    摘要： The present invention relates to a brake assembly for a vehicle having an air spring wherein a brake signal operates a brake cylinder of the vehicle. A proportioning valve, having its load responsive element disabled and being responsive to the brake signal, provides a proportioned brake signal to the brake cylinder. A switch, responsive to an air spring pressure signal selectively connects the brake signal to the brake cylinder. The present invention further relates to a method for retrofitting a brake system by disabling the load sensing element of a proportioning valve and inserting a switch in parallel with the proportioning valve.

    摘要： A fluid pressure control portion for a fluid brake motor is inserted in a fluid pressure control passage between a triple valve and a brake motor for a particular car truck. This portion comprises a proportioning valve connected to an inshot valve through a pipe bracket to proportionally reduce brake pressure on a particular brake motor, after inshot at the same pressure as other brake motors of the same vehicle to adjust braking in accordance with lighter loading of end trucks for articulated freight cars.

    摘要： A test device and a method of testing leakage of a brake cylinder on a railroad car having a brake pipe and brake valve. The method includes charging the brake pipe, discharging the brake pipe at least at a service rate to actuate the brakes by charging the brake cylinder and simultaneously with charging the brake cylinder charging a reference volume to the brake cylinder pressure. Discharging of the brake pipe is terminated and the pressure in the reference volume is maintained. The difference of pressure between the brake cylinder and the reference volume, at a fixed period after the beginning of maintaining the pressure in the reference volume, is measured to determine the leakage.
