Abstract

707,945. Exhaust-silencers. MAXIM SILENCER CO. May 23, 1952 [Aug. 1, 1951], No. 13158/52. Class 7(2) A cylindrical shell 10, e.g. of stainless steel and which may be provided with internal laminations 11, 12, is divided by partitions 15, 18 into chambers 14, 17 and 23, and inlet and outlet conduits 13, 16, which may have anti-resonance slots 19, 20, enter and terminate substantially at the middle of the chambers 14, 17. Sets of circumferentially spaced tubes 21, 24 adjacent the wall of the shell and circumferentially staggered with respect to each other pass through the partitions 15, 18 respectively, and the ends of the tubes terminate substantially at the middle of chamber 23 in which chamber the ends of the tubes 21 may be bent inwardly towards the axis of the shell. The tubes 21, 24 may have flared inlet ends 22, 25 and anti-resonance holes 27. U.S.A. Specification 2,297,046 is referred to.
