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.

Abstract: The present invention relates to a thermal isolation, suitable for isolating the gas discharge tube (13) of a refrigerating compressor (1), where the discharge tube (13) is arranged inside an isolating tube (14), forming at least a confined space between said tubes, the novelty basically consisting in that the isolating tube (14) comprises covers (15, 17) spaced apart, the cross section of the isolating tube (14) being formed by joining together the cross sections of the spaced apart covers (15, 17). In the preferred embodiment of the invention, the isolating tube (14) comprises multiple spacers, preferably annular spacers (16), arranged around the gas discharge tube (13 and the isolating tube (14), the isolating tube (14) consisting of a number tube portions (20, 26) joined together along the extension of the gas discharge tube (13). The invention also relates to a process for assembling the thermal isolation in the gas discharge tube.
