ABSTRACT:
In a power braking system for a vehicle a supply of fluid from a power source is utilized to augment the output pressure to be supplied to a brake from a pedal-operated brake control valve assembly. The power source comprises a source of hydraulic fluid of a type different from that which is supplied to the brake from the control valve assembly, and the fluid under pressure from the pressure source is supplied to at least one pressure converter which is adapted to pressurize hydraulic fluid in a sub-system to augment the output pressure from the control valve assembly. The sub-system is provided with hydraulic fluid of a type different from that of the power source, and an hydraulic accumulator is incorporated in a line between the pressure converter and the control valve assembly.
