通路を有することを特徴とする密封装置。 An annular groove provided inside the main body so as to seal the shaft surrounded by the main body and reciprocating with respect to the main body so that pressure does not leak from the high pressure side to the low pressure side of the main body,
In a sealing device including a sealing member disposed in an annular groove and fluid pressure guided from a high pressure side to press the sealing member, the sealing member has a slight gap in the annular groove shape inside the annular groove. a complementary o-ring and a packing disposed to abut the o-ring and the shaft and having an axial width approximately the same as the annular groove, the packings being circumferentially spaced apart near the high-pressure end. A sealing device characterized in that it has a plurality of radial passages.
