    Abstract: A muffler for reducing the noise level of a noise carrying gaseous flow having a fiberglass depth type filter and a pleated paper filter mounted within a metallic canister. The depth type filter has a sufficient thickness and density to break up an acoustic wave and thereby reduce the noise level accompanying a gas flow through the filter to a predetermined level. A groove is formed in one solid portion of the metallic housing. Gas flow introduced into the housing can reach this housing portion without passing through the filter. The groove weakens this portion of the housing so that it will rupture along the groove in response to too great a gaseous pressure. The groove has a half-circle shape so that the housing portions on opposite sides of the groove will only be bent during rupture. No part of the housing will be broken off during rupture and become a dangerous projectile.

    Abstract translation: 一种用于降低带有玻璃纤维深度型过滤器和安装在金属罐内的褶皱纸过滤器的噪声携带气流的噪声水平的消音器。 深度型过滤器具有足够的厚度和密度,以破坏声波,从而将伴随着通过过滤器的气流的噪声水平降低到预定水平。 在金属壳体的一个实心部分中形成凹槽。 引入壳体的气流可以到达该壳体部分而不通过过滤器。 凹槽削弱了壳体的这一部分,使得它将响应于太大的气体压力沿着凹槽而破裂。 槽具有半圆形状,使得槽的相对侧上的壳体部分将仅在破裂期间弯曲。 房屋的任何一部分在破裂期间将被打破,成为危险的射弹。
