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.

Abstract: A print liquid supply sub-assembly, the print liquid supply sub-assembly to connect to a printer to provide a print liquid to the printer may include a print liquid output to connect to a print liquid input of the printer; a first fluidic channel upstream of the print liquid output comprising a first fluidic valve to prevent the print liquid from entering a supply container upstream of the first fluidic valve; and a second fluidic channel upstream of the print liquid output fluidically coupled to the first fluidic channel comprising a second fluidic valve to selectively prevent the fluid from passing out of the supply container downstream from the second fluidic valve.

Abstract: A bag-in-box fluid supply may include a bag comprising a spout extending therefrom, the spout including a flange coupled to a surface of the bag and comprising a lip formed on the spout distal to the bag; a box formed around the bag to maintain the bag therein; a wedge to wedge a surface of the box between the lip and a surface of the bag; and a fluid interface to fluidically interface with the spout of the bag, the fluid interface including a fluidic channel and a collar disposed on a first end of the fluidic channel to secure the fluid interface to the spout.

Abstract: A fluid supply component for a replaceable fluid supply may include a channel fluidically coupled to a pliable fluid supply bag; a ball housed within the channel; and a gasket to prevent movement of the ball into the fluid supply bag; wherein the valve prevents fluid from entering the fluid supply bag while the fluid supply bag imparts a negative fluidic pressure.

Abstract: A print module includes a printhead die, an input regulator to regulate input fluid pressure to the die, and an output regulator to regulate output fluid pressure from the die. A method includes receiving fluid at an input regulator to a print module, creating a fluid pressure differential within the print module between the input regulator and an output regulator, flowing fluid from the input regulator through a printhead die and to an output regulator using the pressure differential, and drawing fluid from the output regulator.
