Definitions

  • the invention relates to ventilation openings on high-speed vehicles, in particular on high-speed rail vehicles.
  • the ventilation openings are used to supply and remove air for ventilation of the passenger compartments and are connected to the interior of the car via the air conditioning system.
  • the air vents for intake and exhaust air must be excluded from the airtight construction. Since the ventilation of the passenger compartments must take place in any case. However, it should be prevented that the pressure fluctuations in the passenger compartments which occur during train encounters are effective via the ventilation openings.
  • each ventilation opening which can be connected to a gas container (air container) via a solenoid valve and close the ventilation opening in the inflated state and Open the ventilation opening when not inflated:
  • An air container is advantageously arranged near the ventilation opening in order to achieve short lines. All devices for triggering the closing movement are expediently triggered by a pressure transmitter arranged at the head of the train.
  • the airbag can also be designed as a bellows or bellows. Air is advantageously used for the filling; nitrogen can alternatively be used as the gas at low temperatures. It is also possible to heat the contact surfaces at low temperatures in order to avoid freezing. To quickly open the Reaching ventilation openings can be accelerated by vacuuming.
  • the figures show exemplary embodiments of the invention.
  • FIGS 1 to 3 show a ventilation opening 1 in the vehicle wall 2.
  • This ventilation opening can be used for intake air or for outlet air.
  • This ventilation opening is provided with a grid 3.
  • the incoming air 4 is supplied via an air duct 5, to which circulating air 6 is also fed, in accordance with arrow 13 to an air conditioning system, not shown.
  • two perforated plates 7 and 8 are arranged, between which there is an inflatable air bag 9.
  • the perforated plate 7 and 8 and the airbag 9 are matched to one another so that the airbag tightly closes the air duct in the inflated state, as shown in FIG. 3.
  • the material of the airbag is so elastic that it also inflates seals in the corners and seals against possible dirt deposits. When depressurized, the airbag should collapse in such a way that there is a sufficiently large cross-section for the inlet air.
  • the airbag 9 is connected to a compressed air reservoir 10 via a pipeline with the interposition of a valve, e.g. a solenoid valve 12 connected. If necessary, the airbag can be opened by opening the solenoid valve from the storage container with e.g. 5 bar pressure can be inflated very quickly.
  • a valve e.g. a solenoid valve 12 connected.
  • the airbag is inflated in time in such a way that the pressure surge coming from outside the vehicle is sufficiently reduced and that no pressure surge is generated in the interior of the vehicle by the inflation of the airbag itself.
  • the airbag can be emptied more slowly after the external pressure surge has subsided; - it is caused by the overpressure in the airbag and by the elasticity of its material.
  • the evacuation can be accelerated by negative pressure using an injector nozzle.
  • Nitrogen can be used.
  • the transition from air to nitrogen can take place in the air tank via a rolling membrane.
  • pressure transducers for external pressure changes are provided.
  • An electronic circuit is used to evaluate the recorded pressure signal.
  • Pressure transducers are preferably installed at the top and at the end of the train (i.e. in the drive heads of multiple units). The pressure measured at the top or at the end of the train can act on pressure transducers, which I can be converted to the values to be expected on the wagons, in order to obtain criteria for actuating the locking devices. It is also possible to install the pressure transducer in any vehicle to be sealed, but with this type of installation the times for the timely closing of the locking device may not be sufficient.
  • the air tank is refilled each time the locking device is activated. Filling can be done from the main tank filling line of the train via a pressure switch or by means of a compressor installed on every vehicle.
  • the airbag can also be designed such that it lies against the sealing surface as a rolling bellows. In both cases, there is the advantage that the material of the airbag need not be as elastic as in the embodiment according to FIGS. 1 to 3.
  • FIGS. 4 and 5 show another embodiment of the invention, in which the airbag of FIGS. 1 to 3 is divided into several smaller air volumes.
  • FIG. 5 shows a section along the line V-V of FIG. 4, while FIG. 4 shows a section along the line IV-IV in FIG. 5 shows.
  • the airbag consists of several smaller air elements.
  • Each inflatable air element consists of a molded part 40 made of rubber-elastic material.
  • Each molded part is tubular at its two ends 41 and 42, while the central part 43 is flat in the non-inflated state and also tubular in the inflated state. 4 and 5, four elements are shown. Depending on the size of the ventilation opening, the number of elements can be adjusted accordingly.
  • the elements are located between perforated plates 45 and 46 and are also separated from one another by support plates 47.
  • the compressed air from the air tank, not shown here, is supplied to all elements on the right and / or left side (48).
