Abstract

PURPOSE: To effectively cool the inside cylindrical surface of a seal ring, by providing the cylindrical surface with an annular recess and a plurality of oblique recesses which communicate with the annular recess.
CONSTITUTION: The inside sealing surface 7 of the lip 6 of the seal ring 4 is fluid- tightly fitted on the peripheral surface of a shaft 3. The annular recess 9 is provided on the sealing surface 7. The annular recess 9 communicates with one end of the sealing surface 7 through the oblique recesses 11, 12. When a shaft 3 rotates, a fluid is caused by the screw pumping action of the oblique recesses 11, 12 to flow into the annular recess 9 from the end of the sealing surface at one of the oblique recesses and flow out from the other oblique recess. The sealing surface 7 is thus cooled by the fluid.
