Abstract
The present invention relates to a working liquid suction device of a closed compressor, which comprises a suction pipe and a noise suppressor, wherein the suction pipe is communicated with a closed outer shell of the compressor, and the suction pipe enables working liquid to flow into an inner part from an outer part; the noise suppressor is arranged in the closed outer shell, and the noise suppressor can suppress the noise of the working liquid and transfer the working fluid to the side of a compression chamber. The working liquid suction device of a closed compressor is characterized in that the working liquid suction device of a closed compressor is also provided with a communicating pipe, one end of the communicating pipe is inlaid on an inlet of the noise suppressor, the other end of the communicating pipe covers the suction pipe, and the other end of the communicating pipe is also connected with the periphery of an outlet of the suction pipe. The working liquid suction device of a closed compressor manufactures the communicating pipe by elastic plastic materials and enables the noise suppressor to be connected with the suction pipe, and therefore, the working liquid can be transferred to the noise suppressor without leakage. Particularly, because the diameter of an expansion part of the side of an inlet of the communicating pipe is larger than that of the suction pipe, the working liquid entering by the suction pipe can truly well enter the noise suppressor. Because the communicating pipe is made of the elastic materials, the noise suppressor can be well connected with the outlet of the suction pipe even if distance change exists between the noise suppressor and the inner wall of the closed outer shell.
