Scroll compressor

Abstract

A scroll compressor includes a fixed scroll having a fixed disk body and a fixed scroll body protruding from the fixed disk body; and an orbiting scroll having an orbiting disk body and an orbiting scroll body protruding from the orbiting disk body and cooperating with the fixed scroll body. The orbiting disk body has a bottom surface away from the orbiting scroll body, and the orbiting scroll body has a top surface away from the orbiting disk body. The orbiting scroll is provided with a sealing groove recessed from the top surface and a through hole extending from the bottom wall of the sealing groove to the bottom surface, and also includes a sealing strip accommodated in the sealing groove. The inner end of the sealing strip respectively defines an end gap and a bottom gap with the inner end wall and the bottom wall of the sealing groove.

         2 . The scroll compressor according to  claim 1 , wherein the through hole ( 350 ) is spaced apart from the bottom gap (G 2 ) and the end gap (G 1 ). 
     
     
         3 . The scroll compressor according to  claim 2 , wherein the sealing strip ( 360 ) completely fills the space in the sealing groove ( 330 ) other than the end gap (G 1 ) and the bottom gap (G 2 ) and covers the through hole ( 350 ). 
     
     
         4 . The scroll compressor according to  claim 1 , wherein the sealing groove ( 330 ) further includes an auxiliary groove ( 340 ) recessed from the bottom wall ( 333 ) for forming the bottom gap (G 2 ). 
     
     
         5 . The scroll compressor according to  claim 4 , wherein the auxiliary groove ( 340 ) is adjacent to the inner end wall ( 331 ) such that the auxiliary groove ( 340 ) is partially defined by the inner end wall ( 331 ); or the auxiliary groove ( 340 ) is spaced apart from the inner end wall ( 331 ). 
     
     
         6 . The scroll compressor according to  claim 1 , wherein the sealing strip ( 360 ) is thinned at the inner end ( 361 ) for forming the bottom gap (G 2 ). 
     
     
         7 . The scroll compressor according to  claim 1 , wherein the orbiting scroll ( 300 ) is further provided with an auxiliary groove ( 370 ) recessed from the bottom wall ( 333 ), the auxiliary groove ( 370 ) being in communication with the bottom gap (G 2 ). 
     
     
         8 . The scroll compressor according to  claim 7 , wherein the auxiliary groove ( 370 ) extends from the bottom gap (G 2 ) to an outer end wall ( 332 ) of the sealing groove ( 330 ). 
     
     
         9 . The scroll compressor according to  claim 7 , wherein the through hole ( 350 ) is spaced apart from the auxiliary groove ( 370 ); or the through hole ( 350 ) intersects the auxiliary groove ( 370 ). 
     
     
         10 . The scroll compressor according to  claim 7 , wherein the sealing groove ( 330 ) has two sidewalls ( 334 ) opposite each other, the orbiting scroll ( 300 ) has two auxiliary grooves ( 370 ), and each auxiliary groove ( 370 ) is adjacent to one sidewall ( 334 ) to extend along the sidewall ( 334 ). 
     
     
         11 . The scroll compressor according to  claim 1 , wherein the scroll compressor ( 10 ) is provided with a backpressure chamber ( 710 ) in communication with the through hole ( 350 ) and partially defined by the bottom surface ( 311 ).
