ABSTRACT:
A rotary valve is disclosed having a rotor and stator that utilizes at least one compression spring to provide contact between the rotor and stator. The spring(s) is configured to oppose the pressure forces that urge the rotors and stators apart and reduce the amount of torque necessary to turn the rotors in the valve while preventing leakage from between the rotor and stator. The spring(s) may be positioned within the valve by a spring locating features.
