    • A fluid ejector includes a fluid ejection assembly, a housing, and an insert. The fluid ejection assembly includes one or more silicon bodies and a plurality of actuators. The one or more silicon bodies includes a silicon body having a plurality of fluid passages for fluid flow and a plurality of nozzles fluidically connected to the plurality of fluid passages. The plurality of actuators cause fluid in the plurality of fluid passages to be ejected from the plurality of nozzles. The housing assembly includes one or more plastic bodies, at least one plastic body attached to at least one silicon body to form a sealed volume on a side of the fluid ejection assembly opposite the nozzles. The insert is embedded in the at least one plastic body in proximity to the at least one silicon body, the insert having a coefficient of thermal expansion of less than 9 ppm/° C.
    • 流体喷射器包括流体喷射组件,壳体和插入件。 流体喷射组件包括一个或多个硅体和多个致动器。 一个或多个硅体包括具有多个用于流体流动的流体通道的硅体和与多个流体通道流体连接的多个喷嘴。 多个致动器使多个流体通道中的流体从多个喷嘴喷出。 壳体组件包括一个或多个塑料体,至少一个塑料体附接到至少一个硅体,以在流体喷射组件的与喷嘴相对的一侧上形成密封体积。 插入件嵌入在至少一个硅体附近的至少一个塑料体中,插入件的热膨胀系数小于9ppm /℃。
