Abstract

trata-se de um aparelho hidráulico que inclui uma primeira tubulação de válvula que fornece uma capacidade de desligamento e uma segunda tubulação de válvula que fornece uma capacidade de controle de excesso de velocidade. o aparelho hidráulico vantajosamente emprega de modo adicional um instrumento hidráulico que inclui uma válvula de verificação e um aparelho de desvio. o instrumento hidráulico possibilita que a segunda tubulação de válvula forneça adicionalmente, como uma função alternativa, uma capacidade de desligamento redundante, eliminando, dessa forma, a necessidade de ter três tubulações de válvula separadas.
