Abstract

resumo patente de invenção: "cilindro hidráulico com um amortecimento de posição final". a presente invenção refere-se a um cilindro hidráulico (10) com um amortecimento de posição final, incluindo pelo menos um cilindro (11), no qual está disposto pelo menos um êmbolo (12), o qual está conectado com pelo menos uma haste de êmbolo (13) e pode ser movido em direção axial, sendo que o cilindro (11) é subdividido pelo êmbolo (12) em um lado de êmbolo (15) e um lado de haste (16) e o óleo hidráulico necessário para o acionamento do êmbolo (12) é bombeado por uma bomba hidráulica (17), por dutos de entrada e de saída (20, 19), através de aberturas de entrada e de saída previstas no cilindro, cilindro hidráulico este que se caracteriza pelo fato de que ao cilindro (11) é associado um pré-estrangulamento mecânico (23), através do qual, ao ocorrer o deslocamento do êmbolo (12), o óleo hidráulico pode ser descarregado pelo lado de haste (16) através de uma primeira perfuração (24) até que o êmbolo (11), ao se deslocar, feche a primeira perfuração (24) e, consequentemente, o óleo hidráulico é descarregado através de uma segunda perfuração (26), sendo que o pré-estrangulamento mecânico (23), a uma pressão pré-ajustada, força a bomba hidráulica (17) para uma função de corte de pressão regulada eletronicamente, a qual reduz a quantidade transportada do óleo hidráulico e o êmbolo (11) pode ser deslocado, de modo freado, para sua posição final (28).
