Abstract
A coiled spring includes a plurality of coils with each of the coils being interconnected with one another in a spaced-apart relationship and disposed in a preselected acute angle with the centerline of the coil spring for causing the coil spring to exert a constant force in a loading direction approximately normal to the centerline of the coiled spring in response to a deflection of the coil spring along the loading direction. When placed in an operative relationship with a sealing material, the resulting coil spring seal enables positive sealing between cooperating parts to prevent passage of fluid therepast, despite small changes in the spacing between the parts which may change due to eccentricity and part dimension, wear, temperature, or pressure effects.
