Abstract
válvula hidráulica com limitador de pressão. um conjunto de seções de válvula 10 inclui uma seção de entrada 12, uma seção de saída 14, uma seção de trabalho 16, e uma seção de trabalho 18. a seção de trabalho 16 é uma seção de trabalho de pressão compensada convencional. a seção de trabalho 18 inclui uma válvula de controle direcional 21, uma válvula de compensação de pressão 50, e uma válvula limitadora de pressão 52. as válvulas 50 e 52 são de construção integral, de tal modo que cada uma é uma parte essencial para completar a outra. a válvula de compensação de pressão 50 inclui um carretel compensador de pressão 60 móvel entre uma posição aberta (figuras 2 e 5) e uma posição de fechada (figuras 4 e 6), em resposta a um diferencial de pressão através do carretel. a válvula limitadora de pressão 52 inclui um carretel limitador de pressão 76 que se move para uma posição aberta para mudar o diferencial de pressão e fecha a válvula de compensação de pressão quando a pressão limite selecionado é alcançada.
