Abstract

ACIONADOR TELESCàPICO. A invenção refere-se a um acionador telescópico compreendendo um corpo (1) definindo uma cavidade cilíndrica do eixo geométrico longitudinal (X); uma haste (3) montada para deslizar de modo telescópico no cilindro ao longo do dito eixo geométrico; uma porca (7) presa na haste; um parafuso de avanço (4) montado no cilindro para se estender ao longo e girar ao redor do dito eixo geométrico (X) e colaborar com a porca em tal maneira que a rotação do parafuso de avanço causa um movimento telescópico da haste no cilindro; dispositivos (8,9,10) para impelir a rotação do parafuso de avanço. De acordo com a invenção, a porca é montada na haste para se axialmente
