Abstract

Il dispositivo opera secondo il principio dello spostamento, cioè sono previsti almeno due sistemi di spostamento disposti in uno spazio operativo comune e rispettivamente in spazi operativi intercomunicanti, accoppiati in senso motore fra loro tramite un mezzo di trasmissione di pressione. Come mezzo di trasmissione di pressione è disposto, secondo l'invenzione, un materiale elastomerico almeno in corrispondenza di un sistema di spostamento.
