Air pulse noise damper for a pneumatic tool |
摘要 |
A pneumatic tool having an exhaust air noise attenuating system in which air exhausting from a rotary air vane motor is caused to pass in order through an exhaust port, past a flexible leaf damper overlying the exhaust port into a wave modulating chamber containing an air diffusion screen, and finally through ports exiting to atmosphere. The damper is illustrated in a first form as applied to the motor of an impact wrench; and is illustrated in a second embodiment as applied to a grinding tool.
