Abstract

A presente invenção trata de um atuador hidráulico submarino com retorno por mola, sendo que dita mola está exposta diretamente em contato com a água do mar, sendo constituída de material inerte a corrosão e de construção peculiar. Dita mola é montada em um batente móvel (3) acoplado por meios especiais de fixação à haste do atuador (5) e que está em contato deslizante com um prolongamento estabilizador (4) da haste do atuador (5) através de dois ou mais rasgos guias (20).
