Rotary valve

摘要

A rotary valve (300) having a rotor (320) and stator (310) that utilizes at least one compression spring (350) to provide contact between the rotor (320) and stator (310). The spring (350) is configured to oppose the pressure forces that urge the rotors (320) and stators (310) apart and reduce the amount of torque necessary to turn the rotors (320) in the valve (300) while preventing leakage from between the rotor and stator. The spring (350) may be positioned within the valve (300) by a spring locating features.
