制的に循環され、回転電機内で発生した熱は冷却器９に
よって冷却される。Next, the operation will be explained.The cooling medium, that is, air, inside the rotating electric machine is forcibly circulated by the cooling fan 2 as shown by the arrow in FIG. 2, and the heat generated inside the rotating electric machine is cooled by the cooler 9. Ru.
機内の圧力は、吸気ゾーン人と排気ゾーンＢにより大き
く分けられ、冷ＭＪ７アン２によって吸気ゾーン人が排
気ゾーンＢより低く、一般に機外の外気圧に比較して吸
気ゾーン人が負圧、排気ゾーンＢが正圧となる。The pressure inside the aircraft is broadly divided into intake zone people and exhaust zone B. Due to the cold MJ7 AN2, the intake zone people have lower pressure than the exhaust zone B, and generally the intake zone people have negative pressure and exhaust air pressure compared to the outside pressure outside the aircraft. Zone B has positive pressure.
従って、万一の冷却器９からの漏水や軸受箱８からの漏
油は、吸気ゾーン人に集まるため、漏水。Therefore, in the unlikely event that water leaks from the cooler 9 or oil leaks from the bearing box 8, the water will leak because it will collect on people in the intake zone.

ち、吸気ゾーン人に相当する個所に設けられている０な
３．この排水孔ｌＯハブラグＵによって塞がれ、回転電
機の密閉度を保っている。A drainage hole 10 for draining oil leakage, etc. is generally provided in a part of the stator frame 6 corresponding to the intake zone. This drainage hole 10 is closed by the hub plug U to maintain the airtightness of the rotating electric machine.
従来のドレン排水孔は１以上のようにプラグで栓をして
いたので１機内に漏水や漏油が起きても排出されず、加
えてこれらの異常に気付かないという重大な欠点があっ
た。Conventional drain holes were closed with plugs, so even if water or oil leaked inside an aircraft, it would not be drained, and there was a serious drawback in that these abnormalities could not be noticed.
この発明は上記のような問題点を解消するためになされ
たもので１機内に溜った漏水や漏油を自動的に排出し、
その異常も監視することが出来るドレン排出装置を得る
ことを目的とＴる。This invention was made to solve the above-mentioned problems, and automatically drains water and oil that accumulates inside the aircraft.
The purpose is to obtain a drain discharge device that can also monitor abnormalities.
この発明に係るドレン排出装置は、機内外の圧力差に応
じた水頭を待つ液溜り骨分設け、かつその出口に機外に
向ってのみ開通できる逆止弁機構を備えたものである。The drain discharge device according to the present invention is provided with a liquid reservoir that waits for a water head corresponding to the pressure difference between the inside and outside of the machine, and is equipped with a check valve mechanism at its outlet that can only be opened to the outside of the machine.
この発明に？けるドレン排水孔は、運転中において漏水
や漏油によって機内に液体が溜っても自動的に排出でき
る。For this invention? The drain hole can automatically drain any liquid that accumulates inside the machine due to water or oil leaks during operation.
以下この発明の一実施例を図について説明する。 An embodiment of the present invention will be described below with reference to the drawings.
第１図は要部の拡大ｌ！ｒ面図を示すもので、第１図に
８いて、丘は固定子枠６の底部に設けたドレン穴ｌＯに

同様であるので説明ご省略する。Figure 1 is an enlargement of the main part! 8 in Fig. 1, the hill is a liquid reservoir pipe provided in communication with the drain hole lO provided at the bottom of the stator frame 6, and 13 is a non-return check provided at the tip of the liquid reservoir pipe. It is a valve. The structure and other structures are the same as those of the conventional example described above, so a description thereof will be omitted.

なされている。Next, the effect will be explained. As mentioned above, if liquid accumulates inside the aircraft due to water or oil leakage, the height of water (P
, ) is collected in the drain pipe. If any more liquid accumulates, the check valve 13 opens outward to drain the liquid.
