Abstract
A multiport rotary valve has a stator with plural flow paths and a rotary valve plate having plural flow channels. The rotary valve plate defines a rotor that rotates relative to the stator to define unique plural fluid pathways from the stator, through the valve plate, and returning through the stator. Rotation of the rotary valve plate is controlled by a microprocessor, which includes an optical sensor to determine the position of the rotor.
