1. An annular axially resilient coiled spring seal comprising:

  • a plurality of coils canted along a centerline thereof;

    back angle means for both defining the disposition of a trailing portion of each coil with respect to a line normal to the centerline and for determining the load-deflection characteristics of the garter-type axially resilient coiled spring;

    front angle means for defining the disposition of a leading portion of each coil with respect to the normal line, said front angle means being greater than said back angle means;

    said coils being interconnected in a manner forming a garter-type axially resilient coiled spring; and

    annular seal means for non-invasively supporting the garter-type axially resilient coiled spring in a preselected orientation for controlling the resilient characteristics of the annular axially resilient coiled spring.
