Abstract
A joint includes a housing and a refrigerant tube connected to a refrigerant source and communicated with a target part in a rotating machine. A rotating member is loosely fitted inside with the refrigerant tube and fixed to a rotary part of the rotating machine. A relatively rotating member has a fixed-side member and rotating-side member. The fixed-side member is connected to the refrigerant tube via a refrigerant tube extension section. The rotating-side member is connected to the rotating member via a rotating member extension section. A refrigerant zone is formed by spaces defined between the refrigerant tube and the rotating member, and between the refrigerant tube and rotating member extension sections. A sealing member is installed between the fixed-side and rotating-side members. A vacuum chamber and pressure chamber are defined within the housing.
