Abstract

1,164,804. Sealing rings. DUNLOP CO. Ltd. 22 Dec., 1966 [31 Dec., 1965], No. 55335/65. Heading F2B. A metal sealing ring 7 for the piston-rod 4 of a fluid pressure operated ram 1 comprises a disc 8 having integral cylindrical lip portions extending from its inner and outer edges, the outer lip portion 9 and the inner lip portion 10 being flared outwardly and inwardly respectively at a small angle to the ring axis. The rod 4 is slidably supported in bushes 5 in housings 6 and the ring 7, which acts in a primary sealing ring and sealingly engages the rod 4 and the ram cylinder 2, is located axially between annular rib 11 on the housing 6 and a spacer 12 hving two ribs 13 extending into recesses 14. Further sealing rings 15 which are of similar shape to the sealing ring 7 and act as secondary sealing rings are located in the recesses 14. Any leakage past the sealing ring 7 is returned to drain through port 20 and pipe 21. An L-section scraper ring 22 is secured to the outer bearing housing 6 by a circlip 24.
