1. A droplet ejection device comprising a flow passage, a nozzle orifice formed in a wall of the flow passage, a circulation system for circulating a liquid through the flow passage, and an actuator system for generating a pressure wave in the liquid in the flow passage, wherein an obstruction member is arranged in the flow passage in a position opposite to the nozzle orifice and projecting towards the nozzle orifice and wherein the obstruction member extends transversely to the flow passage over the width of the flow passage. |
