Abstract: Provided is an apparatus for ejecting viscous liquid aerosol, and more particularly, an apparatus for ejecting viscous liquid aerosol capable of dispensing a viscous liquid to a work with a fine line width by ejecting the viscous liquid in the form of aerosols. The apparatus for ejecting viscous liquid aerosol may be configured compactly by miniaturizing a device capable of aerosolizing and ejecting viscous liquid in the form of aerosols. In addition, since the apparatus for ejecting viscous liquid aerosol has a structure that is easy to miniaturize, it is easy to uniformly maintain the characteristics of aerosol.

Abstract: A piezo-pneumatic valve driving type dispensing pump having an improved dispensing speed and a simplified structure, and a method of dispensing a viscous liquid by using the pump. Accordingly, a viscous liquid may be easily dispensed by reciprocating a valve rod inserted into a reservoir storing the viscous liquid, by using an air pressure. In particular, the air pressure may be precisely controlled by opening or closing a flow passage allowing the air to enter or exit, by using a piezoelectric element-based piezoelectric valve. Thus, the valve rod may be operated precisely at a high speed so that an exact amount of the viscous liquid is dispensed at a high speed.
