Abstract
The present invention refers to a compressor with an acoustic attenuator device, preferably those used in refrigeration systems, in general. More specifically, the present invention refers to an acoustic attenuator device comprising technical, structural, and functional features capable of simplifying the method of fabricating these parts and increasing acoustic attenuation levels of hermetic compressors, in general. In this sense, the attenuator device of the present invention comprises a hollow body closed by a cover to form a structure having at least one inlet hole and an outlet hole, wherein there is provided between said hollow body and said cover at least one intermediate body dividing said structure into at least two acoustic chambers (A, A′), and is formed by a platform provided with a connecting channel, which is in fluid communication between said acoustic chambers (A, A′) and further surrounds an outlet channel, which is interconnected with said outlet hollow disposed on said cover.
