Abstract

"AMORTECEDOR". Uma válvula para o líquido controlando corre através de uma passagem definida por um corpo de válvula ou um pistão inclui um disco da válvula que abuts o corpo de válvula ou o pistão. O corpo de válvula ou o pistão definem um primeiro membro suportando para o disco da válvula, um segundo membro suportando para o disco da válvula situado radial para dentro do primeiro membro suportando e de um terceiro membro suportando para o disco da válvula situado entre os primeiros e segundos membros suportando. Este disco da válvula abuts o primeiro e os segundos membros suportando e um afastamento são definidos entre o disco da válvula e o terceiro membro suportando.
