  • Patent number: 10118390
    Abstract: An inkjet print head including a plurality of single jet elements. Each of the single jet elements includes an aperture configured to eject ink during a jetting event, and a channel for receiving ink, the channeling including a recirculation portion configured to receive ink during a non-jetting event. The print head also includes a first manifold structured to supply ink to the channel, and a second manifold structured to receive ink from the recirculation portion of the channel. The ink flows from the inlet portion to the second outlet portion during non-jetting through the second outlet portion.
    Type: Grant
    Filed: October 23, 2017
    Date of Patent: November 6, 2018

  • Patent number: 9694582
    Abstract: An inkjet print head including a plurality of single jet elements. Each single jet element includes an aperture configured to eject ink during a jetting event, a channel for receiving ink. The inkjet print head also includes a first manifold structured to supply ink to the channel; and a plurality of recirculation paths. Each recirculation path configured to receive ink during the jetting event and a non-jetting event. Each recirculation path includes a recirculation channel connected to the channel for receiving ink, the recirculation channel is formed by half-etching one of the steel plates that forms part of the each of the single jet elements and the recirculation paths, and a second manifold structured to receive ink from the recirculation channel. The ink flows from the first manifold to the second manifold through each of the plurality of single jet elements and the recirculation paths during a non-jetting event.
