Abstract
Embodiments of a fluid transfer device are disclosed.
Claims14
A fluid transfer device, comprising:
- a die having first and second opposed surfaces;
- at least one nozzle formed in the first opposed surface;
- and
- a fluid slot formed in the second opposed surface, the fluid slot having an inlet adjacent the second opposed surface through which fluid wicks into the fluid slot via capillarity, and a separate outlet through which fluid exits to the at least one nozzle;
- the second opposed surface being a continuous surface except where the at least one nozzle is formed.

A fluid transfer device, comprising:
- a die having first and second opposed surfaces;
- at least one nozzle formed in the first opposed surface;
- a fluid slot formed in the second opposed surface, the fluid slot having an inlet adjacent the second opposed surface through which fluid wicks into the fluid slot via capillarity, and a separate outlet through which fluid exits to the at least one nozzle;
- and
- a member having a second fluid slot defined therein, the member being operatively connected to the die such that at least a portion of the second fluid slot is substantially aligned with at least a portion of the fluid slot, wherein the second fluid slot expands a volume of the fluid slot.

A fluid transfer device. comprising:
- a die having first and second opposed surfaces;
- at least one nozzle formed in the first opposed surface;
- a fluid slot formed in the second opposed surface, the fluid slot having an inlet adjacent the second opposed surface through which fluid wicks into the fluid slot via capillarity, and a separate outlet through which fluid exits to the at least one nozzle;
- at least one other nozzle formed in the second opposed surface such that the at least one other nozzle and the at least one nozzle are fluidly separated;
- and
- at least one other fluid slot formed in the second opposed surface such that the fluid slot and the at least one other fluid slot are fluidly separated, the at least one other fluid slot having an inlet adjacent the second opposed surface through which fluid wicks into the at least one other fluid slot via capillarity, and a separate outlet through which fluid exits to the at least one other nozzle.
3 more elements
A method of making a fluid transfer device, comprising:
- defining a fluid slot in a die such that a fluid inlet of the fluid slot is adjacent one of two opposed surfaces of the die;
- defining at least one nozzle in an other of the two opposed surfaces of the die, the other of the two opposed surfaces being continuous except where the at least one nozzle is formed, whereby the at least one nozzle is fluidly connected to an outlet of the fluid slot;
- and
- configuring a fluid ejection device in the die such that the fluid ejection device is capable of ejecting fluid through the at least one nozzle.
