ABSTRACT:
A fluid scroll machine comprises a fluid mechanism including first and second spiral blades located in a frame to eccentrically rotate and a compression chamber defined by the spiral blades, and an Oldham's coupling movably supported by the frame and including a ring-shaped plate having one side facing the first spiral blade and an axis center, a pair of first projections projected from the one side of the ring-shaped plate, and a pair of second projections projected from the one side of the ring-shaped plate. The first spiral blade includes a pair of first guide passages extended in a same direction as a first radial direction of the ring-shaped plate and into which the first projections are fitted to slide in a first radial direction of the plate. The second spiral blade includes a pair of second guide passages extended in a same direction as a second radial direction of the ring-shaped plate and into which the second projections are fitted to slide in the second radial direction of the plate.
