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.

Multi-part fluid flow structure

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.

A pressure bag for in a fluid cartridge having an opening in open connection with a channel in a wall of the fluid cartridge.

Pressure bag

A liquid supply () includes a lever () that moves in response to expansion and contraction of a variable chamber () within a liquid reservoir (). Movement of the lever () moves a ball () or sealing member () to open or close an opening () out of the liquid reservoir ().
