Abstract: Systems and methods of overriding a conventional trailer emergency brake system to preclude and alert others as to inadvertent or premature movement of the trailer are described herein. One implementation includes a safety valve operatively positioned in the emergency braking system of a trailer that may be engaged to override the brake valve located in a tractor to prevent a truck driver from prematurely or inadvertently moving the trailer. In addition, the system may include a one way check valve to allow hydraulic fluid upstream of the safety valve to bleed out of the brake system when the safety valve is closed (to prevent movement of the trailer) before the emergency brakes for the trailer are set by the driver. A communication system may also be provided to alert the driver via a remotely located computing device that the emergency brakes for the trailer need to be set.

Abstract: The invention relates to a brake system for a railway vehicle. Said brake system comprises a main air reservoir line which is fed by an air compressor unit. Every bogie truck is provided with at least one compressed-air line which is connected to the main air reservoir line either directly or via a stop valve, a non-return valve and a compressed-air reservoir. The compressed-air line feeds, for example, the service brake valves for impinging the brakes of the bogie truck or a control unit for the spring-loaded brake and/or other control units for other auxiliary components. The service brake valves and/or the spring-loaded brake and/or other auxiliary components are controlled via at least one local, electronic brake control unit.

Abstract: The calibration process according to the invention, intended for a pneumatic-assistance servomotor for a braking circuit of a motor vehicle, consists in measuring and recording, on the basis of a given negative-pressure value (Pfc) inside the negative-pressure chamber of a servomotor, the values of the output pressure (Pmc) of the hydraulic master cylinder associated with said servomotor, and of the negative pressure inside the working chamber of the servomotor, for several operating points P1, P2, P3, P4 of the servomotor, located on either side of the saturation point so as to determine the coordinates of the saturation point precisely, for an accurate control of the advanced functions, as concerns the braking operation, the braking assistance and/or the monitoring of the performance or of the ageing of the servomotor.

Abstract: A combined hydropneumatic brake cylinder/air reservoir device having a hydraulic piston formed on the end of a push rod through which interconnected, different sized, pneumatic pistons operate to transmit the desired brake force. The hydraulic piston operates in a hydraulic cylinder having a slack adjuster piston arranged to supply or reduce the hydraulic fluid in the braking circuit in order to compensate for overtravel and undertravel of the pneumatic piston assembly due to brake shoe wear and brake shoe replacement respectively. The double-acting slack adjuster action results in the stroke of the pneumatic piston assembly being maintained constant to assure continued optimum operating efficiency.

Abstract: A fusible plug closed vent line for the ''''Westinghouse Brake System'''' of a railway car and having a pressure differential actuated control valve operatively associated therewith and responsive to a reduction in air pressure downstream from the control valve to shift the latter from a closed position to an open position for free venting of the associated ''''Westinghouse Brake System'''' upon a reduction of air pressure in the vent line downstream from the control valve as would occur when one or more of the fusible plugs closing the vent line downstream from the control valve are melted. The control valve includes an exteriorly disposed actuator that may not only be operated to close the control valve, but also indicates, in a visual manner, when the control valve has been shifted to the open position.
