More Information
Summary:A rotary joint capable of lubricating a sealing surface of a mechanical seal forming a fluid passage through which a gas flows using a liquid even when the liquid flows through only one fluid passage is disclosed. A rotary joint includes a plurality of mechanical seals provided in an axial direction in an annular space between a case body and a shaft body to form a first intermediate flow passage that connects a first outer flow passage and a first inner flow passage of a first fluid passage through which a liquid flows to each other and form a second intermediate flow passage that connects a second outer flow passage and a second inner flow passage of a second fluid passage through which a gas flows to each other.
