Abstract
A fluid ejection device includes a fluid slot, a first fluid ejection chamber communicated with the fluid slot and including a first drop ejecting element, a second fluid ejection chamber including a second drop ejecting element, and a fluid circulation path including a first portion communicated with the fluid slot and the second fluid ejection chamber, and a second portion communicated with the first fluid ejection chamber and the second fluid ejection chamber, with the fluid circulation path including a fluid circulating element within the first portion.
Claims20
A fluid ejection device, comprising:
- a fluid slot;
- a first fluid ejection chamber communicated with the fluid slot and including a first drop ejecting element;
- a second fluid ejection chamber including a second drop ejecting element;
- and
- a fluid circulation path having a first end communicated with the fluid slot, and a second end communicated with the fluid slot,
- the fluid circulation path including a fluid circulating element to induce a flow of circulating fluid in the fluid circulation path, wherein the fluid circulating element, the first fluid ejection chamber, and the second fluid ejection chamber are arranged in series in the fluid circulation path between the first and second ends of the fluid circulation path.
A fluid ejection device, comprising:
- a fluid slot;
- a first fluid ejection chamber communicated with the fluid slot;
- a first drop ejecting element within the first fluid ejection chamber;
- a fluid circulation path communicated at a first end and at a second end with the fluid slot;
- a fluid circulating element within the fluid circulation path;
- a second fluid ejection chamber arranged in series with the fluid circulation element and the first fluid ejection chamber in the fluid circulation path between the first and second ends of the fluid circulation path;
- and
- a second drop ejecting element within the second fluid ejection chamber.
A method of forming a fluid ejection device, comprising:
- defining a first fluid ejection chamber having a first drop ejecting element;
- defining a second fluid ejection chamber having a second drop ejecting element;
