摘要： The examples provide a fluid ejection apparatus that includes a fluid slot; a passage, a drop generator and a fluid circulation pump. The passage has an inlet connected to the fluid slot and an outlet spaced from the inlet and connected to the fluid slot. The passage as a first portion extending in a first direction from the inlet and a second portion extending from the first portion to the outlet in a second direction, opposite to the first direction. A filter is within the fluid slot across the inlet.

摘要： A fluid ejection apparatus may include a drop generator to eject fluid droplets in a vertical direction and a fluid channel containing the drop generator. The fluid channel may include a vertical inlet through which fluid is to enter the fluid channel and a vertical outlet through which fluid not ejected by the drop generator is to be circulated out of the fluid channel.

摘要： In some examples, a fluid nozzle includes an aperture comprising a first lobe that is shaped as an ellipse, and a second lobe that has a non-circular shape and has a different size than a size of the first lobe. The fluid nozzle further includes protrusions between the first and second lobes extending inward and forming a throat between the first and second lobes.
