特徴とするシヤツトダウンシール。 The sliding end of the sealing ring, which is slidably and airtightly supported on the housing side with an appropriate axial stroke against the sliding surface of the mating ring airtightly mounted on the rotating shaft, Further, the seal ring is pressed and elastically biased toward the mating ring, and positive pressure is applied between the seal ring and the housing side member to cause the seal ring to resist the pressing elasticity. A shutdown seal comprising an annular pressure chamber formed by applying pressure in a direction away from a mating ring, and fluid pressure is applied to the annular pressure chamber when a rotation shaft is driven.
