  • Patent number: 10596821
    Abstract: A rocker valve includes a number of rails to transitionally connect an arm of a spring to the rocker valve such that the arm of the spring transitions across the rocker valve to actuate the rocker valve, a first side of the rocker valve to selectively engage with a valve seat based on a position of the arm of the spring relative to the first side of the rocker valve, and a number of pivot arms to pivot the rocker valve between a closed position and an open position such that the first side of the rocker valve selectively engages with the valve seat to regulate pressure inside a print head assembly.

  • Publication number: 20200009874
    Abstract: The subject matter discloses a fluid cartridge comprising a container to hold a predetermined volume of fluid, and a lid for closing the container. The lid comprises a valve-recess and an inlet valve in the valve-recess to transfer a volume of a replacement fluid in the container for replacing depleted volume of fluid in the container. A rocker valve is pivoted in the valve-recess to cover the inlet valve during a regulation phase. The rocker valve is to open the inlet valve during an actuation phase to allow the replacement fluid to enter the container. A spring element is movably disposed on the rocker valve to control actuation of the rocker valve for opening and closing the inlet valve. The spring element slides across the rocker valve, from a regulation zone of the rocker valve to an actuation zone of the rocker valve, to open the inlet valve.

  • Patent number: 8764173
    Abstract: A removable ink supply comprises an ink container including a coupler configured to removably engage a receiver of an ink supply station of an image forming apparatus. The coupler includes an end portion including an array of key holes with each key hole configured to removably receive a respective one key of an array of at least partially conductive keys of the receiver of the ink supply station. A conductive component of the coupler is positioned within the coupler and spaced apart from the end portion. The conductive component is in axial alignment with at least some of the respective key holes to be positioned for selective, removable contact with at least some of the respective keys of the receiver. An absence or a presence of removable contact between the conductive component and the key indicates an out-of-ink status of the image forming apparatus.

  • Patent number: 8714720
    Abstract: An ink container for an inkjet print head includes a substantially rigid body of polymer material, the body including a base and a side wall integrally formed with the base at a perimeter of the base, the body containing ink in a low pressure chamber, and the polymer material having moderate to high air permeability. A flexible film is sealed over the low pressure chamber, inwardly flexible in response to a decrease in pressure and ink volume in the low pressure chamber, and outwardly flexible in response to an increase in pressure and ink volume in the low pressure chamber. A metal is coated on a perimeter of the polymer body and on an outer exposed surface of the flexible film, the metal to form a metal coating configured to decrease the air permeability of the polymer body, the metal coating being formed from at least copper.
