Abstract

"ATUADOR". A invenção diz respeito a um atuador que compreende um corpo (1, 2, 3) com uma cavidade cilíndrica, e uma haste (4) que estende-se através de uma extremidade (3) da cavidade, sendo preso a um pistão (5) montado de forma a deslizar axialmente no interior da cavidade, de maneira a definir nela duas câmaras hidráulicas (S, R), o atuador incluindo dispositivo adicional para estender a haste, que compreende: dispositivo para impedir que a haste (4) gire em relação ao corpo (1, 2, 3) do atuador; uma porca (7) presa rigidamente na haste (4); um parafuso (8) que estende-se axialmente ao interior da cavidade e que coopera com a porca (7); um eixo de acionamento (9) que estende-se axialmente no interior da cavidade e que é livre para girar, o parafuso (8) sendo montado de forma a deslizar sem rotação ao longo do eixo; e dispositivo de acionamento rotativo (13) para acionar o eixo de acionamento (9).
