FIELD: mechanical engineering.
SUBSTANCE: device comprises deforming cylindrical spring that is rolled into a ring and is fit on the regular polyhedron with interference. The number of tops of the regular polyhedron is equal to the number of turns of the spring. The regular polyhedron is secured to the mandrel that is made for permitting rotation. The spring is freely mounted in the separator and is locked against rotation with respect to its longitudinal axis.
EFFECT: expanded functional capabilities.
