Abstract: A microfluidic valve can include a substrate having a microfluidic channel formed in the substrate. A sealing layer can be over the microfluidic channel. A flexible blister layer can be over the sealing layer. The flexible blister layer can include a blister formed as a distended portion with a blister volume between the flexible blister layer and the sealing layer. The microfluidic valve can be actuatable by puncturing the sealing layer by pressing on the blister. Actuating the microfluidic valve can either allow fluid to flow through the microfluidic channel or block fluid from flowing through the microfluidic channel.

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.

Abstract: A metered volume microfluidic device can include fluid flow microfluidics. The fluid flow microfluidics can include an inflow channel, a metered volume chamber positioned to receive working fluid from the inflow channel, a metered volume outflow channel positioned to receive and direct a metered volume of the working fluid when discharged from the metered volume chamber, and a capillary check valve. The capillary check valve can allow excess working fluid to exit the metered volume chamber when filling the metered volume chamber via the inflow channel. The capillary check valve can also prevent excess working fluid that has passed there through from being reintroduced into the metered volume chamber when the working fluid is discharged into the metered volume outflow channel.

Abstract: A fluid ejection and circulation apparatus may include a fluid ejection die, the pressure regulator, a first standpipe, a second standpipe and a crossflow passage. The pressure regulator has a fluid chamber. The first standpipe is between the fluid chamber and the fluid ejection die. The first standpipe has a first port above the fluid ejection die. The second standpipe extends alongside the first standpipe. The second standpipe has a second port above the fluid ejection die. The crossflow passage connects the first standpipe and the second standpipe.

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.
