Hermetic type compressor

Abstract

A hermetic type compressor is provided in which suction port is offset arranged in the rotating direction side of rotor from the upstream of suction port with respect to the flow of the cooling medium at the front of suction port with respect to opening of suction tube, so that low-temperature cooling medium is supplied from the upstream of suction port with respect to the flow of the cooling medium at the front of suction port, the low-temperature cooling medium is efficiently suctioned from suction port, and the low-temperature cooling medium is supplied to cylinder.

1 . A hermetic type compressor comprising:
 an electrically operated element accommodated in a sealed container and including a stator and a rotor;   a compression element driven by the electrically operated element; and   a suction tube communicating with an inside and an outside of the sealed container and including an opening that opens to the inside of the sealed container; wherein   the compression element is elastically supported by a coil spring, and includes a shaft that rotates with the rotor, a cylinder forming a compression chamber, and a suction muffler forming a noise deadening space communicating with the cylinder; and   a suction port linking the noise deadening space and a space in the sealed container to communicate with each other is formed in the suction muffler, the suction port being offset arranged in the rotating direction of the rotor with respect to the opening.   
     
     
         2 . The hermetic type compressor according to  claim 1 , wherein the opening and the suction port are arranged so as to at least partially overlap with each other in a projection view seen from the shaft center direction of the opening. 
     
     
         3 . The hermetic type compressor according to  claim 1 , further comprising a wall part projecting towards the inner surface of the sealed container in a rotating direction side of the rotor of the suction port. 
     
     
         4 . The hermetic type compressor according to  claim 1 , wherein an outer wall surface facing the inner surface of the sealed container is formed in the suction muffler; and
 the suction port is arranged on the outer wall surface of the suction muffler.   
     
     
         5 . The hermetic type compressor according to  claim 1 , wherein an opening area of the opening is greater than an opening area of the suction port.
