Abstract

"CILINDRO COMPACTO PRINCIPAL EM TANDEM COM SAìDA PRIMáRIA DE DESVIO", compreendendo um cilindro hidráulico principal em tandem, consistindo principalmente de um corpo (1) transpassado com um furo, primeira e segunda entradas (2s, 2b) para fluido hidráulico a baixa pressão, um êmbolo primário (3) e um êmbolo secundário (4) que desliza respectivamente na primeira e segunda seções longitudinais (S1, S2), uma câmara primária de presão (5), uma câmara secundária de pressão (6), primeiro e segundo copos de vedação a jusante e a montante (91A, 91B, 92A, 92B), primeiro e segundo dutos de reabastecimento (21, 22) e primeiro e segundo orifícios de saída (41, 2 42) para o fluido hidráulico pressurizado). De acordo com a invenção, os êmbolos primário e secundário (3, 4) são guiados pela parede (100) do furo, com o qual elas estão em contato, e o corpo (1) também é transpassado com uma primeira passagem longitudinal (51) que liga o primeiro copo a jusante (91b), o segundo copo a montante (92a) e o primeiro orifício de saída (41) e comunicando-se com a câmara primária de pressão (5) via primeira passagem radial (61) localizada entre a primeira e segunda seções longitudinais (S1, S2).
