Abstract

a presente invenção se refere a um cilindro hidráulico de dupla ação (10) que compreende uma primeira carcaça do cilindro (14) e um pistão (26) conduzido na primeira carcaça do cilindro (14), sendo que, na primeira carcaça do cilindro (14) estão previstas uma primeira câmara de pressão (36) e uma segunda câmara de pressão (38), as quais estão separadas entre si através do pistão (26). uma primeira ligação (32) serve pelo menos para a condução de um líquido hidráulico para a primeira câmara de pressão (36), e uma segunda ligação (34) serve pelo menos para a condução de um líquido hidráulico para a segunda câmara de pressão (38). além disso, uma segunda carcaça do cilindro (16) envolve a primeira carcaça do cilindro (14) pelo menos em uma seção (41). a primeira ligação (32) e a segunda ligação (34) estão dispostas em uma extremidade do cilindro hidráulico de dupla ação (10) afastada da segunda câmara de pressão (38). a segunda câmara de pressão (38) pode ser pressurizada com o líquido hidráulico através da seção (41), na qual a segunda carcaça do cilindro (16) envolve a primeira carcaça do cilindro (14).
