Abstract

PURPOSE: To prevent a leak of high pressure fluid, by shaping each of the contacted end faces of a driven ring and sealing ring into a spherical surface and forming the spherically tight-sealed surface with the both end faces.
CONSTITUTION: Between a case 1 and rotary shaft 6, a sealing ring 5, mounted to a cover 2 through a buffer ring 2, and a driven ring 7, mounted to the rotary shaft 6 through a packing 8 and a spring 9, are arranged. Then each of contacted end faces of the sealing ring 5 and the driven ring 7 is shaped in a spherical surface in such a manner as to form the tightly sealed surface 10. In this way, even for the displacement of the driven ring 7 due to the improper mounting at the time of assembly and the load at the time of operation, the tight-sealed surface 10 can be maintained in a tightly sealing state to prevent a leak of high pressure fluid.
