Abstract
998,874. Exhaust silencers. F. H. KUFFIN. July 2, 1962 [July 7, 1961], No. 24581/61. Heading F1B. An internal unit for an exhaust silencer comprises an inlet pipe 10 and open-ended intermediate and outlet pipes 12, 11, the end 18 of the inlet pipe being blocked and provided with slots or apertures 19 through which the gases flow to enter the adjacent end of the pipe 12. The unit is surrounded by an oval casing which forms expansion chambers 22, 23, 24, which casing may terminate before the end of pipe 11 or beyond the end thereof. More than one unit 10-12 may be inserted in a single casing or several casings each with a single unit therein may be connected in series. The pipes 12, 11, are provided with perforations 21, 20, so that some of the gases flow therethrough to enter pipe 11 at points intermediate its ends. The chamber may be packed with sound absorbing material.
