Abstract

A rendering apparatus and a carriage for a rendering apparatus are provided, the carriage comprising a repository for a rendering fluid and an integrated mechanical pressure supply to pressurise the repository.

First claim

The invention claimed is:

1. A rendering apparatus comprising
a carriage;
a repository for a rendering fluid mounted on the carriage;
an integrated mechanical pressure supply to pressurise the repository, the integrated mechanical pressure supply also mounted on the carriage to generate pressure to pressurize the repository on the carriage; and
a gear-rack arranged along a path of the carriage, a gear engaged with the gear-rack being connected to the integrated mechanical pressure supply to supply energy to the integrated mechanical pressure from movement of the carriage.

2. The apparatus of claim 1 , wherein the mechanical pressure supply comprises a pump.

3. The apparatus of claim 2 , wherein the mechanical pressure supply comprises a driveshaft and a gear connected to the pump.

4. The apparatus of claim 2 , wherein the pump comprises at least one inlet conduit supplying the rendering fluid to the pump.

5. The apparatus of claim 2 , wherein the pump comprises at least one outlet conduit connecting the pump to the repository.

6. The apparatus of claim 1 , further comprising a rendering fluid bag in the repository.

7. The apparatus of claim 6 , further comprising an integrated mechanical blower mounted on the carriage to supply air pressure to the rendering fluid bag.

8. The apparatus of claim 7 , wherein the mechanical blower comprises a driveshaft and a gear.

9. A rendering apparatus comprising:
a carriage,
a repository for a rendering fluid coupled to the carriage;
a mechanical pressure supply coupled to the carriage, the mechanical pressure supply to pressurise the repository;
a carriage path guide;
a drive mechanism to cause simultaneous movement of the carriage, the repository, and the mechanical pressure supply along the carriage path guide; and
a gear-rack arranged along the carriage path guide, a gear engaged with the gear-rack being connected to the mechanical pressure supply to supply energy to the mechanical pressure from movement of the carriage.

10. A rendering apparatus as claimed in claim 9 , further comprising a gear-rack.

11. A rendering apparatus as claimed in claim 9 , wherein the mechanical pressure supply comprises a pump.

12. A rendering apparatus as claimed in claim 11 , wherein the mechanical pressure supply comprises a driveshaft and a gear connected to the pump.

13. A rendering apparatus as claimed in claim 9 , further comprising an integrated mechanical blower to supply air pressure to a rendering fluid bag.

14. A rendering apparatus as claimed in claim 13 , wherein the mechanical blower comprises a driveshaft and a gear.

15. A rendering apparatus comprising
a carriage;
a repository for a rendering fluid mounted on the carriage; and
an integrated mechanical pressure supply to pressurise the repository, the integrated mechanical pressure supply also mounted on the carriage to generate pressure to pressurize the repository on the carriage;
wherein the mechanical pressure supply comprises a pump; and
wherein the mechanical pressure supply comprises a driveshaft and a gear connected to the pump;
the apparatus further comprising a gear-rack arranged along a path of the carriage, the gear engaged with the gear-rack to supply energy to the pump from movement of the carriage relative to the gear-rack.

16. The apparatus of claim 15 , further comprising a blower mounted on the carriage, the blower also has a gear engaged with the gear-rack to supply energy to the blower from movement of the carriage relative to the gear-rack.

17. The apparatus of claim 1 , wherein the repository comprises:
a bag for containing the rendering fluid; and
a pressure bag expandable with pressure from the mechanical pressure supply to apply pressure to the bag for containing the rendering fluid.

18. The apparatus of claim 1 , wherein:
the repository comprises a plurality of compartments for containing different rendering fluids; and
each compartment of the repository is connected through a valve to a print head that comprises nozzles for deposition of the rendering fluids.

19. The apparatus of claim 18 , wherein each of the compartments in the repository comprises a different color of ink as the rendering fluid.
