Compressor

Abstract

A compressor is provided which enables easy installation of the filter even when any refrigerant suction passage cannot be provided on a cylinder side of a compression element or even when any long suction passage cannot be provided. The compressor comprises, in a sealed container 12, a drive element 14, a rotary compression mechanism 18 including first and second rotary compression elements 32 and 34, an upper support member 54 and a lower support member 56 for journaling a rotary shaft 16. The upper support member 54 and the lower support member 56 are provided with suction passages 58 and 60 for communicating with the interior of upper and lower cylinders 38 and 40 at suction ports 161 and 162, respectively, and recessed noise eliminating chambers 62 and 64. Filter installation portions 180 and 182 which are recessed are provided to surround and enclose open ends of the suction passages 58 and 60. Filters 184 and 186 are inserted into and installed on the filter installation portions 180 and 182, respectively, and the filter 184 is pressed against and stopped by the upper surface of the upper cylinder 38, while the filter 186 is pressed against and stopped by the lower surface of the lower cylinder 40.

1 . A compressor comprising, in a sealed container: 
 a drive element;    a compression element;    a drive shaft for transferring a driving force of the drive element to the compression element to drive said compression element; and    a bearing member for journaling the drive shaft,    wherein refrigerant gas introduced from an outside of the sealed container is drawn into the compression element via the bearing member, and then is compressed by the compression element to be discharged to the outside of the sealed container, and    wherein a filter is fitted into a recess provided at an outlet of a suction passage of the bearing member, the suction passage leading to a suction port of a cylinder constituting the compression element, said filter being pressed against and stopped by the cylinder.    
   
   
       2 . A compressor comprising, in a sealed container: 
 a drive element;    a compression element;    a drive shaft for transferring a driving force of the drive element to the compression element to drive said compression element; and    a bearing member for journaling the drive shaft,    wherein refrigerant gas introduced from an outside of the sealed container is drawn into the compression element via a refrigerant introduction pipe, and then is compressed by the compression element to be discharged to the outside of the sealed container, and    wherein a plate-like filter is holded and fixed between the compression element and the refrigerant introduction pipe on an outlet side of the refrigerant introduction pipe.    
   
   
       3 . A refrigerating cycle using the compressor according to  claim 1 .  
   
   
       4 . A refrigerating cycle using the compressor according to  claim 2.
