| 20090209179 | PNEUMATIC TOOL HAVING A ROTOR WITH A WEAR-RESISTANT VANE SLOT - This invention relates generally to an improved rotor for a pneumatic abrading or polishing tool, such as an orbital abrading or polishing tool, and more particularly to such a rotor having a wear-resistant vane slot. A power abrading or polishing tool, such as a pneumatic orbital abrading or polishing tool, includes a motor having a rotor that transmits a rotational force to a carrier part having an abrading or polishing head attached thereto. The rotor is contained in a motor housing which includes an inlet passage and one or more exhaust passages. Compressed air or other suitable gas enters the motor housing through the inlet passage and causes the rotor to rotate within the motor housing. As the rotor rotates, vanes slide in and out of slots in the rotor, creating sealed chambers or compartments between adjacent vanes. As the compressed gas expands within these compartments, it pushes on the vanes, causing the rotor to rotate and the vanes to slide in and out of their vane slots. The rotor includes a metal clip lining the inside surface of the vane slots to prevent wear on the slots due to the repeated movement of the vanes in and out of the slots. | 08-20-2009 |
