Inside and outside structures of discharging refrigerant in bi-directional swash plate type compressor

Abstract

There are provided inside and outside structures for discharging a refrigerant in a bi-direction swash plate type compressor, and more particularly, inside and outside structures of discharging a refrigerant in a bi-directional swash plate type compressor in which, when a discharge port for discharging a refrigerant is positioned in a rear housing, all refrigerant compressed in front and rear regions of the compressor is moved into a muffler space and is discharged when pulsation of the refrigerant is reduced. Accordingly, noise of the compressor is significantly reduced.

       5 . An outside structure for discharging a refrigerant in a bi-directional swash plate type compressor  100  in which, after a refrigerant compressed in a body  10  with a front cylinder  11  and a rear cylinder  30  is temporarily stored in each of a front discharge chamber  21  formed in a front side in the body  10  and a rear discharge chamber  23  formed in a rear side in the body  10  and in a rear housing  70  connected to the rear cylinder  30 , the refrigerant jointly flows to be discharged through a discharge port  19  formed in the rear housing  70 , characterized in that:
 the refrigerant discharged from the front discharge chamber  21  and the refrigerant discharged from the rear housing  70  are mixed together in a muffler space  29  formed outside the upper part of the body  10 , so that a pulsation of the refrigerant is offset; and   the refrigerant passes through a discharge path  27  connecting the muffler space  29  and the discharge port  19  and formed outside the body, so that the pulsation of the refrigerant is reduced.   
   
   
       6 . An outside structure for discharging a refrigerant in a bi-directional swash plate type compressor  100  in which, after a refrigerant compressed in a body  10  with a front cylinder  11  and a rear cylinder  30  is temporarily stored in each of a front discharge chamber  21  formed in a front side in the body  10  and a rear discharge chamber  23  formed in a rear side in the body  10  and in a rear housing  70  connected to the rear cylinder  30 , the refrigerant jointly flows to be discharged through a discharge port  19  formed in the rear housing  70 , comprising:
