Abstract

　液体が密封された第１密封領域への気体漏れを防止すると共に気体が密封された第２密封領域への液体漏れを、より確実に防止することを可能とする。 　第１密封領域Ｏへの窒素ガス漏れを防止すると共に第２密封領域Ｇへの油漏れを防止する密封装置５０において、第１密封領域Ｏ側に設けられる第１シールリップ５１のリップ先端の形状と第２密封領域Ｇ側に設けられる第２シールリップ５２のリップ先端の形状が、第１シールリップ５１がピストン３２の表面に対して摺動した際に摺動部分に形成される油膜の厚みが、第２シールリップ５２がピストン３２の表面に対して摺動した際に摺動部分に形成される油膜の厚みよりも薄くなるように構成されていることを特徴とする。
