Pneumatic tool with a reverse valve having an overdrive

摘要: The invention is a pneumatic tool with reverse valve having an overdrive. In particular, the includes a housing, rotor, rotatably mounted within an output shaft operatively coupled to and pressure chambers defined between housing rotor. A pneumatic reverse valve having overdrive the rotor. provides increased torque increased speed output shaft. controls flow of pressurized air multi-chambered motor of such that the direction can be reversed number of pressure chambers receiving pressurized selected regardless direction.
