Abstract

An ink supply system for feeding ink from an ink cartridge to an inkjet printer includes a dry-break valve system and two coupling elements. Preferably use is made of a hollow tappet rod as a coupling element. The valves in the system are automatically opened in a single action during coupling without introduction of air into the system. The system allows for a high volume ink flow and prevents leakage from the ink cartridge and the printer due to pressure changes.
