    • The mechanical seal (3) includes: a rotary side sliding ring (32) which is supported by the large diameter side outer circumferential face (23) of the annular step section (21) of the rotary shaft (2) via the rotary side O-ring (37) and press-fitted into the annular step section (21) by gas pressure in the device; and an unturnable stationary side sliding ring (31) which is fixed onto the seal housing (1) side via the stationary side O-ring (33) being capable of moving in the axial direction and being able to come into close contact with the sliding protrusion (323) of the rotary side sliding ring (32) due to the spring (36) so that the airtightly sealed sliding face S is formed. The rotary side sliding ring (32) is made of self-lubrication sliding material, and the stationary side sliding ring (31) is made of sliding material, the Young's modulus of which is higher than that of the self-lubrication sliding material. A deforming force given to the rotary side sliding ring (32) in the leaning direction caused by differential pressure between the high gas pressure and the atmospheric pressure outside the device is canceled by a deforming force caused by a component in the axial direction of the differential pressure acting on the annular step section (21) of the rotary shaft (2) in the pressing direction.
    • 机械密封件(3)包括:旋转侧滑动环(32),其经由旋转侧O的旋转轴(2)的环状台阶部(21)的大直径侧外周面(23)支撑 (37),并通过装置中的气体压力压入环形台阶部分(21); 以及经由固定侧O形环(33)固定在密封壳体(1)侧上的能够沿轴向移动并能够与滑动件紧密接触的不可转动的固定侧滑动环(31) 由于弹簧(36)使旋转侧滑动环(32)的突起(323)形成为气密密封的滑动面S。 旋转侧滑环(32)由自润滑滑动材料制成,固定侧滑环(31)由滑动材料制成,杨氏模量高于自润滑滑动材料。 由装置外部的高气体压力和大气压之间的压差引起的向倾斜方向施加的旋转侧滑环(32)的变形力由于差速器的轴向方向的分量引起的变形力而被抵消 作用在旋转轴(2)的环状台阶部(21)上的加压方向的压力。
