A FLUID EJECTOR

摘要

A fluid ejecting device includes a substrate (110) having a first surface (111) and a second surface (112) located opposite the first surface. A nozzle plate (140) is formed over the first surface of the substrate. The nozzle plate has a nozzle (152) through which fluid is ejected. A drop forming mechanism (151) is situated at the periphery of the nozzle. A fluid chamber (113) is in fluid communication with the nozzle and has a first wall and a second wall with the first wall (116) and the second wall (117) being positioned at an angle relative to each other. A fluid delivery channel (115) is formed in the substrate and extends from the second surface of the substrate to the fluid chamber. The fluid delivery channel is in fluid communication with the fluid chamber. A source of fluid impedance (114) comprises a physical structure located between the nozzle and the fluid delivery channel.
