First Claim
Patent Images
1. A radially resilient canted coiled spring comprising:
- a plurality of coil means, interconnected and canted along a centerline thereof, for causing the coiled spring to exert a generally constant force over a preselected range of deflection of the coiled spring in response to radial loading;
back angle means for defining the disposition of a trailing portion of each coil with respect to a line normal to the centerline;
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; and
means, orienting said plurality of coil means at a turn angle, for controlling the magnitude of the generally constant force within the preselected range of deflection, said turn angle being greater than zero degrees and less than 90 degrees.

Abstract
A radially resilient canted coiled springs includes a plurality of coils canted along a centerline thereof with each coil having a trailing portion and a leading portion. The disposition of the trailing portion is defined by a back angle between the trailing portion and a line normal to the centerline and the disposition of the leading portion is defined by a front angle between the leading portion and a normal line. Specific resilient performance, or load-deflection characteristics of the radially resilient canted coiled springs is determined by controlling a turn angle of the coil spring.

9. A radially resilient canted coiled spring seal comprising:
-
a plurality of coil means, interconnected and canted along a centerline thereof, for causing the coiled spring to exert a generally constant force over a preselected range of deflection of the coiled spring in response to radial loading; back angle means for defining the disposition of a trailing portion of each coil with respect to a line normal to the centerline; 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; and annular seal means for non-invasively supporting the radially resilient canted coiled spring in an orientation for controlling the magnitude of the generally constant force within the preselected range of deflection, said orientation being defined by a turn angle, said turn angle being greater than zero degrees and less than 90 degrees. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
