ABSTRACT:
A turbine wheel is encased in a closely fitting cylindrical housing filled with water. The circumference of the wheel is fitted with a plurality of chambers defined by axially extending vanes, each of which may have a radially flat portion tending to propel water tangentially following the direction of rotation of the wheel. Each chamber communicates to a respective radial conduit, and through the conduit to a central manifold. Gas is supplied at the manifold, so rather than being injected from outside the wheel, the gas is injected into the chambers from a point radially inward of the chamber volume. Water displaced downwardly out of the bottom chambers is diverted into a bypass conduit running outside the closely fitting housing and travels upwardly to be reintroduced into the chambers as they near the top dead center position. The water is preferably introduced over a fraction of the chambers' axial dimension so that the air may be quickly displaced to the side (axially).
