Abstract: A dispensing pump, and more particularly, a valve impact type dispensing pump that may be used in a process of manufacturing an electronic product and may dispense an accurate amount of a liquid, such as a liquid synthetic resin, at high speed. The valve impact type dispensing pump can descend a valve rod at high speed and thus can dispense a liquid with high viscosity at high speed. The valve impact type dispensing pump can dispense an accurate amount of a liquid at high speed. Also, the valve impact type dispensing pump can dispense a liquid having high viscosity at high speed due to a fast descending speed of a valve rod.

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.
