Abstract

1349510 Piston rings; shaft seals HEPWORTH & GRANDAGE Ltd 10 May 1971 [15 May 1970] 23773/70 Addition to 1099235 Headings F2B and F2T In a split spacer ring for a sealing ring 32 having integral independently operable circumferentially spaced leaf springs 14 for engaging the sealing ring and two axially spaced faces 22, the ends of the spacer ring are radially aligned by projections 24 on one end of at least one of the faces 22 engaging a recess 26 in the other end. The spacer ring is formed from spring steel strip and each spring 14 has a cross link 16 to engage two sealing rings 32. A projection 24 and corresponding recess 26 are provided on the free ends of each face 22 and the projections are engaged by a link 16a of a leaf spring 14a. The composite piston ring 30, Fig. 3, comprises two split sealing rings 32 located with the spacer ring in a groove 38 in a piston 39 and urged against the cylinder bore 40 by the springs 14. The spacer ring may be of rectangular crosssection as shown or of U-section. The invention may be applied to a shaft seal.
