Abstract

Abstract PURPOSE: To reduce the diameter of a scroll member per unit of volume by designing the starting line of the internal curve of a scroll member in the shape of an arc, thereby enabling the starting line to be located adjacently to the center of a scroll. CONSTITUTION: A curved line DA extending from a starting point D of an internal involute curved line to a curved line A of an external involute is an arc, having no meeting point with a path of a tip A' of another scroll lap. The path meets a curved line of the internal involute at the point D, sweeping a circle whose radius is equal to a shifted distance C e of a crank pin 2 c . Locations of the starting points D, A adjacent to the center of a scroll provide no interaction of the lap tips A, A' so that a hydraulic machine of less coiled times and a shorter diameter may be obtained.
