Fluidic control system for vehicle brakes
Abstract
Abstract AN ELECTRO-PNEUMATIC BRAKE CONTROL APPARATUS FOR A TRAIN OF SELF-PROPELLED COUPLED CARS, IN WHICH THE PRESSURE IN A TRAIN LINE PIPE IS CONTROLLED BY APPROPRIATE ENERGIZATION AND DEENERGIZATION OF RELEASE AND APPLICATION MAGNET VALVE DEVICES PROVIDED ON EACH CAR IN THE TRAIN FOR SUPPLYING FLUID UNDER PRESSURE THEREFROM. THE ENERGIZAOR RELEASING FLUID UNDER PRESSURE THEREFROM. THE ENERGIZATION AND DEENERGIZATION OF THE MAGNET VALVE DEVICES IS CONTROLLED VIA TRAIN LINE WIRES BY PNEUMATICALLY OPERATED SWITCH DEVICES ON THE LEAD CAR IN THE TRAIN. THESE SWITCH DEVICES ARE SELECTIVELY OPERATED BY A PLURALITY OF PURE FLUID DEVICES IN CORRESPONDENCE TO THE OPERATION OF A BRAKE VALVE ALSO ON THE LEAD CAR TO ESTABLISH SUITABLE CONTROL CIRCUITRY VIA THE TRAIN LINE WIRES TO THE RELEASE AND APPLICATION MAGNET VALVE DEVICES SO AS TO CAUSE EITHER THE CHARGING OF OR A REDUCTION OF PRESSURE IN THE TRAIN LINE PIPE, IT BEING UNDERSTOOD THAT VARIATIONS OF THE FLUID PRESSURE IN THE TRAIN LINE PIPE ARE EFFECTIVE TO CONTROL BRAKE APPLICATIONS AND BRAKE RELEASES ON THE CARS IN THE TRAIN.
