Liquid jet recorder

摘要

A liquid jet recorder having a capillary tube with one end connected by a filter to a liquid pump and the other end formed in a nozzle for directing a recording jet of liquid onto a recording carrier, an electromagnet having a core and winding and a permanent magnet carried by the capillary tube and arranged in an air gap of the electromagnet characterized by the core of the electromagnet comprising an inner tube having the winding arranged thereon with the inner tube and winding coaxially surrounding the capillary tube. Preferably, the electromagnet includes an outer tube having an extension and the inner tube has an extension which forms the poles of the electromagnet and includes a centering sleeve of non-magnetizable material arranged between the inner and outer tube to determine the air gap between the two extensions.
