NOISE REDUCING DEVICE OF AN ENCLOSED RECIPROCATING COMPRESSOR HAVING A SIDE BRANCH RESONATOR FORMED IN A DELIVERY MUFFLER

摘要

The present invention discloses a noise reduction device of a hermetic reciprocating compressor. The present invention is installed on one side of the muffler plate assembled in the cylinder block and the valve cover to form a primary room, the muffler cup is installed on the outlet side of the muffler plate and connected to the muffler plate through a connecting passage to form a secondary room In the hermetic reciprocating compressor having a discharge muffler, the cylinder block is formed to have a predetermined length and depth in parallel with a connecting passage 326 for communicating the valve cover 330 and the muffler cup 324, and the cylinder block. And a geodetic resonator 328 surrounded by the cylinder block during assembly to form a predetermined volume of space. Therefore, the noise having a specific frequency among the noises such as the blow sound of the valve or the pulsation sound during compression can be removed by using a geodetic resonator with a simple structure that does not occupy a separate installation space.
