Abstract

SISTEMA DE VÁLVULA EQUILIBRADA DE VAZAMENTO ZERO. Um conjunto de válvula para um dispositivo hidráulico. O conjunto de válvula tem uma sede de válvula dentro de uma passagem de válvula usada em combinação com um carretel. O carretel tem uma primeira seção em que um elemento flexivel está disposto dentro de uma cavidade da primeira seção tal que em uma primeira posição, o carretel e especificamente o elemento flexivel engata a sede de válvula para fornecer vazamento zero da passagem de válvula em uma passagem de tanque. Adicionalmente, o carretel é desenhado para ter uma seção adicional em uma segunda extremidade para fornecer áreas de vedação iguais em ambas as primeira e segunda extremidades do carretel para equilibrar as forças dentro da passagem de válvula.
