International Classification:

B41J 2175

US Classification:

347 86

Abstract:

An ink supply for an inkjet printer is provided with a main reservoir, which is typically maintained at ambient pressure. The main reservoir, which has flexible side walls supported by a rigid frame, is coupled to a variable volume chamber via a check valve which allows the flow of ink from the reservoir to the chamber and limits the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet which is normally closed to prevent the flow of ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer.

Appl. No.:

8/566642

Inventors:

David O. Merrill - Corvallis OR

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

B41J 2175

US Classification:

347 86

Abstract:

The ink supply has an ink reservoir, a valve, a pressurizable chamber, and an outlet. The refilling is accomplished by directing ink from the outlet into the reservoir while the chamber is otherwise unpressurized so that the valve remains slightly open to permit the refill flow therethrough.

Appl. No.:

8/566643

Inventors:

David O. Merrill - Corvallis OR

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

B41J 2175

US Classification:

347 86

Abstract:

The assembly includes a valve member that occludes and releases ink flow from the container. The valve member also has a head that moves to open an air vent as ink is being released and to close the vent when ink flow is occluded. The valve member may be operated automatically or manually.

International Classification:

B41J 2175

US Classification:

347 86

Abstract:

A fluid interconnect for coupling an ink supply to an ink-jet printer includes a fluid outlet and a fluid inlet. The fluid outlet has a housing with one end in fluid communication with the ink supply and the other end sealed by a septum. A sealing member is positioned within the housing and is biased against the septum by a spring to form a second seal. The fluid inlet includes a hollow needle having one end in fluid communication with the print head and the other end defining a hole. A sliding collar surrounds the needle and is biased into a sealing position in which it seals the hole. The fluid inlet and fluid outlet can be coupled by pressing them together. During the coupling process, the needle pierces the septum to enter the housing and press the sealing member away from the septum. This allows fluid to flow from the ink supply, into the housing, passed the sealing member, into the hole in the needle and to the print head. Upon decoupling, the needle is withdrawn to seal the septum.

US Classification:

347 86

Abstract:

An ink supply for an ink-jet printer is provided with a main reservoir, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet which is normally closed to prevent the flow of ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer.

Assignee:

International Classification:

B41J 2175
F16K 5100

US Classification:

347 85

Abstract:

A fluid interconnect between an ink supply and an ink-jet printer has an outlet assembly and an inlet assembly. The outlet assembly has a hollow tube with a lateral hole, a guide member and a sealing member with a catch. The inlet assembly has a poppet valve and at least one compliant finger. When the outlet assembly is inserted into the inlet assembly, the sealing member is moved from a closed position, in which the sealing member covers the lateral hole to occlude ink flow, into an open position, in which the lateral hole is exposed so that ink may flow through the outlet assembly. At the same time, the compliant finger engages the catch on the sealing member. As the outlet assembly is extracted from the inlet assembly, the compliant finger moves the sealing member back to a closed position to cover the lateral hole to occlude ink flow through the outlet assembly.
