Abstract
A scroll compressor includes a casing, an electric motor and a compressor unit housed in the casing and the compressor unit comprises a movable member having a first scroll blade driven eccentrically by the electric motor and a structural member having a second scroll blade encasing the movable member so that the first scroll blade revolves around a central axis of the compressor with a predetermined radius of revolution, while the first blade is maintained in sliding contact with the second blade. The two scroll blades are formed by drawing a series of semicircles alternately around a first point and a second point spaced apart from the first point. An internal end portion of the first and second scroll blades includes a planar surface disposed perpendicular to a line interconnecting the first and second point.
