This air flowpassage adjustable means will be described in detail later.
  • Reference numerals 20a and 20b designate flexible plates each having one end secured to the wall surface of an air flowpassage and the other being a free end which can freely swing.
  • the flexible plates 20a and 20b are arranged at the right angle with respect to the air flowing direction.
  • the shape of the flexible plates 20a and 20b coincides with the sectional shape of the air flowpassage and a swingable clearance is provided in the outer periphery to form a shape which blocks the air flowpassage.
  • the flexible plates 20a and 20b are arranged alternately so that respective fixed ends are positioned on the opposite ends.
  • a stopper 21a is provided upstream of the air flowpassage of the flexible plate 20a, and a stopper 21b is provided downstream of the air flowpassage of the flexible plate 20b.
  • the stopper 21a supports the flexible plate 20a so that the flexible plate 20a will not deflect toward the upstream of the air flowpassage from the position at the right angle to the air flowing direction.
  • the stopper 21b supports the flexible plate 20b so that the flexible plate 20b will not deflect toward the down­stream of the air flowing passage from the position at the right angle to the air flowing direction.
  • the flexible plate 20a has a rigidity by which the plate is not deflected when the normal air flow, as indicated by the dotted lines arrow in Figs. 2, 3 and 4, and has a rigidity by which when the air flow increases more than that of the normal state and the air flow indicated by the solid line arrow in Fig. 3 impinges upon the plate, the plate is deflected.
  • the flexible plate 20b is lower in the rigidity than the flexible plate 20a, and has the rigidity to the extend that the flexible plate 20b is deflected a reverse flow of air as indicated by the solid line arrow in Fig. 4 occurs.
  • Reference numeral 22a designates a guide plate provided upstream of the air flowpassage of the flexible plate 20a.
  • the guide plate 22a has the size corresponding to the whole surface of the flexible plate 20a to prevent the air flow from directly applying the flexible plate 20a.
  • the guide plate 22a has a curved shape for smoothly guiding the air flow.
  • Reference numeral 22b designates a guide plate provided downstream of the air flowpassage of the flexible plate 20b.
  • the guide plate 22b has the size corresponding to the whole surface of the flexible plate 20b to prevent the air flow from directly applying the flexible plate 20b in case of reverse air flow.
  • Fig. 2 shows the normal ventilating state of the air flowpassage adjustable means. Both the flexible plates 20a and 20b stay still at the right angle to the air flow direction under the normal ventilating state.
  • C and D When two vehicles pass each other during the running of the vehicles in the tunnel, pressure outside the vehicles suddenly changes as indicated by C and D in Fig. 10.
  • the state shown at C in Fig. 10 shows the state that the pressure outside the vehicles suddenly increases.
  • the function of the air flowpassage adjustable means 4 under this state will be described with reference to Fig. 3.
  • the air flowpassage is shut off by the flexible plate 20a, thus the ventilation of the vehicle is not dore.
  • the time when the vehicles pass each other within the tunnel and the duration of the change of pressure outside vehicles is only a few seconds. Accordingly, even if the air outside vehicles is not supplied into the vehicle, there occurs no problem.
  • the function of the air flowpassage adjustable 4 when the pressure outside vehicles suddenly drops as indicated as D in Fig. 10 will be described with reference to Fig. 4.
  • the air in the air flowpassage is reversed by the large change in pressure.
  • the flexible plate 20b is deflected toward the flexible plate 20a as the result that the pressure on the side of the flexible plate 20a is lower.
  • the area of the air flowpassage can be narrowed as the result that the flexible plate 20b deflects. Accordingly, the transmission of the pressure outside vehicle into the vehicle can be regulated. If the change in pressure outside vehicle is large, the flexible plate 20b shuts off the air flowpassage. At this time, a supply of air outside vehicle stops, which brings no problem because such duration of such a phenomenon is in a short period of time.
  • the operating condition when the pressure outside vehicle of the air flowpassage adjustable means increases corresponds to that shown in Fig. 4.
  • the operating condition, when the pressure outside vehicle of the air flowpassage adjustable means 12 decreases, corresponds to that shown in Fig. 3.
  • the flexible plates 20a and 20b of the air flowpassage adjustable means 4 or 12 are deflected to narrow the area of the air flowpassage. If the pressure change is large, the air flowpassage is shut off. The air flowpassage is narrowed or shut off in this manner whereby the transmis­sion of the change in pressure outside vehicle into the vehicle or the passanger compartment 7 can be prevented. Thus, the uncomfortableness to the passengers resulting from the change in pressure outside vehicle can be prevented.
  • the flexible plate 20b has lower rigidity than the flexible plate 20a. That is, the flexible plate 20b is not deflected in the normal operating state since it is supported by the stopper 21b.
  • the flexible plate 20b is formed to have a low rigidity so that incase a reverse flow occurs in the air flowpassage, the area of the air flowpassage can be rapidly narrowed.
  • the reverse flow of air in the air flowpassage of the air supply equipment 3 and exhaust air equipment 10 causes the pressure in the vehicle to change rapidly. It is therefore particularly effective that when the reverse flow occurs, the area of the air flowpassage is rapidly narrowed.
  • the guide plates 22a and 22b can prevent a deflection in excess of a specified value of the flexible plates 20a and 20b. Accordingly, by installation of the guide plates 22a and 22b corresponding to the flexible plates 20a and 20b as previously mentioned, the self-­excitation oscillations of the flexible plates 20a and 20b can be prevented.
  • Reference numeral 20c designates a flexible plate in which flaps 23 are mounted on both ends.
  • the flaps 23 are mounted on the flexible plate 20c by supports 24 such as rivets, screws or the like.
  • the flaps are in contact with the inner wall of the air flowpassage. Accordingly, by the deflection of the flexible plate 20c, the resistance due to the friction occurs between the flap 23 and the inner wall of the air flowpassage. The self-excitation oscillations of the flexible plate 20c can be prevented by the resistance. If the flaps 23 are provided on the flexible plate, said guide plates 22a and 22b need not be provided.
  • the contact force of the flaps 23 on the inner wall of the air flowpassage or the rigidity and width of the flaps themselves can be freely adjusted by the rigidity of the flexible plate 20c or the maximum value of the change in pressure outside vehicle.
  • reference numeral 31 designates an air supply equipment for taking air outside vehicles into the vehicle.
  • Reference numeral 32 designates an outside-air intake grille mounted on the opening of the roof.
  • Reference numeral 33 designates a blower consti­tuting said air supply equipment 31.
  • the blower 33 has the performance in which the flow quantity is less changed with respect to the variation in pressure outside vehicles.
  • the performance of the blower 33 can be controlled stepwise. The lowest performance among the performance of the blower 33 is the performance which can supply the flow quantity as required into the vehicle under the normal operating condition.
  • Reference numeral 34 designates a damper provided upstream from the blower 33 of the air flowpassage taking air outside vehicles into the vehicle. This damper can change an area of the air flowpassage installed. In other words, the damper 34 can change the resistance R of the air flowpassage.
  • Reference numeral 35 designates a duct, which has the function similar to that of the duct 5 in the previous embodiment.
  • Reference numeral 36 designates a diffusers provided in the duct 35.
  • Reference numeral 37 designates a passenger compartment.
  • Reference numeral 40 designates an exhaust air equipment for exhausting contaminated air within the vehicle outside the vehicle.

  • Reference numeral 41 designates a blower constituting an exhaust device 40.
  • the blower 41 has the function similar to that of the previous blower 33.
  • Reference numeral 42 designates a damper installed upstream of the blower 41 of the air flowpassage for exhausting contaminated air within the vehicle outside the vehicle. This damper 42 can change an area of the air flowpassage. In other words, the damper 42 can change the resistance R of the air flowpassage.
  • the blowers 33 and 41 have the performance the solid lines P1-Q1, P2-Q2 and P3-Q3. The performance of the blowers 33 and 41 may be adjusted by varying the number of revolutions thereof.
  • the dampers 34 and 42 have the resistance characteristics of the dotted lines R1, R2 and R3 in Fig. 8. The dampers 34 and 42 are controlled to provide different of resistance characteristic.
  • Reference numeral 43 designates a pressure detector for detecting pressure outside vehicles.
  • Refer­ence numeral 44 designates a controller for controlling the blowers 33 and 41, the dampers 34 and 42 using, as the control inputs, the detected results which are sent from the pressure detector 43.
  • the controller 44 calculates and judges the results of pressure detection obtained from the pressure detector 43, switches the performance of the blowers 33 and 41 and switches the resistance character­istics of the dampers 34 and 42.
  • axis of abscissa represents time passage t (min), and the axis of ordinate represents pressure P (mm Aq).
  • Fig. 9 shows the uncomfortableness region A in which passengers within the vehicle feed the uncomfort­ableness with respect to the absolute value Px of the change in pressure outside the vehicles and the variation gradient dP/dt in change of the pressure outside the vehicles.
  • the axis of abscissa represents the absolute value Px of the change in pressure outside the vehicles
  • the axis of ordinate represents the gradient dP/dt in change of the pressure outside the vehicles.
  • the hatched portion in Fig. 4 is the uncomfortable region A.
  • This uncomfortable region A is experimentally known.
  • the cause wherein passengers in the vehicle running at high speeds feel uncomfortable is the absolute value Px of the change in pressure outside the vehicles and the gradient dP/dt in change of the pressure outside the vehicles.
  • the pressure outside the vehicles change as shown by P out in Fig. 10.
  • the pressure outside the vehicles at that time are continuously detected by the pressure detector 43 to output the detection results to the controller 44.
  • the controller 44 calculates and obtains the gradient dP/dt in change of the pressure outside the vehicles and the absolute value Px of the change in pressure outside the vehicles on the basis of the detected results which are sent from the pressure detector 43.
  • the performance of the blowers 33 and 41 and the resistance characteristics of the dampers 34 and 42 given in Table 1 below are selected from values of dP/dt and Px obtained by the controller 8.
  • the controller 44 outputs, as the control outputs, the results calculated and judged as mentioned above to the blowers 33, 41 and dampers 34, 42.
  • the blowers 33, 41 and dampers 34, 42 are operated by the control output from the controller 44.
  • a change in the maximum pressure P max occurs in a short period of time.
  • the absolute value Px of the change in pressure and the gradient dP/dt in change of the pressure increase in value. If the absolute value Px of the change in pressure is less than the maximum pressure, for example, 400 mm Aq, of the blowers 33 and 41, the operation is made with the performance of blowers 33 and 41 in the range of minimum P3-Q3 to maximum P1-Q1.
  • the dampers 34 and 42 are controlled in the range from R1 at which the resistance is minimum to R3 at which the resistance is maximum.
  • the blowers 33 and 41 are controlled by the controller 44 to enhance the pressure characteristic of the blowers 33 and 41 as the absolute value Px of the change in pressure outside the vehicles increases, whereby the change in flow quantity resulting from the change in pressure outside the vehicles can be reduced.
  • the operation is made so that the resistance of the dampers 34 and 42 increases as the dampers 34 and 42 of the controller 44 are controlled and the gradient dP/dt in change of the pressure outside the vehicles increases.
  • the dampers 34 and 42 are closed as the gradient dP/dt in change of pressure outside the vehicles increases, the propagation of the pressure outside the vehicles into the vehicle can be regulated. In this manner, the change in flow quantity of the blowers 33 and resulting from the change in pressure outside the vehicles can be regulated and the transmission of the pressure outside the vehicles into the vehicle can be regulated, and therefore, the variation is pressure within the vehicle can be regulated at minimum.
  • the dampers 34 and 42 are completely closed. Also, if the absolute value Px of the change in pressure outside the vehicles exceeds the maximum pressure of the blowers 33 and 41, for example, 400 mm Aq, the dampers 34 and 42 are completely closed. Where the change in pressure outside the vehicles is extremely large, the vehicle is completely closed. The state wherein the pressure outside the vehicles is changed largely as described above is for a short period of time, causing no problem in securing the exhaust an quantity.
  • the vehicle is closed, and therefore, it is possible to minimize the influence of the change in pressure outside the vehicles to the passengers can be eliminated.
