Abstract
A fluid valve, for a sample separation device such as for liquid chromatography, includes a rotor, a stator, and external terminals for fluidically connecting one or more components. By rotating the rotor, different fluidic coupling and/or decoupling states between components are adjustable. Ports are connectable with one or more external terminals. A first channel is formed along a first circular path. A second channel includes a first coupling point located on the first circular path and a second coupling point located on a second circular path. By rotating the rotor, a fluidic coupling between a first port and a second port can be established, by the first channel being connected with the first port and at least the first coupling point with the second channel, and by the second channel being connected at least via the second coupling point with the second port.
