Abstract
Axial compliance/sealing means are provided for scroll-type apparatus. These means comprise seal elements associated with the involute wraps which are urged by an axial force to make sealing contact with the end plates of the opposing scroll members. The axial force may be pneumatically or mechanically applied and the resulting axial contact is of such a nature as to maintain the integrity of the radial sealing within the apparatus. The use of the axial compliance/sealing means allows the contacting surfaces through which radial sealing is effected to be machined to conventional accuracy, and provides automatic compensation for temperature differentials within the apparatus as well for any uneven wear of the scroll members.
