Abstract: 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.

Abstract: Vibration and noise are considerably reduced in a pneumatic impact tool with structure providing novel vibration dampening and vibration isolation. The required vibration reducing components employ particular vibration dampening chamber members which dynamically interact with further included multi-part spring and elastomeric members.
