Compressor

Abstract

A compressor comprises a housing assembly, a compression mechanism and a sealing member. The housing assembly has a first housing member and a second housing member coupled to each other. The first housing member has an opening end surface. The second housing member has an opening end surface. The compression mechanism is disposed in the first housing member and compresses gas supplied to the compressor. The sealing member includes a first portion and a second portion. The first portion is interposed between the opening end surface of the first housing member and the opening end surface of the second housing member. The second portion of the sealing extends radially inwardly from the first portion to be interposed between the compression mechanism and the second housing member.

1 . A compressor that receives gas from an outer circuit, said compressor comprising: 
 a housing assembly having a first housing member and a second housing member coupled to the first housing member, said first housing member having an opening end surface, said second housing member having an opening end surface;    a compression mechanism disposed in the first housing member, said compression mechanism compressing gas supplied to the compressor, said compressor mechanism has a contact surface; and    a circular sealing member which includes a first portion and a second portion, wherein said first portion is interposed between the opening end surface of the first housing member and the opening end surface of the second housing member, and wherein said second portion extends radially inwardly from the first portion to be interposed between the contact surfaces of the compression mechanism and the second housing member.    
     
     
         2 . A compressor according to  claim 1 , wherein the opening end surface of the first housing member is located on substantially the same plane as the contact surface of the compression mechanism.  
     
     
         3 . A compressor according to  claim 1 , wherein a discharge chamber is defined in the second housing member to receive gas compressed by the compression mechanism.  
     
     
         4 . A compressor according to  claim 1 , wherein the second housing member has an extended edge and the first housing member has an inner shoulder, wherein the extended edge of the second housing member and the inner shoulder of the first housing member clamp the compression mechanism, and wherein the second portion of the sealing member is interposed between the extended edge of the second housing member and the contact surface of the compression mechanism.  
     
     
         5 . A compressor according to  claim 4 , wherein the opening end surface of the second housing member is located on substantially the same plane as the extended edge of the second housing member.  
     
     
         6 . A compressor according to  claim 1 , wherein the compression mechanism is driven by an electric motor which is placed within the first housing member.  
     
     
         7 . A compressor according to  claim 1 , wherein the compression mechanism is a scroll type compression mechanism having a fixed scroll, the fixed scroll being connected to the second housing member so that the discharge chamber is defined within the second housing.  
     
     
         8 . A compressor that receives gas from an outer circuit, said compressor comprising: 
 a housing assembly having a first housing member and a second housing member coupled to the first housing member, said first housing member having a first opening, a first closing wall opposite to the first opening, and an opening end surface; said second housing member having a second opening, a second closing wall opposite to the second opening, and an opening end surface of said first housing member;    a compression mechanism disposed in the first housing member, said compression mechanism compressing gas supplied to the compressor, said compression mechanism has a contact surface;    a discharge chamber defined in the second housing member to receive gas compressed by the compression mechanism; and    a circular sealing member which includes a first portion and a second portion; wherein said first portion is interposed between the opening end surface of said first housing member and the opening end surface of the second housing member, said first housing member and second housing member form a space partitioned by the sealing member; wherein said second portion extends radially inwardly from the first portion to be interposed between the contact surfaces of the compression mechanism and the second housing member.    
     
     
         9 . A compressor according to  claim 8 , wherein the second housing member has an extended edge and the first housing member has an inner shoulder, wherein the extended edge of the second housing member and the inner shoulder of the first housing member clamp the compression mechanism, and wherein the second portion of the sealing member is interposed between the extended edge of the second housing member and the contact surface of the compression mechanism.  
     
     
         10 . A compressor according to  claim 9 , wherein the opening end surface of the second housing member is located on substantially the same plane as the extended edge of the second housing member.  
     
     
         11 . A compressor according to  claim 8 , wherein the compression mechanism is driven by an electric motor which is placed within the first housing member.  
     
     
         12 . A compressor according to  claim 8 , wherein the compression mechanism is a scroll type compression mechanism having a fixed scroll, the fixed scroll being connected to the second housing member so that the discharge chamber is defined within the second housing.  
     
     
         13 . A compressor according to  claim 8 , wherein the opening end surface of the first housing member is located on substantially the same plane as the contact surface of the compression mechanism.
