PURPOSE:To greatly reduce the number of manufacturing steps of a silencer for an enclosed compressor, by opening a hole in a part of a gas pipe and providing a cover over the hole. CONSTITUTION:To eliminate the noise of gas released from a compressor or the like, a pipe 12 through which the gas flows is bent and a hole 13 is opened in the inner section of the bent part of the pipe. A cover 14 is mounted over the hole 13. One end of the cover 14 has an opening 19 corresponding to the hole 13. End plates 15, 16 are tightly secured on the peripheral surface of the pipe 12 around the opening 19. Since the other end 18 of the cover 14 is previously closed, a silencing chamber is easily provided by mounting the cover. |
