FIELD: transportation.
SUBSTANCE: valve operator for the high availability air brake system contains an inlet for compressed air, an outlet for compressed air and a safety inlet. The compressed air inlet is connected to the outlet of the trigger valve device to supply a specific inlet pressure to the valve operator. The outlet for compressed air is connected to the accelerator valve device to supply the outlet pressure device to the accelerator valve. The safety inlet is connected to a source of compressed air. The valve operator in the first switch position hydraulically connects the safety input to the compressed air outlet, and in the second switching position, hydraulically connects the compressed air inlet to the compressed air outlet and, in accordance with the operator data, converts the inlet pressure to prepare the outlet pressure.
EFFECT: possibility of providing a certain predetermined deceleration in the braked properties deviation operating modes.
