ABSTRACT:
A high speed turbine handpiece includes a housing with a turbine wheel chamber and a flow passage for air terminating in a nozzle opening on the periphery of the turbine wheel chamber as well as a discharge passage from the chamber to the exterior of the housing. An integrally formed turbine wheel in the chamber has a hub with two axially spaced sets of vanes extending about its circumference with the blades of one set circumferentially offset from the blades of the other set. The nozzle is aligned with the axial spacing or channel between the sets of vanes and is dimensioned to overlap the adjacent edge portions of the vanes so that air entering through the nozzle impinges on both sets of vanes.
