Abstract
"VáLVULA DE RETENçãO BIDIRECIONAL PARA SISTEMAHIDRáULICO". Uma válvula de retenção bidirecional controla omovimento do fluido. Um corpo de válvula possui uma abertura,uma abertura adicional e uma passagem conectando a abertura ea abertura adicional. Um gatilho está disposto dentro da passagemdo corpo de válvula, e uma mola é acoplada no gatilho. Um gatilhoadicional está disposto dentro da passagem formada no primeirogatilho mencionado e uma mola adicional é acoplada no gatilho eno gatilho adicional. Quando o fluido que passa através daabertura no corpo de válvula exerce uma força no gatilho que émaior que a força de mola, a parte adicional da superfície externado gatilho é direcionado para longe da parte adicional da parededa passagem e permite que o fluxo flua da abertura no corpo deválvula através de um canal e na abertura adicional no corpo deválvula. quando o fluido que passa através da abertura adicionalno corpo de válvula exerce uma força no gatilho que é maior que aforça de mola adicional, a parte adicional da superfície externa dogatilho adicional é direcionado para longe da abertura adicional nocorpo de válvula para abrir o canal adicional e permitir que o fluidoflua da abertura adicional no corpo de válvula através do canaladicional, pelo menos uma abertura no gatilho adicional, apassagem adicional no gatilho adicional, a abertura adicional nogatilho adicional e a abertura no gatilho com a abertura do corpode válvula.
