초록 ▼

A fluid transport apparatus facilitates flow of fluid from a source to a receptacle. The fluid transport apparatus includes a fluid transport conduit for transport of fluid through the conduit, the conduit being coupled between a fluid supply and a fluid receptacle, a compressor conduit proximate the fluid transport conduit along a portion of the fluid transport conduit between the fluid supply and the fluid receptacle, and a pump coupled to the compressor conduit for injecting fluid into the compressor conduit, and a vent that is operated to selectively enable pressurization and venting of the compressor conduit to compress and decompress the portion of the fluid transport conduit proximate the compressor conduit to pump fluid through the fluid transport conduit.

1. A phase change ink imaging device comprising: a melting element for melting solid ink sticks to produce melted ink;a melted ink collector for collecting melted ink produced by the melting element;a melted ink transport apparatus for transporting melted ink from the melted ink collector;a melted ink reservoir for storing melted ink received from the melted ink transport apparatus;a print head for receiving melted ink from the melted ink reservoir; andthe melted ink transport apparatus further comprising: a double conduit having an ink transport conduit and a compressor conduit, the ink transport conduit being located within the compressor conduit of the double conduit, an outlet end of the ink transport conduit of the double conduit being coupled to the melted ink reservoir and an inlet end of the ink transport conduit of the double conduit being connected to the melted ink collector;a fluid pump that is fluidly coupled to an inlet of the compressor conduit;a venting valve fluidly coupled to the compressor conduit of the double conduit; anda controller operatively connected to the fluid pump and the venting valve, the controller being configured to operate the fluid pump and the venting value to enable pressurizing of the compressor conduit to a pressure that deforms the ink transport conduit and venting of the deforming pressure from the compressor conduit to enable the ink transport conduit to return to a non-deformed shape and thereby pump melted ink through the ink transport conduit. 2. The phase change ink imaging device of claim 1 wherein the ink transport conduit is parallel to the compressor conduit. 3. The phase change ink imaging device of claim 1 further comprising: a common unitary wall between the ink transport conduit and the compressor conduit. 4. The phase change ink imaging device of claim 1 further comprising: a housing conduit within which the ink transport conduit and the compressor conduit are located. 5. The phase change ink imaging device of claim 1 further comprising: a check valve coupled to the ink transport conduit to prevent backflow of the melted ink into the ink transport conduit. 6. The phase change ink imaging device of claim 1 further comprising: a check valve coupled between the melted ink collector and the inlet of the ink transport conduit to enable a flow pressure in the ink transport conduit. 7. The phase change ink imaging device of claim 1 wherein the pump is an air pump and the fluid injected into the compressor conduit is air. 8. The phase change ink imaging device of claim 1 further comprising: a negative pressure source coupled to the compressor conduit through the venting valve to assist in reducing pressure in the compressor conduit. 9. A method for pumping fluid in a phase change ink imaging device comprising: melting solid ink sticks to produce melted ink;collecting the melted ink in a reservoir;injecting fluid with a fluid pump into an inlet of a compressor conduit of a double conduit to generate a pressure that deforms an ink transport conduit having an inlet that is operatively connected to the reservoir, the ink transport conduit being positioned within the compressor conduit;selectively operating a venting valve to enable pressurizing of the compressor conduit to a pressure that deforms the ink transport conduit and venting of the pressure in the compressor conduit to enable the ink transport conduit to return to a non-deformed shape to transport the melted ink received from the reservoir through the ink transport conduit of the double conduit; andreceiving the melted ink at a printhead that is operatively connected to an outlet of the ink transport conduit. 10. The method of claim 9 wherein the pressurizing and venting of the compressor conduit operates on the ink transport conduit that is parallel to the compressor conduit. 11. The method of claim 9, wherein the pressurizing and venting of the compressor conduit operates on a common unitary wall between the ink transport conduit and the compressor conduit. 12. The method of claim 9 further comprising: preventing backflow of the melted ink into the ink transport conduit with a check valve coupled to the ink transport conduit. 13. The method of claim 9 further comprising: enabling a flow pressure in the ink transport conduit with a check valve coupled to an inlet of the ink transport conduit. 14. The method of claim 9 wherein the fluid pump is an air pump that injects air into the compressor conduit. 15. The method of claim 9 further comprising: reducing pressure in the compressor conduit with a negative pressure source coupled to the venting valve.
