Abstract
A fluid and/or gas treatment unit containing a dynamic rotating assembly for passage of a fluid and/or gas therethrough comprises a housing having a generally cylindrical body and end walls, and a generally cylindrical member rotatable in the chamber and having a peripheral wall and end surfaces. A shaft extends coaxially through coaxial apertures in the housing end walls, and through a coaxial passage in the rotatable member with which it is engaged to rotate as a unitary assembly. Adjacent the inner surface of each end wall of the housing are, seriatim, a resiliently deflectable biasing element, a generally circular wear plate and a resiliently compressible, generally circular sealing member between the wear plate and the cylindrical member and rotatable therewith. A generally circular bearing member extends about the generally circular sealing member and the cylindrical member and is rotatable therewith. The wear plates bear against the bearing members and the sealing members, and the sealing members are resiliently compressed between the cylindrical member and the wear plates to a controlled extent.
