Compressor

Abstract

A compressor includes fixed scroll (6) and revolving scroll (7) configuring compression mechanism (2), compression chamber (9), intake chamber (11), discharge port (12), muffler (16), and heat-insulating member (24) provided between fixed scroll (6) and muffler (16). After a refrigerant gas taken into intake chamber (11) is compressed by revolving scroll (7) revolving and compression chamber (9) moving while changing a volume of compression chamber (9), the refrigerant gas is discharged from discharge port (12). The refrigerant gas discharged from discharge port (12) is discharged into muffler space (14) formed by muffler (16). Heat-insulating member (24) includes heat-insulating member discharge port (25), lead valve (13), and recess (27).

1 . A compressor comprising:
 a fixed scroll and a revolving scroll configuring a compression mechanism;   a compression chamber formed between the fixed scroll and the revolving scroll;   an intake chamber provided on an outer circumferential side of the fixed scroll;   a discharge port provided in a central part of the fixed scroll;   a muffler provided to cover the discharge port at an upper part of the fixed scroll; and   a heat-insulating member provided between the fixed scroll and the muffler,   wherein after a refrigerant gas taken into the intake chamber is compressed by the revolving scroll revolving and the compression chamber moving while changing a volume of the compressor, the refrigerant gas is discharged from the discharge port,   the refrigerant gas discharged from the discharge port is discharged into a muffler space formed by the muffler, and   the heat-insulating member includes
 a heat-insulating member discharge port provided in a portion facing the discharge port, 
 a lead valve provided on a surface, of the heat-insulating member, on a side opposite to a side facing the fixed scroll, and 
 a recess provided on the surface, of the heat-insulating member, facing the fixed scroll and provided in a 360-degree area in a circumferential direction facing the intake chamber. 
   
     
     
         2 . The compressor according to  claim 1 , wherein in the heat-insulating member, at least one of a rim of the heat-insulating member discharge port provided corresponding to the discharge port and an opening edge of the recess has a protruding shape most protruding toward a side of the fixed scroll. 
     
     
         3 . The compressor according to  claim 1 , wherein a portion close to the heat-insulating member discharge port of the heat-insulating member is fixed to the fixed scroll by a bolt. 
     
     
         4 . The compressor according to  claim 1 , wherein the heat-insulating member is formed of a porous material such as sintered metal. 
     
     
         5 . The compressor according to  claim 1 , wherein a plurality of plates is laminated to form the heat-insulating member. 
     
     
         6 . The compressor according to  claim 5 , wherein the plurality of plates includes plates having the recess.
