ABSTRACT:
A turbine for a dental handpiece. The turbine (10) includes a rotor housing (16) fabricated of a ceramic material, the rotor housing defining a cylindrical rotor chamber (18) therein. An inlet port (20) is provided in the rotor housing (16) for placing the rotor chamber in fluid communication with a source of pressurized fluid, and an outlet port (22) is provided for exhausting the pressurized fluid from the rotor chamber (18). The turbine (10) also includes a rotor member (24) mounted in the rotor chamber (18) of the rotor housing, the rotor member also being fabricated of a ceramic material. The rotor member (24) defines a first end portion (28) which is received through an opening (38) provided in the rotor housing (16) for engaging and supporting a dental tool member (14). The rotor member (24) also includes a rotor disk (32) which carries a plurality of blades (34), and which is selectively rotated by the flow of pressurized fluid within the rotor chamber (18).
