Abstract
An isolator assembly is disclosed for supporting internal component inside a pneumatic underground piercing tool having an axial body propelled by impact forces of a striker responsive to the application of compressed air. The isolator assembly is comprised of an isolator housing mounted to the body of the piercing tool in a manner that allows relative axial movement between the body and the isolator housing. The internal components to be protected from the impact forces are mounted on the isolator housing. An elastomeric member is positioned to permit the isolator housing and internal components mounted thereon to move resiliently in the axial direction relative to the body of the piercing tool during each impact of the striker.
