Apparatus for absorbing vibration of compressor

Abstract

An apparatus for absorbing vibration of a compressor includes: an elastic body mounted at an outer surface of a compressor case and elastically deformed when vibration is generated at a compressor; and a mass body connected to the elastic body, resonating with the compressor, for absorbing vibration of the compressor. Accordingly, vibration of the compressor is reduced so that noise and reliability degradation of a component due to the vibration can be reduced.

1 . An apparatus for absorbing vibration of a compressor comprising: 
 an elastic body mounted at an outer surface of a compressor case and elastically deformed when vibration is generated at a compressor; and    at least one mass body connected to the elastic body, resonating with the compressor, for absorbing vibration of the compressor.    
   
   
       2 . The apparatus of  claim 1 , wherein a plurality of the elastic bodies are disposed at an outer surface of the case of the compressor at regular intervals in a circumferential direction.  
   
   
       3 . The apparatus of  claim 1 , wherein the elastic body is a plate spring having one end connected to an outer surface of the compressor case and the other end connected to the mass body.  
   
   
       4 . The apparatus of  claim 2 , wherein the elastic body is a coil spring having one end connected to an outer surface of the compressor case and the other end connected to the mass body.  
   
   
       5 . The apparatus of  claim 1 , wherein the mass body is formed in a ring shape and disposed in a circumferential direction of the compressor case.  
   
   
       6 . The apparatus of  claim 1 , wherein the mass of the mass body is about 5˜25% of the mass of the compressor main body.  
   
   
       7 . The apparatus of  claim 2 , further comprising a fixing member mounted at an outer circumferential surface of the compressor case, for fixing the elastic body to the compressor case.  
   
   
       8 . The apparatus of  claim 7 , wherein the fixing member is formed in a ring shape and insertedly coupled to the outer surface of the compressor case in a circumferential direction.  
   
   
       9 . The apparatus of  claim 7 , wherein the elastic bodies are integrally formed at an outer surface of the fixing member at regular intervals.  
   
   
       10 . The apparatus of  claim 7 , further comprising a stopper for preventing the fixing member which is insertedly coupled to the compressor case from being slipped out.  
   
   
       11 . The apparatus of  claim 10 , wherein the stopper is outwardly protruded from an circumferential surface of the compressor case.  
   
   
       12 . The apparatus of  claim 9 , wherein the elastic body is a coil spring mounted at an upper surface of the compressor case.  
   
   
       13 . The apparatus of  claim 1 , wherein the elastic body is a coil spring mounted at an upper surface of the compressor case.  
   
   
       14 . The apparatus of  claim 13 , wherein the mass body is formed in a plate shape and mounted at an upper surface of the elastic body.
