  • Multi-part fluid flow structure
    Patent number: 9724927
    Abstract: In one example, a multi-part flow structure with multiple flow passages includes a first part sandwiched between a second part and a third part, the parts joined together with adhesive along bonding surfaces surrounding the flow passages where each of the bonding surfaces on one part is symmetrical to and diverges from a corresponding one of the bonding surfaces on another part.
    Type: Grant

  • Multi-part fluid flow structure
    Patent number: 9440441
    Abstract: In one example, parts to be assembled into a fluid flow structure include: a first part having a first opening therein and a first adhesive bonding surface surrounding the first opening; a second part having a second opening therein and a second bonding surface surrounding the second opening; and the first and second bonding surfaces are each configured, when the parts are assembled for bonding and an adhesive is squished between the parts, to create a capillary force along the bonding surface urging adhesive away from the opening.

  • Liquid supply
    Patent number: 8919935
    Abstract: A liquid supply (30, 130, 330) includes a lever (48, 348) that moves in response to expansion and contraction of a variable chamber (42, 342) within a liquid reservoir (56, 356). Movement of the lever (48, 348) moves a ball (52, 352) or sealing member (154, 354) to open or close an opening (60, 360) out of the liquid reservoir (56, 356).
