HYDRAULIC RESERVOIR Russian patent published in 2000 - IPC

FIELD: hydraulic reservoirs in hydraulic drives. SUBSTANCE: hydraulic reservoir ensuring deaeration of working fluid has body with return and intake cavities of working fluid. Attached to bottom between cavities is partition of separate sections made for change of height. Float is attached to upper part of partition in intake cavity. Partition sections are of the same height and connected with one another to limit motion of one relative to another. In folded state, sections are located on adjacent to another and in extended state, sections are located stepwise. Sections may be cylindrical or flat. Hydraulic reservoir ensures deaeration of working fluid. EFFECT: increased service life of partition and excluded mixing of liquid in cavities. 9 cl, 5 dwg
