Abstract

A seal structure used in a compressor has a first member, a second member and a seal member with a rigidity. The first member has a surface in a first shape. The first shape has at least a first contacting portion. The second member has a surface in a second shape. The second shape has at least a second contacting portion. The first shape and the second shape are complementary with each other. The seal member has a first seal surface and a second seal surface. The seal member is located between the first contacting portion and the second contacting portion. The seal member has a sufficient area to cover at least the first contacting portion and the second contacting portion. The seal member is press-contacted and correspondingly deformed by the first contacting portion and the second contacting portion, thereby creating a seal between the first member and the second member.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A seal structure used in a compressor comprising: 
 a first member having a surface in a first shape having at least a first contacting portion;    a second member having a surface in a second shape having at least a second contacting portion, the first shape and the second shape being complementary with each other; and    a seal member with a rigidity having a first seal surface and a second seal surface, said seal member being located between said first contacting portion and said second contacting portion, said seal member having a sufficient area to cover at least the first contacting portion and the second contacting portion, said seal member being press-contacted and correspondingly deformed by the first contacting portion and the second contacting portion, thereby creating a seal between the first member and the second member.    
     
     
         2 . The seal structure according to  claim 1  wherein the first shape is a protrusion and the second shape is a recess to receive the protrusion.  
     
     
         3 . The seal structure according to  claim 2  wherein the protrusion and the recess are square.  
     
     
         4 . The seal structure according to  claim 2  wherein the protrusion and the recess are triangular.  
     
     
         5 . The seal structure according to  claim 2  wherein the protrusion and the recess are circular.  
     
     
         6 . The seal structure according to  claim 1  wherein the first shape is a protrusion, and wherein the second shape is an indentation to receive the protrusion.  
     
     
         7 . The seal structure according to  claim 2  wherein thickness of said seal member is larger than height of the protrusion.  
     
     
         8 . The seal structure according to  claim 6  wherein thickness of said seal member is larger than height of the protrusion, the height of the protrusion being substantially equal to depth of the indentation.  
     
     
         9 . The seal structure according to  claim 1  wherein said first member and said second member are respectively a swash plate housing and a cylinder block.  
     
     
         10 . The seal structure according to  claim 1  wherein said seal member has a rigid base plate and rubber seal layers on the rigid base plate.  
     
     
         11 . The seal structure according to  claim 1  wherein said seal member is flat.  
     
     
         12 . The seal structure according to  claim 1  wherein said seal member is a valve plate.  
     
     
         13 . The seal structure according to  claim 1  wherein the first contacting portion, the second contacting portion and said seal member are formed in a closed shape.  
     
     
         14 . A seal structure used in a compressor comprising: 
 a first member having an annular first contacting portion;    a second member having an annular second contacting portion; and    an annular seal member with a predetermined range of rigidity having a first seal surface for contacting the first contacting portion and a second seal surface for contacting the second contacting portion, wherein said annular seal member is press-contacted and deformed by the first contacting portion and the second contacting portion, whereby said annular seal member creates a seal between said first member and said second member.    
     
     
         15 . The seal structure according to  claim 14  wherein the first contacting portion is an edge of a protrusion and the second contacting portion is an edge of a recess.  
     
     
         16 . The seal structure according to  claim 15  wherein the protrusion is in a square shape and the recess is in a square shape to receive the protrusion.  
     
     
         17 . The seal structure according to  claim 15  wherein the protrusion is in a triangular shape and the recess is in a triangular shape to receive the protrusion.  
     
     
         18 . The seal structure according to  claim 15  wherein the protrusion is in a circular shape and the recess is in a circular shape to receive the protrusion.  
     
     
         19 . The seal structure according to  claim 15  wherein the recess is in an indent shape to receive the protrusion.
