<p>A hydraulic brake system for a trailer which is coupled to a mechanically braked towing vehicle has an electronic regulator circuit receiving signals from a first transducer which indicates the magnitude of the mechanical braking force and from a second transducer which indicates the fluid pressure in the cylinder or cylinders of the hydraulic brake system. The output of the regulator circuit is connected to one or more electromagnetic control valves which control a distributor valve serving to connect the pump with the brake cylinder or cylinders, with a return line and/or with one or more consumers. The regulator circuit insures that the fluid pressure in the brake cylinder or cylinders is always proportional to the mechanical braking force.</p> |
