Abstract
A base plate 41 of a movable scroll member 4 has, at its outer periphery, a section 44 with no scroll wall, while a scroll wall 22 of a stationary scroll member 2 has a section 24 for connecting to an outer cylindrical shell 22. These sections 44 and 24 make a relative lateral slide movement during an orbital movement of the movable scroll member 4 with respect to the stationary scroll member 2. These sections 44 and 24 have axially faced inner and outer edges 44-1 and 24-1, over which the relative lateral movement occurs. These inner and outer edges 44-1 and 24-1 are bevelled, the bevelling being such that any skewed movement of the movable scroll member with respect to the stationary scroll member does not cause locally increased contact pressure, thereby preventing galling as well as seizing.
