この圧力変動がキヤビン内に伝わって、乗客に不快感を
与える。The conventional railway vehicle ventilation device has the following problems. That is, when a railway vehicle moves at high speed in the atmosphere, the air pressure on the surface of the vehicle body fluctuates from moment to moment. Especially when a train running at a high speed enters a tunnel, the air pressure on the surface of the vehicle body fluctuates rapidly.
This pressure fluctuation is transmitted to the cabin and makes passengers uncomfortable.

ビン内を換気することができない。The degree increases as the speed of the railway vehicle increases. As a countermeasure against this, it is conceivable to close the air intake and exhaust ports during the operation period, but it is not possible to ensure the airtightness of the railway vehicle, and 100% transmission of pressure fluctuations into the cabin is possible. I can't shut it down. Also, the inside of the cabin cannot be ventilated while the air intake and the exhaust are closed.

しようとする点にある。It is also possible to install a ventilation fan capable of maintaining a constant air flow rate regardless of pressure fluctuations. In this case, however, the higher the traveling speed of the railway vehicle,
Since it is necessary to install a large ventilation fan, there is a problem that power consumption and vehicle weight increase. The present invention is proposed in view of the above problems, and an object thereof is to open a vehicle body surface without opening or closing an air inlet and an exhaust port or installing a large ventilation fan. It is possible to prevent air pressure fluctuations from being transmitted to the cabin. Another object of the present invention is to provide a railcar ventilation device that can reduce the resistance of the air intake and exhaust systems.

内に圧力を大きく変動しないように保持する。Next, the operation of the railcar ventilation device shown in FIG. 1 will be specifically described. When the railway vehicle is traveling, the outside air B is sent into the cabin A through the air intake on the movable member 1a side → the residual heat exchanger 6 → the flow path switching valve 7 → the air conditioning air outlet 10. In addition, the air in the cabin A is sucked into the cabin air inlet 9 →
The total heat exchanger 6 is exhausted to the outside of the vehicle through the exhaust port on the movable member 1b side to ventilate the inside of the cabin A, while the detection signal detected by the intake air flow rate sensor 4 and the cabin pressure sensor 5 is sent to the controller 3. The deviation of detection signals from the respective sensors 4 and 5 is calculated, and each actuator 2 is operated based on the result to swing the movable member 1a of the air intake port and the movable member 1b of the exhaust port. By swinging around 1a 1 and 1b 1 in the direction of the arrow, while maintaining the required ventilation, the Cabin A
Keep the pressure inside so that it does not fluctuate significantly.

従って可動部材1a,1bの突出量を増減することによ
り、ラム圧と排圧との差分が調整可能になる。At this time, the air intake port becomes larger as the amount of protrusion of the movable member (vane) 1a from the vehicle body increases.
The intake amount of outside air increases, and the ram pressure corresponding to the traveling speed is obtained. The exhaust pressure of the exhaust port decreases as the amount of protrusion of the movable member (vane) 1b from the vehicle body increases.
Therefore, the difference between the ram pressure and the exhaust pressure can be adjusted by increasing or decreasing the protruding amount of the movable members 1a and 1b.

口になり、可動部材1b側が空気取入口になる。The ventilation amount is determined by a balance between the intake area, the difference between the ram pressure and the exhaust pressure, and the total pressure loss of the in-vehicle ventilation system. Further, by adjusting the protrusion amount of the movable members 1a and 1b with respect to the fluctuation of the external atmospheric pressure, the total exhaust amount is kept in balance, and the pressure in the cabin A is held so as not to largely change. FIG. 2 shows the flow of air when the flow direction switching valve 7 is switched because the traveling direction of the railway vehicle is reversed, and in this case, the movable member 1a side serves as an exhaust port and is movable. The member 1b side serves as an air intake.
