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 communicated with the fluid slot and including a second drop ejecting element, a fluid circulation path communicated with the first fluid ejection chamber and the second fluid ejection chamber, and a fluid circulating element within the fluid circulation path.
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 communicated with the fluid slot and including a second drop ejecting element;
- a fluid circulation path communicated with the first fluid ejection chamber and the second fluid ejection chamber, wherein the fluid circulation path includes a first portion communicated with the first fluid ejection chamber, a second portion communicated with the second fluid ejection chamber, and a channel loop between the first portion and the second portion, wherein the first portion of the fluid circulation path is to direct fluid in a first direction, and the second portion of the fluid circulation path is to direct fluid in a second direction opposite the first direction;
- and
- a fluid circulating element within 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 second fluid ejection chamber communicated with the fluid slot;
- a second drop ejecting element within the second fluid ejection chamber;
- a fluid circulation path communicated at a first end with the first fluid ejection chamber and communicated at a second end with the second fluid ejection chamber, wherein the fluid circulation path is to direct fluid in a first direction between the first fluid ejection chamber and the second fluid ejection chamber and in a second direction opposite the first direction between the first fluid ejection chamber and the second fluid ejection chamber;
- and
- a fluid circulating element within the fluid circulation path.
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;
- defining a fluid circulation path having a fluid circulating element, wherein defining the fluid circulation path includes providing the fluid circulating element within the second portion of the fluid circulation path;
- communicating the first fluid ejection chamber and the second fluid ejection chamber with a fluid slot;
- communicating a first portion of the fluid circulation path with the first fluid ejection chamber;
- and
- communicating a second portion of the fluid circulation path with the second fluid ejection chamber.
