FIELD: engines and pumps.SUBSTANCE: noise killer comprises case with chambers composed by webs and intake branch pipe. Said case is composed by outer cylindrical shell, its solid bottom and spherical perforated cover. Inner cylindrical shell is arranged inside the case and parallel therewith that has solid web and solid spherical cover. Said inner and outer cylindrical shells are connected by circular perforated web. Vertical webs making the active chambers filled with loose material are arranged in inner chamber formed between circular perforated web and covers. Reactive chamber is arranged under active chambers and composed by the inner cylindrical shell solid web and the part of inner cylindrical shell, circular perforated web, the part of outer cylindrical shell from circular perforated web to case bottom and its solid bottom.EFFECT: simplified design, higher efficiency of noise killing without pressure loss in noise killer.2 dwg |
