Abstract

A device for circulating an ink supply to at least one inkjet print head includes at least two components that are different than the inkjet print head and through which ink flows, such as a pump and a valve for the ink. At least one ink line is connected between the components. At least one section of the ink line is embodied as a channel in a plate. The device advantageously has a compact construction and is easy to clean and service. The device has a high degree of reliability since the number of hose lines is advantageously reduced.
