Abstract

A device for supplying ink to a mosaic printer unit having several printing ink jets provided in a printer head characterized by the device having a common distributor unit to supply ink to each of the printing ink jets attached on the printer head and having a cavity receiving the printing ink. To dampen hydraulic pressure fluctuations or vibrations in the ink received in the cavity, the cavity in the neighborhood of its highest point has an elastic wall member which may be either a diaphragm closing an opening in the cavity, or an elastic tube whose interior is in communication with the atmosphere.
