Abstract (en)
In a pneumatic-powered tool (100), exhaust air may be discharged radially from an air driven motor (240) into a motor chamber. In the motor chamber (280), the exhaust air may follow a flow path around a periphery of the air driven motor, and be discharged into an exhaust chamber (272). From the exhaust chamber, the exhaust air may be discharged from the tool in a radial direction. A plurality of exhaust slots (286) may be defined in a peripheral wall (284) of the motor chamber, at a portion of the motor chamber that is adjacent to the exhaust chamber. The plurality of exhaust slots may guide exhaust air from the motor chamber into the exhaust chamber. A guide surface of the exhaust chamber may guide air out of the exhaust chamber in an axial direction.
