<p>A scroll type compressing apparatus includes stationary and movable scroll wraps each having a strengthened inner end wall surface portion, and minimizes an excessive compression of a gaseous fluid in a compressing cell defined by the scroll wraps. The inner end wall surface portion is formed by an arcuate surface and a straight line surface tangent to an involute generating base circle from a line contacting point of one of the scroll wraps at which the inner end portion of the other scroll wrap contacts the inner wall surface of one of the scroll wraps when the gaseous fluid in the compressing cell is compressed at a prescribed target compression ratio.</p> |
