Abstract

"DISPOSIçAO DE VáLVULA HIDRáULICA". A invenção refere-se a uma disposição de válvula hidráulica (1) com uma disposição de conexão de suprimento compreendendo uma conexão de alta pressão (P) e uma conexão de baixa pressão (T), uma disposição de conexão de trabalho compreendendo duas conexões de trabalho (A, B), que podem ser conectadas a um motor (4), uma disposição de válvula direcional (5) localizada entre a disposição de conexão de suprimento (P, T) e a disposição de conexão de trabalho (A, B), e uma válvula de compensação (15) acionada em uma primeira direção de ativação por uma pressão em uma primeira câmara de pressão (33), que é conectada a um tubo de sensor de carga (LS), e, se necessário, por uma mola (32), e em uma segunda direção de ativação oposta à primeira direção de ativação por uma pressão a jusante da disposição de válvula direcional (5), a dita pressão agindo em uma segunda câmara de pressão (34), a válvula de compensação (15) possuindo uma entrada (14) e uma saída (19). Em relação a uma válvula pós-compensada, se busca ajustar as pressões de carga nas conexões de trabalho (A, B) dependendo da direção. Para essa finalidade, cada conexão de trabalho (A, B) é conectada a um sistema de controle, que amplifica o efeito da pressão na primeira câmara de pressão (33) na válvula de compensação (15) dependendo de uma pressão que governa a conexão de rede (A, B).
