Hydraulic tank (1) Air breather (2) Element (3) Return chamber (4) Hydraulic tank (5) Return filter (6) Tank chamber (7) Suction line (8) Suction filter (9) Port (10) Passage (11) Relief valveThe return oil flows through bypass check valve and passage (10) to return chamber (3) and return filter (5). Also, the return oil from the oil cooler flows from port (9) to return chamber (3) .Return filter (5) consists of element (2) and relief valve (11). Three return filters are mounted on the rear surface of the hydraulic tank.The oil passes through element (2) of return filter (5) and flows into tank chamber (6). Thereafter, the oil passes through suction filter (8) and the oil is delivered to the pumps through suction line (7) .Air breather (1) is mounted on the upper surface of the hydraulic tank. The air breather maintains a certain air pressure in the hydraulic tank regardless of the following circumstances :
Change of air pressure in the hydraulic tank due to cylinder movement.
Change of air pressure in the hydraulic tank capacity due to a temperature change.
