Liquid agent application apparatus

摘要

Problem to be solved: to provide a liquid medicine coating apparatus capable of smoothly supplying liquid to the pressure chamber from the inflow passage.Solution: the liquid medicine application apparatus 100 includes a pressure chamber plate 8, a diaphragm 7, and a pressurizing driving unit 2.The pressure chamber plate 8 has a pressure chamber 82 for storing a liquid material, an inflow passage 81 connected to the pressure chamber 82, and a nozzle 83 connected to the pressure chamber 82.The diaphragm 7 is disposed on the pressure chamber plate 8.The pressurizing drive unit 2 applies a pressing vibration to the diaphragm 7.The ratio of the flow resistance of the nozzle 83 to the flow path resistance of the inflow passage 81 is one or more.
