Dynamic pressure seal device and rotary joint device using the same |
摘要 |
Disclosed are a dynamic pressure seal device and a rotary joint device using the same which are applicable to a rotary body to be rotated at high speed and which are capable of effecting delivery of a target fluid between a rotary side member and a stationary side member without involving any leakage for a long period of time even when used for delivery of a high pressure fluid. The dynamic pressure seal device includes: a stationary side member mounted to a stationary portion and a rotary side member mounted to a rotary body, wherein the stationary side member and the rotary side member are opposed to each other through the intermediation of a predetermined bearing gap, a lubricant fluid being introduced into the gap to form a dynamic pressure bearing, the gap between the stationary portion and the rotary body being hermetically sealed by this dynamic pressure bearing.
