Abstract
1,116,709. Exhaust silencers. ATLAS COPCO AKTIEBOLAG. Aug. 31, 1966 [Sept. 10, 1965], No. 38768/66. Heading F1B. [Also in Division B3] A pneumatic screwdriver or drilling machine 10, Fig. 1, comprises a rotary vane-motor, an annular exhaust duct 32, and two rings 36 of rigid porous material, which reduce the noise of the exhaust issuing from the exhaust passages 27. The rings may be made of porous sintered bronze having lugs 37, for axially spacing the rings. Three porous rings (40), Fig. 4 (not shown), may be provided, spaced by sleeves (41). In a modification, the exhaust duct (32), Fig. 6 (not shown), is arranged so that the exhaust is directed forwardly on to the work. In a further modification, the duct (32'), Fig. 7 (not shown) is arranged adjacent the hand grip (30). In another modification, the duct (32"), Fig. 8 (not shown), has a flange 53, and radial outlets 54 direct the exhaust in a radial direction.
