に記載の両圧用シール。[Claims for Utility Model Registration] (1) Two cylindrical members that move relative to each other with a slight gap between them. ,1
In a seal that prevents leakage of fluid pressure from both directions, an arc-shaped protrusion is provided in the center of the moving side, and the protrusion is connected to the ends of both sides that are closer to the fixed part than the tip of the protrusion. A protruding part formed by an arc or an edge is provided at the center of the moving part consisting of a tapered surface and the fixed side surface that abuts the bottom surface of the annular groove, which is separated by valleys provided on both sides, and the circular arc or edge of the fixed side surface and the ends of both sides on the moving part side from the tip,
A double-pressure seal with a vertically symmetrical cross section, characterized by comprising a fixed part connected by a tapered surface having a smaller angle than the tapered surface on the moving side. (2) The tapered surfaces constituting the moving side surface are divided into a first tapered surface on the arc side that is in contact with the arc, and a second tapered surface on the side surface that is at a smaller angle to the moving surface than the first tapered surface on the arc side. The dual-pressure seal according to claim 1 of the registered utility model, characterized in that it is composed of a face and a face.
