ABSTRACT:
An involute and tip seal for use in a positive fluid displacement apparatus of the scroll type. A scroll machine wrap element of general spiral configuration about an axis includes a radially inner and outer flank surface terminating in a tip. In the tip, a groove is formed which runs in the longitudinal direction of the wrap element and substantially conforms to its spiral shape. A plurality of material strips, generally coaligned in parallel side-by-side relationship, are disposed within the spiral groove of the involute wrap. One or more of the strips includes a plurality of notches along at least one of the two axial edges. These notches, in conjunction with one or more of the adjacent strips and a flat surface against which the notched edge abuts, define a plurality of labyrinth pockets longitudinally spaced along the strips. The labyrinth surface improves both longitudinal and transverse fluid sealing of the involute tip seal.
