摘要:
A fluid ejector includes a nozzle layer, a body, an actuator and a membrane. The body includes a pumping chamber, a return channel, and a first passage fluidically connecting the pumping chamber to an entrance of the nozzle. A second passage fluidically connects the entrance of the nozzle to the return channel. The actuator is configured to cause fluid to flow out of the pumping chamber such that actuation of the actuator causes fluid to be ejected from the nozzle. The membrane is formed across and partially blocks at least one of the first passage, the second passage or the entrance of the nozzle. The membrane has at least one hole therethrough such that in operation of the fluid ejector fluid flows through the at least one hole in the membrane.
