Abstract

circuito de comando para operar um torquímetro ou uma unidade semelhante. a presente invenção rere-se a um conjunto de circuito para operar um torquímetro hidráulico, ou uma unidade semelhante, com uma unidade de pistão-cilindro (18), que pode ser ativada por uma bomba (11) com uma pressão predeterminável, que é caracterizado pelo fato de que a unidade de pistão-cilindro (18) pode ser ativada pela bomba (11) através de uma válvula proporcional (12), a qual age tanto como unidade de reversão entre a marcha à frente e marcha à ré, como também como válvula limitadora de pressão.
