Silencers for gas discharge devices employing easily replaceable cartridges utilizing juxtapositioned layers of wire mesh and porous absorbed material which dissipate exhaust noises of an exhaust system and deflect under pressure of the exhaust gases to provide a self cleaning function.
Claims23
An air exhaust silencer comprising:
- a housing having an air inlet means at one end of said housing for attachment to an air exhaust and at least one exhaust port, and
- a detachably mounted cartridge axially arranged within said housing,
- said cartridge comprising a plurality of contiguous layers of wire mesh and resilient porous material arranged sequentially in the path of movement of all of the air flow under pressure through the silencer,
- said layers of resilient porous material confined between adjacent layers of wire mesh deflect under pressure surges of the air passing therethrough to substantially prevent premature loading of the porous material and excessive flexing and disintegration thereof.
