Bosch Rexroth R978713171 Accum Bladder hydraulic accumulator, bladder-type, with a nominal capacity of 0.25 gallon, stores hydraulic energy and helps damp pressure transients in closed‑loop systems. The design uses a gas‑charged bladder to separate the hydraulic fluid from the gas, enabling quick response to pressure changes while minimizing fluid contamination. Typical uses include energy storage and surge damping in hydraulic circuits and volume compensation to maintain stable system pressure during varying load conditions.
