Abstract
A two-piece scroll member, for use in scroll apparatus, is fabricated by seating a separately formed involute wrap in an involute channel cut in the end plate. The channel has at least one reentrant groove and the surface of the wrap is configured to engage the groove. Locking means are coined into the groove to rigidly affix the wrap to the end plate.
