ABSTRACT:
A scroll type fluid displacement apparatus including an orbiting scroll and a fixed scroll, each having an end plate and a spiral element is disclosed. The spiral elements interfit at an angular and radial offset to form a plurality of line contacts between the spiral curved surfaces to define at least one pair of fluid pockets. A driving mechanism is operatively connected to the orbiting scroll for orbiting the orbiting scroll relative to the fixed scroll while preventing rotation of the orbiting scroll. This changes the volume of the fluid pockets. A plurality of threaded holes are formed through the end plate of the fixed scroll for attaching the fixed scroll to the inner end surface of projecting portions of the compressor housing. The projecting portions extend toward the fixed scroll and have threaded holes formed therein. A bolt is screwed through the fixed scroll holes and into the holes in the projecting portions to attach the fixed scroll to the housing.
