ABSTRACT:
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.
