摘要
A muffler assembly for a pneumatic power tool includes a tube member defining an interior volume. The tube member includes an upper segment and a lower segment. The upper segment defines a first diameter and includes a closed upper end to inhibit fluid communication with the interior volume therethrough, a lower end, a first portion defining a plurality of vents to enable fluid communication with the interior volume therethrough, and a second portion defining a continuous surface to inhibit fluid communication with the interior volume therethrough. The lower segment defines a second diameter greater than the first diameter and includes an upper end in fluid communication with the lower end of the upper segment, a lower end, a first portion defining a plurality of vents to enable fluid communication with the interior volume therethrough, and a second portion defining a continuous surface to inhibit fluid communication with the interior volume therethrough.
