1. A high speed hydraulic turbine drive comprising:

  • (a) a housing;

    (b) a bearing means;

    (c) a shaft bearing support means contained in said housing and for supporting said bearing means;

    (d) a shaft supported by said bearing means and defining a shaft axis;

    (e) a turbine nozzle body defining a turbine body outlet surface and comprising a hydraulic fluid cavity and a plurality of nozzles each of said nozzles providing a passageway for hydraulic fluid to pass from said hydraulic fluid cavity to said outlet surface and defining a nozzle centerline, where each of said nozzle centerlines;

    (1) intersects said turbine body outlet surface at points of intersection on a circle having a diameter less than 12 inches and defining a nozzle exit circle which circle is concentric about said shaft axis and defines a nozzle exit plane which is perpendicular to said axis and(2) forms an angle of about 10 to 30 degrees with said nozzle exit plane;

    (f) a hydraulic fluid inlet means for providing hydraulic fluid under pressure to said hydraulic fluid cavity;

    (g) an axial flow hydraulic fluid turbine wheel solidly attached at one end of said shaft having a plurality of turbine blades, said wheel and blades being positioned adjacent to said turbine body outlet surface such that hydraulic fluid discharged from said nozzles impinge on said blades.
