Patent ID: 7905715

Claim:
A scroll compressor in which a scroll fixed lap rising from a fixed mirror plate of a fixed scroll part and a scroll orbiting lap rising from an orbiting mirror plate of an orbiting scroll part are meshed with each other to form compression chambers therebetween, said orbiting scroll part is allowed to orbit in a circular orbit while restraining said orbiting scroll part from rotating by a rotation-restraint mechanism, a refrigerant is sucked, compressed and discharged while continuously varying a capacity of said compression chamber, wherein a first gap in a thrust direction between teeth bottoms of said fixed mirror plate and teeth tips of said orbiting lap and a second gap in a thrust direction between teeth bottoms of said orbiting mirror plate and teeth tips of said fixed lap are formed into such shapes that said first and second gaps are gradually increased from an outer peripheral side to an inner peripheral side of said scroll compressor, and said first gap is made greater than said second gap, and teeth bottoms of said orbiting mirror plate, teeth tips of said fixed lap and outer peripheral thrust surface come into contact before teeth bottoms of said fixed mirror plate and teeth tips of said orbiting lap come into contact and contact pressure of teeth tips of said fixed lap and teeth bottoms of said orbiting mirror plate is equally maintained.
