のである。
従来の技術 従来、この種の圧縮機は、実開昭５８−１８１９９２号
公報に記載され第１図に示すように構成されている。
以下、図面を参照しながら説明する。
今 第亀図において、１は密閉容器であり、密閉容器１の上
部に電動機部２、下部に圧縮機部３が収納されている。
電動機部２はステータ４とロータ５より構成されている
。６は軸であり、電動機部２のロータ５と圧縮機部３を
連結している。７は分離板であり、ロータ５の上部に挿
入された支持棒８に固定されている。９は吐出管であり
、分離板７の中心位置にある。１０は潤滑油であり、圧
縮機部３の周囲に貯留されている。
以上のように構成された圧縮機について、以下その動作
について説明する。
電動機部２により駆動された圧縮機部３において、ガス
冷媒は吸入、圧縮され、圧縮機部３の上部空間に吐出さ
れる。一方、圧縮機部３に内蔵されている油ポンプによ
り圧縮機部３の摺動部へ供給された潤滑油１０は、圧縮
機部３の上部にある軸受から流出するとともに、１ｌｉ
ＩＩ＋６及びロータ５の回転により霧化される。そして
、圧縮機部３から吐出さねたガス冷媒に潤滑油１０はま
き込まわ、電動機部２の上部空間に至る。ここで、吐出
管９に至る流れの経路において、霧化された潤滑油１０
は分離板７の遠心分離作用を受けてガス冷媒から分離さ
れ、吐出管９からはガス冷媒のみが吐出されるようにし
ている。
発明が解決しようとする間ぷ点 しかしながら上記のような構成では、圧縮機の回転速度
が速くなると、油ポンプの揚油量が増え、それに伴ない
霧化される潤滑油量も増加し、分離板の潤滑油分の分離
能力以上になり、圧縮機外へ吐出される潤滑油量は多く
なる。その結果、圧縮機内部の潤滑油が不足し、圧縮機
部の摺動部への潤滑油供給が不十分となり、金属接触等
により摺動部の摩耗が増大するという問題点を有してい
た。
本発明は上記問題点に鑑み、高速運転における潤滑油の
膠化を抑制し、圧縮機内部の潤滑油不足を防止できる圧
縮機を提供するものである。
問題点を解決するための手段 上記問題点を解決するために本発明の圧縮機は、電動機
と、電動機に駆動される圧縮機構と、電動機と圧縮機構
を連結する軸と、圧縮機構の内部に設けられ、圧縮機構
の電動機側の軸受から流出する潤滑油を圧縮機構の周囲
にある潤滑Ｍｕの貯溜部に導く流路とｌより成るもので
ある。
作　　用 本発明は上記した構成によって、圧縮機構の電動機側の
軸受より流出する潤滑油を、圧縮機構の内部に設けられ
た流路を通し、ロータの回転及び圧縮機構から吐出され
たガス冷媒に影響されることなく、圧縮機構の周囲にあ
る潤滑油の貯溜部に戻す。
その結果、軸受の出口において霧化される潤滑油は減少
し、圧縮機外へ吐出される潤滑油は減るため、高速運転
においても圧縮機内部に潤滑油は十分確保されることと
なる。

転においては、油ポンプの揚油量が圧縮機回転数の２乗
に比例して増加するが、流路２４を複数設けることによ

止できる。九たは、ロータ１６と上軸受２０との隙間を
十分小さくし、通路抵抗を増大することによってもオー
バフローを防止できる。すなわち、高速運転においても
、軸受２０から流出する潤滑油の霧化を防止できること
となる。その結果、圧縮機外へ吐出される潤滑油は減少
