Abstract

In an example, a selection valve of a fluid supply system is disclosed. The selection valve selectively couples a source of pressurized air to one of first and second fluid supply cartridges, in the fluid supply system, to provide fluid to a printhead, the one of first and second fluid supply cartridges being coupled to the source of pressurized air at a time and other fluid supply cartridge being vented to the atmosphere. The selection valve includes a sleeve to provide interconnections with the source of pressurized air, the first and second fluid supply cartridges, and the atmosphere. Further, the selection valve includes a core disposed rotatably inside the sleeve to selectively couple the one of first and second fluid supply cartridges to the source of pressurized air and the other fluid supply cartridge to the atmosphere for switching the pressurized air between the first and second fluid supply cartridges.
