Abstract
1,140,435. Seals. SOC. D'ETUDES ET DE DEVELOPPEMENT DES INDUSTRIES MODERNES. 8 May, 1967 [12 May, 1966; 28 Nov., 1966], No. 21275/67. Heading F2B. A device for sealing a compressor shaft 3 and permitting a limited leakage comprises a sleeve 2 disposed around the shaft with slight play and sealed to a casing 1 as by an 0-ring 6, the sleeve or shaft being made of P.T.F.E. or graphite to prevent them from seizing during acceleration or deceleration of the shaft, while during normal running the sleeve serves for an aerodynamic or hydrodynamic bearing. The sleeve 2 may be sealed to the casing by a bellows or a diaphragm instead of an 0-ring. The clearance between the sleeve and shaft may be controlled by supplying fluid pressure to the outer or inner surface of the sleeve to distort it, Figs. 4, 5 and 7 (not shown). Two sleeves may be used in series when the pressure difference is great, fluid of an intermediate pressure being supplied between the two sleeves, Fig. 8 (not shown). The device may also be used for sealing liquid or steam.
