摘要

The controller mounted on pneumatic tool is driven by the compressed air. The pneumatic tool has a main body (1) and a grip section (15), which is connected at the lower end. A pneumatic motor unit provided inside the main body from there the compressed air enters through air inlet channels (17,18) whereby the controller makes to and fro motion which permits the to and fro motion of pneumatic motor unit. Rear cap unit (10) is mounted on main body and is provided with airflow seat (11) has an intake cavity (113), which is connected with air inlet channel. A control valve (20) is provided in the intake cavity, which regulates the flow direction of compressed air, whereby the air control valve has an air valve channel (21) through which compressed air passes.
