Abstract

a presente invenção refere-se a uma válvula limitadora de pressão (10), com uma carcaça de válvula (12) e um pistão de válvula (18) e uma mola de ajuste de limitação de pressão (28), sendo que na carca-ça de válvula (12) está prevista pelo menos uma entrada de válvula (14) e pelo menos uma saída de válvula (16), sendo que o pistão de válvula (18) pode assumir uma posição de abertura (b), na qual a en-trada de válvula (14) e a saída de válvula (16) estão conectadas uma com a outra, e pelo menos uma posição de fecho (d), na qual a entra-da de válvula (14) e a saída de válvula (16) estão separadas uma da outra, sendo que o pistão de válvula (18) apresenta um primeiro anel de pistão (20), com uma superfície de vedação (40) e um segundo anel de pistão (22), sendo que na posição de fecho (d), a superfície de ve-dação (40) do primeiro anel de pistão (20) está hermeticamente puxa-da por tração, contra um ressalto de carcaça (24), por uma força pneumática, que atua no segundo anel de pistão (22) e que está diri-gida contra a força da mola de ajuste de limitação de pressão (28), e sendo que, ainda, está presente no pistão de válvula (18) uma passa-gem pneumática (26), para formação de uma função de segurança, que pode ser vedada por um corpo de válvula de segurança (32) car-regado por mola, disposto no lado do segundo anel de pistão (22) oposto à saída de válvula (16).
