    • A fluid ejection apparatus. The fluid ejection apparatus includes a chamber, a manifold, an orifice, a first bubble generating element and a second bubble generating element. The chamber contains fluid. The manifold is connected to the chamber. The fluid flows into the chamber at a first direction through the manifold. The orifice is connected to the chamber. The first bubble generating element is disposed above the chamber and close to the orifice to generate a first bubble. The first bubble generating element is substantially parallel to the first direction. The second bubble generating element is disposed above the chamber and is substantially parallel to the first direction to generate a second bubble. The second bubble generating element is close to the orifice and opposite to the first bubble generating element. The fluid in the chamber is ejected via the orifice by the first and second bubbles.
    • 流体喷射装置。 流体喷射装置包括腔室,歧管,孔口,第一气泡产生元件和第二气泡产生元件。 该腔室含有流体。 歧管连接到腔室。 流体通过歧管在第一方向流入腔室。 孔口连接到腔室。 第一气泡产生元件设置在室上方并靠近孔口以产生第一气泡。 第一气泡发生元件基本上平行于第一方向。 第二气泡生成元件设置在室上方并且基本上平行于第一方向以产生第二气泡。 第二气泡发生元件靠近孔口并与第一气泡发生元件相对。 腔中的流体经由孔口被第一和第二气泡排出。
