ABSTRACT:
A noise suppressing apparatus for a hermetic reciprocating compressor. A soundproof chamber is provided at a lower shell. A suction pipe passes through the soundproof chamber and is divided into inner and outer suction pipes spaced from each other in the soundproof chamber. The inner suction pipe is connected to a suction muffler in such a manner that the inner end of the inner suction pipe is inserted in a spring, and a resilient member is formed about the inner end and the spring and inserted into the suction muffler. Thus the apparatus can diminish noise as well as heat transfer, thereby achieving high efficiency.
