摘要： A pressure regulating air valve assembly (100) for a pneumatic tool (90) is disclosed that is movable between an open position and a closed position such that the maximum pressure in the tool is limited to a predetermined value. The valve assembly include a fitting (110) with a central aperture (112) and an upper portion (114). A valve plate (130) is disposed in the fitting, and a collar (140) having an aperture (146) is retained in the fitting. A proximal end of a tubular piston (120) extends through the aperture, and a spring (118) biases the piston toward an open position. When the pressure in the hand tool exceeds a predetermined value, the pneumatic force on a distal annular head (126) of the piston urges the piston toward the valve plate (130), closing the valve. The valve plate may include a centering portion (134) and an elastomeric panel (136).

摘要： A pneumatic tool (610) and a muffler assembly (600) therefor, for quieting the operation of the pneumatic tool, are disclosed. In one embodiment, the muffler assembly (600) is slidably disposed within the exhaust passage (616) and includes a tube member (602) having a proximal flange (604), an intermediate tubular portion (606) with apertures (608), and a distal receptacle (620). The tubular portion may include a blocking plate (618) therein. A porous, sound-deadening panel (622) is disposed about the tubular portion, and a diffuser panel (630) is disposed in the distal receptacle. A perforated end cap (624) holds the muffler assembly in place. In operation, the exhaust enters the tube member, is directed transversely through apertures in the tubular portion and through the porous panel, then back into the distal portion of the tube member, through the diffuser panel, and exits through the end cap.
