    • Known jet turbine driven machine tools suffer considerable speed reductions when the load increases or varies. This results from interference between the spent air and the working jet. In the case of the present invention the turbine, driving a rotatable spindle with a tool holder, comprises a disc-shaped turbine rotor tightly enclosed by a turbine housing (8). The turbine rotor has peripherally arranged discrete recesses (37), each recess having a concave front actuation wall (37a) for the jet and one sidewardly arranged outlet opening (37c) in the axial direction of the rotor. The housing (8) has at least one inlet nozzle (9) directed towards the deepest section of the actuation wall (37a). A recess together with the housing forms an efficient guiding path and an expansion space for the jet medium.

    • A disposable dental prophylaxis handpiece (10) is provided having a rotor (90) with vanes (92) pivotally connected thereto. The handpiece (10) includes an entrance (30) for elevated pressure fluid and an outlet (40) for discharge of the fluid after contacting the rotor (90). The elevated pressure fluid passes from the entrance (30) into a high-pressure chamber (80). The high-pressure chamber (80) is in contact with inlet ports (74) accessing a cylinder (72) within the handpiece (10). The cylinder (72) supports the rotor (90) with a rotational axis (M) of the rotor (90) off center with respect to a central axis (N) of the cylinder (72). The elevated pressure fluid causes the rotor (90) and an attached output shaft (97) to rotate. This in turn causes a prophylaxis cup (160), coupled to the output shaft (97), to rotate. The rotor (90) includes a trunk (2) with a plurality of posts (93) extending therefrom and with vanes (92) connected to the posts (93) through hinges (94).

    • A fluid reaction device (10) is provided having a rotor (90) with vanes (92) pivotably connected thereto. The device (10) includes an entrance (30) for elevated pressure fluid and an outlet (40) for discharge of the fluid after contacting the rotor (90). The elevated pressure fluid passes from the entrance (30) into a high pressure area. The high pressure area is in contact with inlet ports (74) accessing a cylinder (70) within the device (10). The cylinder (70) supports the rotor (90) with a rotational axis (M) of the rotor (90) off center with respect to a central axis (N) of the cylinder (72). The elevated pressure fluid causes the rotor (90) and an attached output shaft (97) to rotate. The rotor (90) includes a trunk (24) with a plurality of posts (93) extending therefrom and with vanes (92) connected to the posts (93) through hinges (94). The vanes (92) can pivot from a first position collapsed against the trunk (24) to a second position spaced away from the trunk (24). The vanes (92) thus can contact a cylinder wall of the cylinder (70) while the rotor (90) rotates. Exhaust ports (76) are spaced from the inlet ports (74) and provide communication with a low pressure area which exhausts low pressure fluid to the outlet (40).
