Pneumatic impact tool having improved vibration and noise attenuation |
摘要 |
Vibration and noise are considerably reduced in a pneumatic impact tool by structure generating a novel vibration dampening action during tool operation. Dampening chamber members in the tool undergo compression when the reciprocating work member recoils as a method for such attenuation. Resilient seal members are further included in the tool construction to assist with the vibration dampening effect. Inclusion of oppositely biased spring members in the tool construction still further reduces the vibration attenuation.
