Abstract

"ARRANJO DE VáLVULA HIDRáULICA". A presente invenção refere-se a um arranjo de válvula hidráulica (1) com pelo menos dois módulos de válvula (2 - 6), cada um tendo um arranjo de canal de suprimento com um canal de alta pressão (9) e um canal de baixa pressão (15), um arranjo de conexão de trabalho com pelo menos uma conexão de trabalho (A, B), um arranjo de válvula direcional (16) entre o arranjo de canal de suprimento (9, 15) e o arranjo de conexão de trabalho (A, B) e um arranjo de compensação (19), o qual é atuado por uma pressão em um arranjo de detecção de carga. é divisado aumentar o número de possibilidades de controle. Para esta finalidade, o arranjo de detecção de carga de pelo menos um módulo de válvula (2 - 6) tem um arranjo de influência de pressão (25 - 29) que difere de um arranjo de influência de pressão (25 - 29) de um arranjo de detecção de carga de um outro módulo de válvula (2 - 6).
