Abstract
PURPOSE: To prevent a sealing member from causing movement and deformation by a method wherein a high-pressure introducing hole is provided at a prescribed part of the sealing member and a high pressure is introduced into the sealing member which is placed on the side of a low-pressure area.
CONSTITUTION: The high-pressure introducing hole 30 is provided at the prescribed part of the sealing member S, and a high-pressure area H is communicated with the low-pressure are L through that part which is fitted into a groove 24 of a mounting flange 16, i.e. that part which seals the outside of the low-pressure are L. Accordingly, since a high pressure is applied also to each part of the sealing member S partitioning an intermediate-pressure area and the low pressure area L, the entirety of the sealing member is balanced with the high pressure and the member can be prevented from causing movement and deformation.
