Abstract
A valve type nozzle controls discharge of a liquid by opening and closing a discharge port by a valve element. The discharge port discharges the liquid, and the valve element moves by applying a predetermined voltage to a piezoelectric element. When the predetermined voltage is applied to the piezoelectric element, the piezoelectric element extends and the valve element moves in a direction where the moving mechanism opens the discharge port. This allows the liquid to be discharged. Further, when the application of the voltage to the piezoelectric element is released, the moving mechanism returns to an original shape by which the valve element closes the discharge port to prevent the discharge of the liquid.
