Abstract: A droplet ejection device includes a pressure chamber; a nozzle orifice arranged in fluid connection with the pressure chamber; an actuator system for generating a pressure wave in a liquid present in the pressure chamber; and an obstruction member arranged in the pressure chamber in a position opposite to the nozzle orifice. The obstruction member comprises a first surface facing the nozzle orifice and rigidly coupled to a wall of the pressure chamber via a support. The support is arranged near the first surface of the obstruction member. The droplet ejection device according to the present invention may further comprise a structured nozzle inflow means which provides a gradual transition from the hollow shaped liquid passage to the nozzle orifice. The droplet ejection device prevents or at least mitigates air entrapment in dead volumes present in the interior of the droplet ejection device.

Abstract translation: 液滴喷射装置包括压力室; 布置成与所述压力室流体连接的喷嘴孔; 用于在存在于压力室中的液体中产生压力波的致动器系统; 以及阻塞构件，其布置在所述压力室中与所述喷嘴孔相对的位置。 阻塞构件包括面向喷嘴孔口的第一表面，并且经由支撑件刚性地联接到压力室的壁。 支撑件设置在阻塞构件的第一表面附近。 根据本发明的液滴喷射装置还可以包括结构化的喷嘴流入装置，其提供从中空形状的液体通道到喷嘴孔的逐渐过渡。 液滴喷射装置防止或至少减轻存在于液滴喷射装置内部的死体积中的空气滞留。
