ABSTRACT:
A vibration and noise attenuating construction for impact air tools, such as a chipper, includes axially reciprocal working and balancing members which move toward and away from each other. The end of one member defines a cylinder and cylinder chamber which receives a piston defined in the end of the other member. Pressurized air is introduced into the cylinder chamber causing the chamber to expand and the members to be translated axially from each other against the force of compression springs. Translation of the piston beyond an exhaust passage in the cylinder wall permits the chamber to exhaust whereupon the compression springs will drive the members toward their original position. The members constantly cycle in this manner to provide vibration attenuation.
