Compressor

Abstract

Compressor including a chamber having a muffler room therein for introducing refrigerant compressed at a compression part, a cover on top of the chamber for closing an upper part of the muffler room, and a discharge muffler including a first coating gasket having a base part with coated layers on upper and lower surfaces for sealing between the chamber and the cover, thereby reducing noise and simplifying assembly.

1 . A compressor comprising a valve assembly, comprising: 
 a suction plate in front of a cylinder for compressing refrigerant therein, having a suction valve and a discharge passage;    a valve plate in front of the suction plate, having a suction hole and a discharge hole;    a discharge plate in front of the valve plate, having a discharge valve for selective opening of the discharge hole, and a suction passage;    a head cover in front of the discharge plate, for isolating the refrigerant being drawn, from the refrigerant being discharged; and    a second coating gasket between the discharge plate and the head cover, having a retainer for regulating opening of the discharge plate and a suction passage in one side part thereof.    
   
   
       2 . The compressor as claimed in  claim 1 , wherein the second coating gasket comprises: 
 a base part of metal; and    coated layers on outside surfaces of the base part.    
   
   
       3 . The compressor as claimed in  claim 2 , wherein the metal is steel.  
   
   
       4 . The compressor as claimed in  claim 2 , wherein the coated layers are formed of elastic rubber.  
   
   
       5 . The compressor as claimed in  claim 1 , wherein the second coating gasket has an opening in an inside part, and wherein the retainer is formed across the opening.  
   
   
       6 . The compressor as claimed in  claim 5 , wherein the retainer is bent at opposite side parts to project toward the head cover.  
   
   
       7 . The compressor as claimed in  claim 5 , wherein the retainer is formed at a position in contact with a front surface of the discharge valve.  
   
   
       8 . The compressor as claimed in  claim 7 , wherein the retainer deforms elastically in a forward direction of the second coating gasket when the discharge valve is opened.  
   
   
       9 . The compressor as claimed in  claim 7 , wherein the retainer restores from the elastic deformation after discharge of refrigerant is finished, to push the discharge valve closed.  
   
   
       10 . The compressor as claimed in  claim 1 , wherein the suction valve is formed as one unit with the suction plate.  
   
   
       11 . The compressor as claimed in  claim 1 , wherein the discharge valve is formed as one unit with the discharge plate.  
   
   
       12 . The compressor as claimed in  claim 1 , wherein the suction valve is opened as the suction valve is pushed backward of the suction plate by a pressure of the refrigerant while movement of the suction valve in a forward direction of the suction plate is held.  
   
   
       13 . The compressor as claimed in  claim 1 , wherein the discharge valve is opened as the discharge valve is pushed forward of the discharge plate by a pressure of the refrigerant while movement of the discharge valve in a backward direction of the discharge plate is held.  
   
   
       14 . The compressor as claimed in  claim 1 , wherein respective plates and the head cover have holes at four corners thereof, and bolts are inserted in the holes, respectively.  
   
   
       15 . The compressor as claimed in  claim 14 , wherein the bolts have ends fastened to a front surface of the cylinder, and wherein the plates and the head cover are clamped between the heads of the bolts, and the front surface of the cylinder.
