Abstract
Description
도 4는 본 발명에 따른 공명형 소음기의 실험장치.
Claims (3)
- 유체가 통과하는 통로의 외부에 길이방향으로 다수개 배열되고, 내부에 관통된 홀을 가지는 중공형의 와셔;상기 와셔의 외부를 감싸면서 형성되어 공명음을 저감시키면서 흡음재의 비산을 방지하도록 다수개의 타공이 관통형성된 타공판;상기 타공판의 외측에는 형성되어 소음을 흡음하는 흡음재; 및상기 흡음재의 외측을 둘러싼 마감재가 포함되어 형성되는 것을 특징으로 하는 흡음공명형 소음기.
- 제1항에 있어서,상기 와셔는 사각형의 홀과 사각형의 형상을 가지며 흡음공명기의 단면형상도 사각형인 것을 특징으로 하는 흡음공명형 소음기.
- 청구항 1에 있어서,상기 와셔는 일정간격으로 배치되며 그 간격이 4 mm인 것을 특징으로 하는 흡음공명형 소음기.
