Abstract
A percussion action pneumatic tool for compacting backfill areas including a vibration isolator and a percussion mechanism. The vibration isolator includes an inner shaft and an outer sleeve attached to a pair of springs. The springs dampen vibration or feedback transferred from the percussion mechanism to the outer sleeve and felt by the operator. The percussion mechanism includes a pair of elbows and an air conduit which allows the airflow to move through a second flow path into a second air space when the valve assembly directs the airflow through the second flow path.
