Abstract: A turbine-driven sander includes a minimum of one-piece sealed housing members so interconnected as to form a nozzle, a turbine chamber, and a valve chamber. A plurality of elongated support members are integrally formed on a housing member. Fasteners are inserted in the elongated support members to clamp the housing members together. A flap valve mounted in the valve chamber opens the turbine chamber to a source of vacuum, thereby driving a turbine rotatably mounted in the turbine chamber. This rotation in turn vibrates a platen through a direct-drive system. The platen is supported upon one of the housing members by two platen support members. A noise attenuation system at the front end of the housing includes a two-passage nozzle which is curved to interrupt the line of sight from a turbine air inlet to the turbine. A side branch resonator communicates with the nozzle via noise-attenuating holes in a cover plate located above the nozzle. The nozzle configuration and the resonator coact to attenuate turbine air inlet noise and turbine vane noise.

Abstract: A turbine-driven sander includes a switching system having a double-flap valve adjacent a passageway intermediate the turbine and a source of vacuum. One flap valve is a toggle which is actuated to open or close a bypass aperture, and which is connected to close and open, respectively, the other flap valve, which is mounted in the passageway. When the toggle opens the bypass aperture the turbine stops; conversely, when the toggle closes the bypass aperture, the turbine becomes activated and remains activated until the toggle opens the bypass aperture or the source of vacuum is removed or no longer produces a vacuum. When activated, the turbine vibrates a platen through a direct drive system.
