Abstract
1289937 Seals CROSS MFG CO (1938) Ltd 29 April 1971 12224/71 Heading F2B A cylindrical member 12, e.g. a piston, is sealed where it extends through a part-spherical recess 14 in a part 11, e.g. a cylinder, by spring sealing rings 15, 16 of substantially rectangular cross-section in side-by-side contiguity, the rings being alternately radially inwardly and radially outwardly springing to engage the surface 13 of the member 12 and the recess 11 respectively. The outer peripheries of the rings 15 may be ground spherically to match the concavity of the recess 14. The member 12 and part 11 may be relatively rotatable or static.
