Abstract
Description
3 駆動軸
4 圧縮機構部
7 上軸受
9 下軸受
9a ボス
11a 上圧縮室
11b 下圧縮室
15a 上吐出空間
15b 下吐出空間(吐出空間)
16b 下バルブカバー
19 オイル溜り
22 吐出ポート
24 オイル保持部
25 隔壁(区画領域)
26 締結面
図1は、本発明の実施の形態1における圧縮機の縦断面図である。
また、ボス9aの外径の中心軸9a1と内径の中心軸9a2とをずらしている。ボス9aの外径の中心軸9a1と内径の中心軸9a2とを一致させないことにより、下軸受9と下バルブカバー16bとの締結面26において、特に中心側の締結面26でのシール長を十分に確保したり、下軸受9の負荷の高い位置でのボス9aを厚くするなど、ボス9aの形状を自由に設計することが可能となり、高い信頼性を確保することが可能である。
なお、下軸受9と下バルブカバー16bとの締結面26、すなわちシール部26a〜26eにはシール材(図示せず)を設けることが好ましい。
