Abstract: A scroll type apparatus for fluid displacement is disclosed. In one embodiment, the apparatus includes an adjustment mechanism capable of being adjusted after assembly of the apparatus to close an axial gap between scroll members and account for manufacturing tolerances in apparatus components. In another embodiment, the apparatus includes an orbital scroll of two portions, with a supporting portion surrounding an eccentric bearing of higher density than that of a scroll portion. The center of mass of the orbital scroll is thus moved towards the eccentric bearing to reduce torquing of the scroll as it orbits. In a further embodiment, the apparatus includes an orbital scroll having two portions, a supporting portion surrounding an eccentric bearing having a lower coefficient of thermal expansion than that of a scroll portion, to reduce thermal expansion of the supporting portion, reducing misalignment of the eccentric orbital scroll on the bearing.
