Abstract
In some examples, a valve assembly for a fluid ejection device includes a plurality of valves to control fluid supply from a plurality of fluid sources to the fluid ejection device, each respective valve of the plurality of valves actuatable between a first valve position to provide fluid communication through a first fluid path between a first fluid source of the plurality of fluid sources and the fluid ejection device, and a second valve position to provide fluid communication through a second fluid path between a second fluid source of the plurality of fluid sources and the fluid ejection device. A common actuator, when energized, controls movement of the plurality of valves. Each respective biasing mechanism of a plurality of biasing mechanisms is to maintain the respective valve at each of the first valve position and the second valve position without energizing the common actuator.
