Popis: | A sound reduction apparatus for a pneumatic type nailing machine in which a driving piston is driven by compressed air to drive a nail and the compressed air is exhausted from an exhaust port after driving is provided. The sound reduction apparatus includes a sound reduction chamber configured for receiving the compressed air from the exhaust port and exhausting the air after driving. The sound reduction chamber includes a wall defining a plurality of exhaust slits extending circumferentially about the sound reduction chamber. The exhaust slits are constructed and arranged to exhaust the compressed air from the sound reduction chamber in a substantially laminar flow thereby reducing an intensity of exhaust sound. |
