る鉄道車両用空気ブレーキ装置。An emergency pressure limiting valve that limits the maximum brake pressure in the brake cylinder is connected to a three-pressure control valve that controls the air pressure supplied from the supply air reservoir to the brake cylinder according to the pressure difference between the constant pressure air reservoir and the brake pipe. In the air brake device for a railway vehicle, the supply air reservoir is composed of a first supply air reservoir and a second supply air reservoir, the first supply air reservoir is directly connected to the three-pressure type control valve, and the second supply air reservoir is directly connected to the three-pressure type control valve. The air reservoir is connected to the three-pressure type control valve via a switching valve, and the switching valve switches when the brake pipe pressure is reduced to a predetermined pressure close to atmospheric pressure to connect the second supply air reservoir to the three-pressure type control valve. and a first supply air reservoir, the capacity of the first supply air reservoir is set to a capacity at which the brake cylinder outputs the normal full brake pressure, and the capacity of the second supply air reservoir is set to the capacity at which the brake cylinder outputs the normal full brake pressure. An air brake device for a railway vehicle, characterized in that the brake cylinder is set to a capacity that outputs maximum brake pressure when the switching valve is switched.
