Sealing structure of duplex cylinder compressor lower bearing and lower silencer

The present invention provides a sealing structure of duplex cylinder compressor lower bearing and a lower sound eliminator, which includes a lower bearing and a lower sound eliminator; characterized in that a corrugated pipe and a ferrule are set between the lower bearing and the lower sound eliminator; the corrugated pipe is set on the location where the lower sound eliminator contacts with the lower bearing non-working surface small end; lateral wall of the ferrule is provided with a convex slice, wherein the ferrule is set on the location where the lower sound eliminator contacts with the lower bearing non-working surface big end and the convex slice presses the depressed part of the lower valve sheet where to mount the screw hole; leakage between the lower bearing and the lower sound eliminator can be effectively overcome; denoise performance of the sound eliminator and work efficiency of the compressor can be enhanced; working environment of the compressor can be improved; and service life of the compressor can be prolonged.
