Abstract:

A pneumatic remover assembly having a central housing with a reciprocating internal mass and spring, a first end unit having a spool-type valve for activating the remover, a second end unit having various conduits disposed therein for introducing and exhausting compressed air in and out of the remover, and a unique adjustment ring which is capable of adjusting the flow rate of the compressed air which is introduced to the remover, thereby regulating the striking intensity of the remover. The adjustment ring comprises an airflow groove disposed within the interior surface of the adjustment ring which is in contact with the second end unit of the remover assembly. This airflow groove has a gradually increasing depth along its length and is in continuous communication with the compressed air injection conduit disposed in the second end unit.
