Abstract

1275575 Hydraulic accumulators A ELMER 15 Oct 1969 [18 Oct 1968] 50692/69 Heading F1P The liquid contacting side of the floating piston 7 of a hydro-pneumatic accumulator has a nose 11 surrounded by a flat annular surface 12 which when the cylinder is nearly empty of liquid and the nose 7 projects into the dished base, abuts a stationary sealing ring 14 and traps residual liquid in a chamber 18, and so prevents leakage of gas past a scraper ring 10, a sealing ring 8 and a guide ring 9 carried by the piston 7. On admitting pressurized liquid through an opening 2 to the nose 7 a check valve 15 opens to admit the liquid to chamber 18 and assist in lifting piston 7. (For Figure see next page)
