two snails be co rotating device for compression / expansion difluidi with improved stability to the nutation.

摘要

in a device for winding having two snails be co rotating of leech which is interfogliano fixed to plate end revolving around axes parallel.not aligned to produce a relative orbital motion, a mass fixed to at least one of the snails be to improve the stability of the nutation of the organ in the cochlea.preferably,the means of reducing nutation include a mass fixed to a plate side of the spiral body to induce a dynamic imbalance during the rotation of the spiral body.creating a moment of balance and moderation, enough to compensate for the moment induced by the pressure variation of fluid in various chambers of compression during the rotation of the org.anus in the cochlea.
