Abstract
A muffler for reducing the noise level of the air exhaust from a governed pneumatic tool. Exhaust ports in the tool housing communicate with the interior cavity of a muffler body having selectively located port holes for discharging exhaust from the cavity to atmosphere. Contained in the muffler cavity is a foraminous baffle plate centrally supported in the path of discharge between the exhaust ports of the housing and the discharge ports of the muffler body. Extending about the baffle periphery are a plurality of bypass passages defining a flow path parallel to the baffle and sized to accommodate total air flow at maximum capacity.
