Claims

[Scope of utility model registration request]

a striking cylinder; a striking piston slidably and tightly fitted into the cylinder; a main air chamber formed on the outer periphery of one end of the cylinder; It has a head valve that selectively opens and closes between the chamber and the main air chamber or between the upper chamber of the striking piston and the exhaust hole, and the valve piston of the spatula and dohalb is connected to the upper piston part and the lower part of the piston. The piston is divided into two parts and connected by a sound deadening filter of each piston part number annular body, so that a space between the upper chamber of the striking piston and the main chamber is closed, and a space between the upper chamber of the striking piston and the exhaust hole is formed. 1. A sound muffling device for a pneumatically driven impact tool, characterized in that when the impact piston is opened, the exhaust nib in the upper chamber of the impact piston is led out to the exhaust hole via the filter.
