ABSTRACT:
A valve is described for loading a sample at low pressure and injecting said sample into a high pressure stream, and for priming or purging of a high pressure pump. Also described is a multi-route selection valve which allows the selection of alternate flow routes through an analyzing instrument. Both valves have a rotor (11) that can pivot about an axis (13) and at the interface (12) the rotor creates a fluid tight seal against the stator (10). The stator has a common port and n peripheral ports where n is the maximum number of peripheral ports equaling an odd integer greater than or equal to 5. The rotor has a lateral face which is comprised of a distribution channel (7) and (n+1)/2-1 switching channels (8,9). The distribution channel (7) connects the common stator port (1) independently to each of the n peripheral ports (2-6). The switching channels (8,9) each span circumferentially through an arc circle of angle 360
degrees (17). Switching channels (8) and (9) communicate flow between a plurality of adjacent peripheral stator ports as the rotor turns.
