Abstract

"VáLVULA DE FREIO HIDRáULICO". Uma válvula de freio hidráulico, que compreende um corpo, uma passagem definida no corpo, uma entrada para a passagem, uma saída a partir da passagem e um elemento de válvula móvel na passagem, o referido elemento de válvula tendo uma primeira condição que bloqueia a passagem, para impedir uma comunicação entre a entrada e a saída, e uma segunda condição, onde o elemento de válvula é adaptado para manter a passagem aberta para permitir uma comunicação entre a entrada e a saída, em resposta a um diferencial de pressão que exceda a um valor predeterminado, o elemento de válvula permanecendo em sua segunda condição, uma vez que tenha se movido para sua segunda condição.
