Abstract
1,168,199. Shaft seals. SEALOL Inc. 24 May, 1968 [3 June, 1967], No. 24954/68. Heading F2B. In a balanced seal, the axially-movable ring L of L-section surrounds an enlarged portion 14 of a shaft 10 and is supplied with pressure fluid on one side 18 and with a buffer fluid on the opposite side 30. As shown, pressure fluid is supplied to the side 18 through a clearance 12 between the shaft 10 and housing 11 and buffer fluid at a constant flow rate is supplied to the opposite side 30 whence it is discharged through a restricted outlet 32. In Fig. 3 (not shown), the end face (28) of the ring is sealed to the housing by two radially-spaced mechanical seals, the space between which defining a chamber for the circulation of the buffer fluid, preferably cooled for cooling the two mechanical seals. In Fig. 4 (not shown), the pressure fluid acting on the side (18) is assisted by a spring (59) and a baffle (53) is provided on the ring to reduce the impinging force of the buffer fluid.
