Muffler assembly
摘要：
A muffler comprising a housing (12) having end caps (16, 18) and partitions (32, 38, 42) which divide it into first and second expansion chambers (40, 44), a flow chamber (36), and a resonator chamber (34). An inlet tube (20) passes through end cap (16) and partitions (38) and (32) to open into chamber (34): it has perforations (58) and (62) which afford communication with chambers (40) and (36) respectively. An outlet tube (24) passes through end cap (18) and partitions (42) and (32) to open into chamber (36): it has perforations (70) which afford communication with chamber (44), and includes anti-whistle beads (72). A conversion-divergent nozzle (80) is located in tube (22) at its end opening into chamber (36). Apertures (190) are provided to afford limited flow of gas through chamber (34) from tube (20) to chamber (36).
