- viscosity material is ejected; a storage unit having a storage area in which the high-viscosity material is stored, a receiving port through which the high-viscosity material is supplied to the storage area, and a delivery port through which the high-viscosity material is delivered to the ejection unit; a high-pressure supply pump for supplying the high-viscosity material, which is filled in a container, to the storage unit under a first pressure; and a control unit, wherein a liquid feed unit is disposed in a flow path communicating the high-pressure supply pump and the storage unit with each other, the high-viscosity material is supplied to the storage unit by the liquid feed unit under a second pressure that is regulated to be lower than the first pressure, and the high-viscosity material is stored in the storage unit while a space regulated to be held at a third pressure is maintained in an upper portion of the storage area.
