のを防止すると同時に、これらの機器を冷却する
ために、冷却ブロアで吸引した外部空気の一部を
機械室内に導き加圧する方法がとられていた。
Generally, in locomotives, in order to prevent dust from entering the machine room and contaminating resistors, control devices, compressors, etc., and at the same time cooling these devices, a part of the outside air drawn in by a cooling blower is used. The conventional method was to introduce the part into the machine room and pressurize it.
この例を第１図、第２図を用いて説明する。冷

４に導かれ、この主電動機４内を冷却する。５は
主電動機４により駆動される車輪である。 This example will be explained using FIGS. 1 and 2. External air drawn in from outside the body by the cooling blower 1 is sucked in through the inertial filter 3 by the intake duct 2. A considerable amount of the external air that has been sucked in is guided through the air duct 6 to the main motor 4 supported by the truck, and cools the inside of the main motor 4. 5 is a wheel driven by the main electric motor 4.
一方、この冷却ブロア１からの冷却空気の一部

８、圧縮器９等を冷却すると同時に、機械室内を
車体外側より高く加圧して塵埃の侵入を防ぎ、機
械室のあちこちの隙間から外部に流出する。 On the other hand, a part of the cooling air from the cooling blower 1 is discharged into the machine room through the opening of the air duct 6a, and cools the heat source of the machine room, such as the resistor 7, control device 8, compressor 9, etc. The inside of the machine room is pressurized higher than the outside of the vehicle body to prevent dust from entering and flowing outside through gaps in the machine room.
この例では、塵埃が機械室に流入しないという
利点がある反面、冷却ブロア１が停止した場合、
機械室内の温度が急激に上昇するという問題があ
つた。即ち、省エネルギーのために機関車が停止

この場合に上記のような問題が発生する。
This example has the advantage that dust does not enter the machine room, but if the cooling blower 1 stops,
There was a problem that the temperature inside the machine room rose rapidly. That is, when a locomotive stops to save energy, the cooling blower 1 is often stopped even though the equipment in the machine room is in a heat dissipation state.
In this case, the above problem occurs.
また、この例では、機械室内に自然風が流れに
くいために炎天下にエンジンを停めた状態で機関
車が停止していた場合、機械室の温度が上昇し、
特に砂漠地帯では保守等のため機械室に入る時50
〜60度にもなり、苛酷な労働となつていた。 In addition, in this example, if the locomotive is stopped with the engine parked in the hot sun because it is difficult for natural wind to flow in the machine room, the temperature in the machine room will rise.
Especially in desert areas, when entering a machine room for maintenance etc.
Temperatures reached up to 60 degrees, making the labor grueling.
本考案の目的は、冷却ブロアが停止しても、機
