Abstract
A turbine is mounted in an annular cavity, and is provided peripherally with exhaled air, which is exhausted axially therefrom. A fixed stator has axially extending, chordally penetrating slots therein, and a calibrating ring adjustable for partial occlusion of the slots. The rotor within the stator rides on jeweled bearings, and comprises fiberglass sheets bonded to the shaft and extending outwardly therefrom. Turns of the rotor are coupled to a stopwatch-type accumulator mechanism by substantially colinear, bent interfering shafts which define a low friction low inertia universal joint. The stopwatch accumulator is readily detachable for sterilization of the turbine/housing portion.
