Abstract
In a load-responsive air braking system for a railway vehicle an electrical signal is transmitted from a brake controller actuated by an operator when he intends to apply a braking force. The signal is transmitted to a signal converter consisting of an electromagnet having a movable armature therein which contacts an end of a balance beam with a force corresponding to the electrical signal. The balance beam actuates a double valve which has a vent to the atmosphere and is connected between the braking cylinder and an air reservoir.
