Acoustic attenuating device for compressors, preferably compressors for cooling systems, which comprises a hollow body (20) having at least one input port (22), at least one output channel (27), at least one output port (23) disposed in the at least one output channel (27), an intermediate body (24) dividing the hollow body (20) into two acoustic chambers (Α,Α'), and a connection channel (26) communicating the two acoustic chambers (Α,Α'). Said connection channel (26) comprises two sub-channels (26a, 26b), wherein one (26a) of the two sub-channels (26a, 26b) accommodates, at least partially, the output channel (27) and the other one (26b) of the two sub-channels (26a, 26b) conforms fluid communication between the two acoustic chambers (26a, 26b). The acoustic attenuating device further comprises at least one blocking means (28) disposed between the outer side of the output channel (27) and the inner side of the sub-channel (26a) which accommodates the output channel (27), wherein said blocking means (28) is capable of precluding fluid flow between the two acoustic chambers (Α,Α'), thereby reducing the amount of lubricating oil which flows out from the compressor into the cooling system. |
