For a scroll fluid machine with an arbitrary number of scroll wraps on its individual scroll, the phase difference between adjacent scroll profiles on one scroll is defined as the characteristic angle of the scroll. Based on general profile theory, a scroll pitch line is defined as of A-type with which the outer profile of orbiting scroll and the inner profile of fixed scroll can be formed. Another scroll pitch line is defined as B-type with which the inner profile of orbiting scroll and the outer profile of fixed scroll can be formed. The scroll compression chambers corresponding to the pitch lines of A-type and that of B-type are defined as compression chambers of A-series and B-series, respectively. Then the general geometrical model of scroll compression chamber is set up. It can demonstrate the deforming, opening, and vanishing process of all scroll chambers.
