Abstract

1395107 Hydraulic accumulators MILTON ROY CO 29 Aug 1973 40642/73 Heading F1D In a hydraulic accumulator in which pressure pulses in a conduit 82 are damped by a spring- loaded bellows 56 in a chamber 40, the loading on the bellows can be adjusted by rotating a screw 68 with a handle 70. An annular member 64, on a shaft 62 attached to the end 58 of the bellows by a screw 60, co-operates with limit-stops 38, 54. Conduit 84 passes fluid to a reservoir. As described the accumulator is used in a liquid chromatographic system, Fig. 1 (not shown).
