A scroll member is provided for use in scroll-type apparatus. It is formed of a separate end plate having an involutely configured groove in the face thereof and a separate involute wrap which is seated in the groove. The seating of the wrap in the groove may be such as to permit it to undergo small axial and radial excursions within the groove to impart compliance/sealing characteristics to the scroll member. Alternatively, the wrap may be rigidly mounted in the groove and, if desired, separate compliance/sealing means provided for the wrap. The construction of scroll members according to this invention achieves a marked decrease in cost of the scroll members and of scroll-type apparatus incorporating them. |
