Abstract
1,133,934. Seals. GUTEHOFFNUNGSHUTTE STERKRADE A.G. 28 Feb., 1966 [27 Feb., 1965], No. 8788/66. Heading F2B. A seal ring 10 is arranged to span a step in, for example, a compressor shaft and comprises an annular portion 10<SP>1</SP> spaced from the step and having an inner diameter less than that of the larger diameter portion d 2 of the shaft, the ring being loaded axially and having over its whole axial dimension a mean inner diameter d 3 approximately the same as the larger diameter portion of the shaft. The diameter d 3 also corresponds to the mean diameter at which the portion 10<SP>1</SP> abuts a casing 11. The ring, which may be non-metallic, is secured against rotation within the housing by a pin 13 and is supplied with sealing fluid which is directed through radial bores in both the casing and ring to an annulus 8 provided in the bearing surface which surrounds the larger diameter portion of the shaft.
