Abstract

1367546 Seals S KALLER 28 Sept 1972 [1 Oct 1971 28 Aug 1972] 44764/72 Heading F2B A sealing device for preventing leakage of high-pressure gas between relatively rotatable or axially movable elements comprises first and second seal rings 23, 22, a space 24 between the rings containing a non-gasous medium (e.g. oil or grease), the first ring being axially displaceable under the action of the gas and being arranged to impart to the medium a pressure higher than that of the gas. In the pneumatic spring shown, the axially-movable seal ring 23 is carried by an annular piston 25 and sleeve 26 and the oil in the space 24 is pressurized to a pressure greater than that of the gas in the cylinder 15 by an amount corresponding to the cross-sectional area of the sleeve 26. In another pneumatic spring, Fig. 1 (not shown), the oil in the space between the seal rings (7, 8) is pressurized by both the pressure of the gas and a compression spring (11) acting on the axiallymovable seal ring (7). The oil serves as a seal and lubricant and is replenished through a nipple (10).
