Abstract
This invention provides a scroll type compressor employing an Oldham coupling producing little vibration or noise and in which components thereof are easy to produce by means of a lathe. The Oldham coupling blocks a rotation of a movable scroll member 4. A direction of a reciprocation of the Oldham coupling 16 coincides with a minor axis of an elliptic circulating orbit of the movable scroll member 4. When a total mass of the movable scroll member 4 and parts circulating elliptically together therewith is ma, a mass of an Oldham ring 16 is mb, a radius of a minor axis of an elliptic circulating orbit is R.sub.Y and a radius of a major axis of the elliptic circulating orbit is R.sub.X, a relation of R.sub.X =(1+mb/ma)R.sub.Y is established.
