Short travel detector for empty/load brake control |
摘要 |
An empty/load brake control system mountable on a sprung and an unsprung member of a railway car and disposed between the car brake control valve and brake cylinder for adjusting the brake cylinder pressure during a brake application according to the car load condition. Such system includes an empty/load sensor valve device and a sensor arm coupled to a sensor cable whose movement is controlled by a sprung member and a terminal member disposed on an end of sensor cable, in contact with sprung member so that any downward movement of sprung member forces such terminal member in a similar downward direction and similarly pulls on the sensor cable. A piston, under pressure, urges the sensor arm to rotate and retract sensor cable but must overcome resistance of a spring. The system includes a load proportional valve.
