Abstract
A fluid ejection cartridge includes a fluid container that has both a fluid inlet and a fluid outlet. The fluid ejection cartridge has one or more fluid ejectors fluidically coupled to the fluid container outlet and a fluid valve fluidically coupled to the fluid container inlet. The fluid ejection cartridge has a filter assembly having a compliant portion with an internal volume fluidically coupled to the fluid container outlet such that the internal volume changes when fluid flows into the fluid container.
Claims55
A fluid ejection cartridge comprising:
- a fluid container having a fluid inlet and a fluid outlet;
- at least one fluid ejector fluidically coupled to said fluid container outlet;
- a fluid regulator fluidically coupled to said fluid container inlet;
- and
- a filter assembly having a compliant portion with an internal volume fluidically coupled to said fluid container outlet wherein said internal volume changes when fluid flows into said fluid container.
A fluid ejection cartridge comprising:
- a fluid container having a fluid inlet and a fluid outlet;
- at least one fluid ejector fluidically coupled to said fluid container outlet;
- a fluid regulator fluidically coupled to said fluid container inlet;
- and
- a filter assembly disposed within said fluid container, comprising:
- a thermoplastic polymer filter frame;
- and
- a compliant polymer filter material attached to said thermoplastic polymer filter frame, forming a compliant portion, having an internal volume fluidically coupled to said fluid container outlet wherein said internal volume changes when fluid flows into said fluid container.
A method of manufacturing a fluid ejection cartridge comprising the steps of:
- forming a fluid container having a fluid inlet and a fluid outlet;
- creating at least one fluid ejector fluidically coupled to said fluid container outlet;
- and
- mounting a filter assembly to said fluid outlet, wherein said filter assembly includes a compliant portion with an internal volume fluidically coupled to said fluid container outlet wherein said internal volume changes when fluid flows into said fluid container.
The fluid ejection cartridge made by method 33.
A method of using a fluid ejection cartridge comprising the steps of:
- containing a fluid within a fluid container having a fluid inlet and a fluid outlet;
- coupling at least one fluid ejector to said fluid container outlet;
- regulating said fluid in said fluid container at a predetermined level;
- filtering said fluid through a fluid assembly having a compliant portion with an internal volume fluidically coupled to said fluid container outlet;
- and
- changing said internal volume when fluid flows into said fluid container.
