Abstract

PURPOSE: To obtain shaft sealing for high-pressure fluid with high reliability by such a construction that an intermediate sealing ring is interposed between a rotary sealing ring and a stationary sealing ring, and a groove is excavated at the surface, working as a sealing face, of the intermediate sealing ring.
CONSTITUTION: On the outside surface of the shaft 3 piercing a casing 1, whose end a sealing ring 2 is fixed to, a sealing ring 4 is fitted with pobile possibility in the axial direction as well as an end ring 6 is fixed. A spring 7 is interposed between the sealing ring 4 and the end ring 6, and one of its ends 8 shall be projected and fitted in a groove 9 provided in the sealing ring 4 while the other end in a groove 11 provided in the end ring 6. An intermediate sealing ring 12 having a groove 17 on its periphery shall be interposed between these sealing rings 2, 4, and this groove 17 shall be in communication with the acting faces S1, S2 between the intermediate sealing ring 12 and the adjacent sealing ring 24. The fluid filling the groove 17 is delivered to the space between the sealing ring 12 and the casing 1 when they are rotating to increase the pressure strength of the fluid film in this part.
