Abstract
1290087 End-face seals LEYLAND GAS TURBINES Ltd 24 June 1971 [15 Aug 1970] 39461/70 Heading F2B [Also in Division F4] A rotary thermal regenerator comprising a rotary disc-type matrix 2 located within a gas turbine engine casing 1 includes a flexibly mounted sealing element 3 of annular form which makes rubbing contact with a sealing surface of the matrix. As shown the sealing element, which is made of nickel oxide, has a wedge-like cross-sectional shape which tapers from maximum thickness adjacent the highpressure low-temperature side (i.e. zone 4) to minimum thickness at the low pressure high temperature side (i.e. zone 5). The element 3 has a small flat 6 at its maximum thickness and is mounted on a support ring 7 of ferritic steel which is fixed to one end of an annular flexible sheet metal member 8; the other end of the member 8 is firmly attached to the engine casing by means of an intervening annular plate 9 which is bolted at 10 to the casing.
