Abstract
In one example, a single valve assembly having multiple bi-stable cam actuated valves each to open and close a corresponding one of multiple separate liquid flow channels. In one example, a liquid recovery system for an inkjet type dispenser includes a reservoir, an interconnect to connect to a removable container, a flow channel from the reservoir to a printhead unit and back to the reservoir and from the reservoir to the interconnect, a pump to pump ink from the reservoir along the flow channel, and a bi-stable cam actuated valve to open and close the flow channel downstream from the pump between the reservoir and the interconnect.
