Abstract

VEDAçãO Uma vedação isoladora compreende um elemento de estator (17) para localização dentro do estator do equipamento rotativo e um elemento de rotor (14) para localização sobre um eixo rotativo do equipamento rotativo. Esses dois elementos provêem superfícies adjacentes respectivas (82/83) e um dispositivo de desligamento estático (81) engata ambas as superfícies adjacentes quando o elemento do rotor está estático e desengata uma ou mais das ditas superfícies quando o elemento do rotor está dinâmico. Em um aspecto da presente invenção pelo menos uma das ditas superfícies é inclinada para o eixo geométrico longitudinal em um ângulo maior ou menor do que 90 . Em um aspecto adicional da presente invenção, o dispositivo de desligamento estático compreende um elemento de vedação anular resiliente (354) e um elemento auxiliar (357), móveis entre uma primeira posição, quando o elemento do rotor está estático, na qual o dito elemento auxiliar comprime o dito elemento anular resiliente para engate com ambas as ditas superfícies, e uma segunda posição na qual a compressão no dito elemento resiliente é reduzida, por meio disso o elemento anular resiliente desengata uma ou mais das ditas superfícies do rotor e estator quando o rotor está dinâmico.
