Abstract
An ink cartridge holder for delivering ink to printing machine ink systems, includes a cover which seals the ink cartridge holder shut and allows compressed air to build up inside the holder in order to squeeze ink out of a cartridge. A locking mechanism locks the cover in the closed position and unlocks when the cover is opened. An air valve controls the delivery and extraction of air in relation to the inside of the holder, the valve being operable depending on the locked or unlocked position of the cover. A pivoting actuator independently opens and closes the cover and is contrived in such a way that, in a first phase of motion, it moves the cover into the closed position and, in a second phase of motion, locks the cover and switches the air valve, and performs an opposite operation during an opening process.
