摘要： PROBLEM TO BE SOLVED: To automate a cleaning work by installing a windmill, a cleaning brush and a filter on a flow passage on an air supply side of a ventilation device, rotating the windmill and the cleaning brush by wind force when sucking the air supply, and automatically cleaning the filter, etc.
SOLUTION: The windmill 7 is provided on this side of the filter 6 installed in a fresh air suction port 5 on the air supply side of the ventilation device. The windmill 7 is rotated by wind force when sucking fresh air 1. The rotational force is transmitted to a shaft 11 with a brush via a rotary shaft 9 and a wheel 10. Trash and dust piled on the filter 6 are eliminated due to movement of the shaft 11 with the brush to automatically clean the filter 6.

摘要： PROBLEM TO BE SOLVED: To attain the automation of the adjustment of cabin pressure incident to a change in outside air temperature in a rolling stock of an airtight vehicle body.
SOLUTION: An air quantity adjustment plate 31 obtained by bonding plates 31b, 31c different in expansion coefficients is arranged in the middle of an air supply side channel, deforming the air quantity adjustment plate 31 corresponding to a change in outside air temperature. When the outside air temperature is increased, the plate 31 bends to the downstream side to enlarge a flow channel area and to expand outside air. Resultantly, the cabin pressure is increased. A decrease in outside air temperature adversely affects the air quantity adjustment plate 31, decreasing the flow channel area, reducing the outside air quantity and lowering the cabin pressure. Thereby, the cabin pressure can be maintained substantially constant.

摘要： PROBLEM TO BE SOLVED: To provide a ventilating device for a vehicle capable of securing the specified ventilating wind quantity even if the operating frequency of the device is altered and controlling the season control of the intra-vehicle pressure easily. SOLUTION: The ventilating device for the vehicle includes a supply/exhaust passage furnished with a rate-of-flow control device 40 capable of setting the resistance of the supply/exhaust passage to any value as desired so that the specified ventilating wind quantity can be maintained even if the operating frequency of the ventilating device is changed. The rate of opening of the rate-of-flow control device 40 is controlled interlocking with the operating frequency of the ventilating device so that the conventional problems are solved. The intra-vehicle temperature and the extra-vehicle temperature are sensed and their difference is computed, and on the basis of the result obtained, the rate-of-flow control device 40 is controlled, and it is possible to preclude any obstruction in opening and closing the door resulting from a rise of the intra-vehicle pressure.

摘要： PROBLEM TO BE SOLVED: To enable easy opening of a plug door for passengers to get on/off a high-speed railway vehicle.
SOLUTION: A first means is for heating air (60) on the entering side of an air feeding fan 33 for ventilation and for feeding air. This lowers the density of feeding air, and by feeding air, pressure inside the vehicle due to heating is prevented, and the problem of the plug door being difficult to open due to rising pressure is prevented. A second means is for reducing pressure inside the vehicle when the speed of the vehicle is a predetermined speed or less by stopping a fan device 20 of the ventilation device, so that the problem of the plug door being difficult to open is prevented. The operation of the fan device 20 of the ventilation device should be restarted right after stopping.
