Abstract

PURPOSE: To make an improvement of durability for high speed rotary operation, by providing a ruggedness axially in the seal ring.
CONSTITUTION: A seal ring 12 is formed into a shape that meets the shape of a backup ring 17, and a protruding part 12b is provided toward the side of a high pressure fluid chamber A from a flat part 12a engaged to a flat part 17a of the backup ring 17. This protruding part 12b makes an engagement to a protruding part 17b of the backup ring 17. Accordingly, the flat part 12a of the seal ring 12, familiarized with the flat part 17a of recessed part of the bakc up ring 17, is situated in the left side from the protruding part 17b, that is, in the low pressure side, and a contacting part 12c to a rotary shaft 10 comes to be in the low pressure side from the protruding part 12b of the seal ring 12, and though a lubricating fluid, sticking to the rotary shaft, is almost wiped by a sloped part 12d that varies from recessed part to protruding part, a necessary oil film is left with unlubricated part of the protruding part 12b lubricated.
