The air supply ventilation device of the device draws in air on the one hand through the draft shield 14, the open pressure protection valve 12 and the fresh air duct 3 and on the other hand takes in the ventilation via the ventilation duct 4. Then, the supply air is supplied to the passenger compartment of the vehicle through the supply air duct 5. The appropriate ratio of ventilation to fresh air is provided by the ventilation drafts 7 or by the ventilation valve position,

ッチが入れられる。The exhaust air reaches the environment via the exhaust air duct 6, the exhaust ventilation device 9, the open pressure protection valve 13 and the wind shield 14. The bypass ventilation device 10 is provided in parallel with the fresh air pressure protection valve 12 and the exhaust air pressure protection valve 13.
And 11 are arranged. The bypass ventilators 10 and 11 are switched on by the pressure evaluation and control unit 15 as soon as an acceptable pressure fluctuation condition in the vehicle is exceeded, which may cause the pressure protection valves 12 and 13 to be closed.

The amount of air replenished from the outside as fresh air is returned to the environment by the exhaust ventilation device 9 via the exhaust air pressure protection valve 13 and the wind shield 14.

い。In the case of protecting the pressure with respect to an overpressure wave generated when passing through a tunnel or when a train passes each other, the pressure protection valve 12 for outside air is started at the same time when the amount of air flowing in due to the pressure difference before and after the valve is the same. It is closed almost corresponding to the carrying capacity of the bypass air ventilation device 11 for the exhaust air. As a result, the pressure does not increase inside the vehicle 1.

下が生じない。To protect the pressure with respect to the negative pressure wave,
The exhaust air pressure protection valve 13 is closed such that the amount of air flowing out due to the pressure difference across the valve corresponds approximately to the carrying amount of the bypass draft device 10 for fresh air started at the same time. As a result, no pressure drop occurs inside the vehicle 1.

らず、車両内圧がほとんど一定のままである。When the pressure amplitude of the pressure wave and the rate of pressure fluctuation are very large, the solution with the reduction of the cross section of the pressure protection valve and the operation of the respective bypass ventilator can no longer be achieved, or the control is simpler. As soon as the situation is recognized by the pressure evaluation and control unit 15, both pressure protection valves 12, 13 are closed and both bypass ventilators 10, 11 are started with maximum performance. . Thereby, the fresh air delivery and the exhaust air delivery match, so that the vehicle internal pressure remains almost constant despite the external pressure wave.
