Claims

[Scope of utility model registration request]

In a rotary joint that connects fixed side piping and movable side piping or piping with different rotational speeds, the main body connected to one piping rotates the sleeve connected to the other piping via a transfer support mechanism such as a ball bearing. The fluid passage ends of both members are connected via a rotary shaft sealing mechanism such as a mechanical seal, and a pair of the rotary shaft sealing mechanisms is provided between the main body and the sleeve on the outer periphery of the rotary shaft sealing mechanism. A rotating shaft sealing mechanism is interposed and connected, and a cylindrical baffle sleeve extending from the main body is deeply inserted into a relatively deep cylindrical hole that is bored in the sleeve and communicates with the annular portions of both rotating shaft sealing mechanisms. The baffle sleeve is inserted to form a cylindrical regulating fluid passage inside and outside the baffle sleeve, and a pair of regulating fluid ports are opened in a part of the main body, communicating with both ends of the inner and outer regulating fluid passages, respectively. rotary joint.
