Abstract

"SISTEMA DE VáLVULA HIDRáULICA". A presente invenção refere-se a um sistema de válvula hidráulica com um conjunto de conexão de alimentação, compreendendo uma conexão de entrada e uma conexão de saída, um conjunto de conexão de trabalho tendo pelo menos uma conexão de trabalho, uma válvula de controle localizada entre o conjunto de conexão de alimentação e compreendendo uma corrediça, e pelo uma válvula de detenção entre a válvula de controle e uma conexão de trabalho, cuja válvula de detenção pode ser aberta por uma válvula piloto mecanicamente ativada tendo um elemento de comando cooperando com um elemento de válvula, uma superfície de controle da corrediça atuando sobre o elemento de comando. é contemplado simplificar a atuação de um sistema de válvula deste tipo. Para esta finalidade, na direção de deslocamento (28) da corrediça (4), o elemento de comando (24) é localizado contíguo à corrediça (4) e pode ser defletido transversalmente à direção de deslocamento (28) da corrediça (4).
