Claims (1)
流体の流入を封止する限定接触型シールとリツプ
シールとの組み合わせからなる軸封装置において
、前記限定接触型シールを外部流体側に配置し、
該限定接触型シールを通して浸入する流体に前記
回転軸部の回転作用による遠心力で外部流体圧よ
りも高い動圧を付加して前記流体を外部に放出可
能にしたことを特徴とする軸封装置。 In a shaft sealing device consisting of a combination of a limited contact type seal and a lip seal that seals the periphery of a rotating shaft of a machine body to prevent inflow of fluid from the outside, the limited contact type seal is disposed on the external fluid side. ,
A shaft sealing device characterized in that a dynamic pressure higher than external fluid pressure is applied to the fluid entering through the limited contact type seal by centrifugal force due to the rotational action of the rotating shaft portion, thereby making it possible to release the fluid to the outside. .
