請求項(1)記載の回転式流体装置のシール構造。[Claims for Utility Model Registration] (1) A rotary fluid device comprising a rotating body 8 that rotates with its end face closely facing the fixed member 22, and fluid pressure is changed by the rotation of the rotating body 8. , a circumferential sealing groove 32 is formed in one of the opposing end surfaces of the fixed member 22 and the rotating body 8;
A tip seal 31 is provided in the seal groove 32 to seal between the fixed member 22 and the rotating body 8,
The tip seal 31 is formed by a band-shaped sealing material 33 spirally wound a plurality of times to overlap each other in the radial direction, and as it is wound in the spiral direction, it is displaced in the central axis direction, and is displaced in a predetermined central axis direction. A seal for a rotary fluid device, characterized in that both end surfaces of the tip seal 31 in the central axis direction are pressed against the fixed member 22 and the rotating body 8 in a ring shape. structure. (2) The tip seal 31 is configured such that the sealing material 33 is displaceable in the circumferential direction, and is configured to be drawn in and rewound by the fluid pressure difference between the inner and outer circumferential sides of the tip seal 31. A seal structure for a rotary fluid device according to claim (1).
