A two-pressure control valve that supplies air to the brake cylinder and keeps the auxiliary air reservoir in communication with the brake cylinder during emergency braking, and a two-pressure control valve that communicates the volumetric air reservoir with the brake cylinder when the vehicle is empty and also maintains this communication with the brake cylinder. Shut off when driving 2
In a cargo/pneumatic brake system equipped with a pneumatic/pneumatic switching valve having a position, a safety valve is provided in the volumetric air reservoir, and the set pressure of this safety valve is set to the normal full brake cylinder pressure when the vehicle is empty or slightly higher than that. A special feature of the loading and unloading brake system.
