Additional cylinder is hinge-mounted on vehicle bogie in parallel with main cylinder. Rod of additional cylinder is fitted in slot of shackle for translation, shackle being hinge-secured on bell crank of main brake cylinder. Piston of additional cylinder is spring-loaded from side of rod by compression spring, its underpiston space communicates with atmosphere and its overpiston space communicates with standby reservoir through pipeline. ^ EFFECT: prevention of self-movement of rail vehicles cut off from locomotive. ^ 1 dwg |
