Abstract

resumo patente de invenção: "sistema hidráulico com filtro de retorno/sucção". a presente invenção refere-se a um sistema hidráulico, preferencialmente, para pilotar e atuar uma bomba com dois cilindros de matéria espessa. o sistema hidráulico compreende um tanque (68) para receber óleo hidráulico, um circuito primário que tem pelo menos um consumidor hidráulico (ah, mh) que tem pelo menos uma bomba primária (36, 38, 61, 70) que é carregada com óleo hidráulico através de uma primeira linha de sucção (42) e é conectado no lado de saída a pelo menos uma primeira linha de retorno e que tem um filtro de retorno/sucção (40) o qual se comunica com a primeira linha de sucção (42) no lado de saída e é carregado no lado de entrada com óleo de retorno a partir de pelo menos uma linha de retorno. uma característica especial da invenção consiste no fato de que a primeira linha de sucção (42) se comunica com o tanque (68) através de uma linha de sucção de reposição separada (86) e de um filtro de sucção (66) em que uma válvula de reposição de sucção (88), a qual é pré-carregada na direção ao filtro de sucção (66), está disposta na linha de sucção de reposição (86). 20854380v1
