Abstract

869,236. Gaseous current silencers. MARUO, H. May 1, 1958 [May 6, 1957], No. 13900/58. Class 7(2). An internal combustion engine exhaust silencer, or an exhaust or suction silencer in fluid pipe lines, has an entry 9 and exit 10 intercommunicating via a diffuser chamber 16, openings 17 and a pierced-wall spiral 4, a resonance pocket 8 being in communication with the spiral 4 or with the chamber 16 via openings 6.
