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 save labor by omitting an air volume controlling work according to the seasonal change of a ventilator. SOLUTION: An in-car pressure release valve 4 is normally in an open condition to mitigate any fluctuation of the in-car pressure caused by the differential temperature between inside and outside the car. The pressure outside the car is detected by a pressure sensor and the in-car pressure release valve 4 is closed only when the pressure outside the car is largely fluctuated. Labor can be saved thereby by re-controlling the air volume to be exhausted of the ventilator for the seasonal change, and omitting the controlling work for setting the in-car pressure within the reference.

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.

摘要翻译：要解决的问题：为了实现对气密车体的车辆中的外部空气温度的变化而引起的客舱压力的调整的自动化。解决方案：通过在膨胀系数不同的接合板31b，31c而获得的空气量调节板31布置在供气侧通道的中间，使空气量调节板31对应于外部空气温度的变化而变形。当外部空气温度升高时，板31向下游侧弯曲以扩大流路面积并扩大外部空气。结果，机舱压力增加。外部空气温度的降低对空气量调节板31产生不利影响，减小流路面积，减少外部空气量并降低客舱压力。由此，能够将车厢内的压力保持为基本恒定。版权所有（C）2004，JPO
