Abstract

Patente de Invenção:<B>"SISTEMA HIDRáULICO DE FREIO DE DOIS CIRCUITOS PARA UM AUTOMóVEL"<D>. Um sistema hidráulcio de freio de dois circuitos, com pelo menos um amplificador de potência de freio de subpressão em cada um dos dois circuitos de freio, particularmente para veículos de carga, com, respectivamente, uma ligação dos amplificadores de potência de freio a uma fonte de subpressão, sendo que os dois amplificadores de potência de freio, pelo menos quando de um aumento de pressão involuntário no lado da subpressão, acima de uma medida predeterminável, em uma das duas ligações que levam à fonte de subpressão, não possuem uma ligação compensadora de pressão entre si, está caracterizado pelo fato de que está previsto pelo menos um dispositivo produtor de subpressão (fonte de subpressão), manobrável independentemente do motor de combustão interna do veículo, pelo qual em cada um dos amplificadores de potência de freio de subpressão pode ser produzida uma subpressão, independentemente do respectivamente outro.
