Hermetic Compressor

Abstract

It is disclosed a hermetic compressor, provided with at least one fluid expansion chamber, whose useful volume is narrowly defined between a section of one of the faces (inner or outer) of the airtight housing of the compressor and at least one wall section adjacently attached to one of the faces of the airtight housing of the compressor.

1 . Hermetic compressor, comprising:
 an airtight housing;   at least one reciprocating compression mechanism (not illustrated) arranged within the airtight housing; and   at least one fluid expansion chamber;   said hermetic compressor being especially characterized in that said fluid expansion chamber is formed between one of the faces of the airtight housing and the inner face of a first modular body is hermetically attached to one of the faces of the airtight housing; and   said fluid expansion chamber comprises at least one inlet path and at least one outlet path.   
     
     
         2 . Hermetic compressor, according to  claim 1 , characterized in that the fluid expansion chamber comprises a discharge fluid expansion chamber. 
     
     
         3 . Hermetic compressor, according to  claim 1 , characterized in that the fluid expansion chamber comprises a suction fluid expansion chamber. 
     
     
         4 . Hermetic compressor, according to  claim 1 , characterized in that the fluid expansion chamber is external, being formed between the outer face of the airtight housing and the inner face of a first modular body hermetically attached to the outer face of the airtight housing. 
     
     
         5 . Hermetic compressor, according to  claim 1 , characterized in that the fluid expansion chamber is internal, being formed between the inner face of the airtight housing and the inner face of a first modular body hermetically attached to the inner face of the airtight housing. 
     
     
         6 . Hermetic compressor, according to  claim 1 , characterized in that the inlet path and the outlet path of the fluid expansion chamber are fluidly aligned. 
     
     
         7 . Hermetic compressor, according to  claim 1 , characterized in that the inlet path and the outlet path of the fluid expansion chamber are fluidly misaligned. 
     
     
         8 . Hermetic compressor, according to  claim 1 , characterized in that it further comprises at least one second fluid expansion chamber fluidly connected, in series, to the fluid expansion chamber. 
     
     
         9 . Hermetic compressor, according to  claim 8 , characterized in that said second fluid expansion chamber is internal, being arranged within the airtight housing. 
     
     
         10 . Hermetic compressor, according to  claim 9 , characterized in that said second fluid expansion chamber is formed, at least partially, between the inner face of the airtight housing and the inner face of a second modular body. 
     
     
         11 . Hermetic compressor, according to  claim 9 , characterized in that said second fluid expansion chamber is formed, at least partially, between the outer face of the first modular body and the inner face of a second modular body. 
     
     
         12 . Hermetic compressor, according to  claim 8 , characterized in that said second fluid expansion chamber is external, being arranged on the outside of the airtight housing. 
     
     
         13 . Hermetic compressor, according to  claim 12 , characterized in that said second fluid expansion chamber is formed, at least partially, between the outer face of the airtight housing and the inner face of a second modular body. 
     
     
         14 . Hermetic compressor, according to  claim 12 , characterized in that said second fluid expansion chamber is formed, at least partially, between the outer face of the first modular body and the inner face of a second modular body.
