Cladding for air-suction machine incorporates resonance chamber, cladding-wall, air filter and sound-radiating components

摘要

The cladding (12) completely enclosing the air-suction machine is sealed against its environment. A resonance chamber (19) communicates with the air suction path of the machine; the air suction (17) is conveyed through the wall (18) of the cladding. The air suction incorporates an air filter (15). The cladding contains further sound-radiating components (20).
