型流体供給装置。 Forming an annular pressure space communicating with an external fluid supply source on the inner periphery of the case member into which the rotating shaft is inserted,
This pressure space includes a pair of cylinders that are pushed toward opposite sides in the axial direction by a spring and have sealing surfaces formed on the inner circumferential surface that slides against the rotating shaft and the end surfaces that contact the end surfaces of the case member on both sides of the pressure space. A fluid supply device via an internal rotary shaft, characterized in that a face seal is inserted therein, and a fluid supply line is formed in the rotary shaft, one end of which opens facing the gap between the two cylindrical face seals in the pressure space.
