Abstract

1,248,323. Rotary shaft seal. TRIST MOULDINGS & SEALS Ltd. 1 Sept., 1970 [14 Nov., 1969], No. 55920/69. Heading F2B. In a rotary shaft seal comprising a first sealing ring 4 mounted on the shaft 1 for rotation therewith and a second sealing ring 8 on a non- rotatable sleeve 8 surrounding the shaft and slidable under spring pressure in the shaft housing 3 to urge the ring 8 against a frustoconical surface 25 on the ring 4, both sealing rings 4, 8 are within the housing 3 and the sleeve 10 is sealed to the housing at its outer end. A flange 11 forming the outer end of the housing is sealed to the sleeve by a rubber O- ring 16.
