Reciprocating compressor

Abstract

The invention concerns a reciprocating compressor, particularly for refrigerants, with a cylinder housing, in which at least one cylinder chamber is arranged, and a cylinder head, which delimits the cylinder chamber and has a valve plate with a suction valve arrangement that is connected with a suction chamber, and with a pressure valve arrangement, which is connected with a pressure chamber that is separated from the suction chamber. It is endeavoured to improve the sealing between the suction chamber and the pressure chamber. For this purpose, the valve plate has, on the side facing away from the cylinder chamber, a projection, which separates the suction chamber from the pressure chamber.

1 - 10 . (canceled)  
   
   
       11 . A reciprocating compressor, particularly for refrigerants, with a cylinder housing, in which at least one cylinder chamber is arranged, and a cylinder head, which delimits the cylinder chamber and has a valve plate with a suction valve arrangement that is connected with a suction chamber, and with a pressure valve arrangement, which is connected with a pressure chamber that is separated from the suction chamber, wherein the side facing away from the cylinder chamber, the valve plate has a projection, which separates the suction chamber from the pressure chamber.  
   
   
       12 . A compressor according to  claim 11 , wherein the thickness (d) of the valve plate is smaller in the area of the pressure valve arrangement than in the area of the suction valve arrangement.  
   
   
       13 . A compressor according to  claim 11 , wherein the pressure valve arrangement has a pressure opening into the pressure chamber, which lies next to the projection.  
   
   
       14 . A compressor according to  claim 11 , wherein at least one of the suction chamber and the pressure chamber are delimited in the circumferential direction by walls, which are formed by projections on the valve plate.  
   
   
       15 . A compressor according to  claim 14 , wherein the cylinder head has a cover, which has, at least on the bottom side facing the valve plate, a plane surface.  
   
   
       16 . A compressor according to  claim 14 , wherein at least the projection separating the suction chamber from the pressure chamber has, on the end turning away from the valve plate, a larger thickness than near the valve plate.  
   
   
       17 . A compressor according to  claim 11 , wherein between the suction chamber and the pressure chamber, the projection forms, at least in sections, a double wall with two wall sections, between which a gas volume is arranged.  
   
   
       18 . A compressor according to  claim 11 , wherein the suction valve arrangement has a suction opening to the suction chamber, which is, at least partly, arranged within the projection between the suction chamber and the pressure chamber.  
   
   
       19 . A compressor according to  claim 11 , wherein the suction valve arrangement is connected with a gas reservoir via a suction path lined with a plastic material.  
   
   
       20 . A compressor according to  claim 19 , wherein the suction path is in the form of a suction muffler.
