(1) Return filter (2) Hydraulic tank (3) Air breather (4) Element (5) Return chamber (6) Relief valve (7) Pipe (8) Port (9) Suction filter (10) Suction line (11) Tank chamberReturn filter (1) is mounted inside hydraulic tank (2) .The hydraulic tank contains return filter (1). The return filter consists of relief valve (6), return chamber (5), and element (4). Return oil from the bypass check valve flows to hydraulic tank (2) at port (8). The return oil flows from port (8) to pipe (7) and into return filter (1). The return oil flow from pipe (7) flows into return chamber (5). Return oil flows from return chamber (5), through element (4), and then to tank chamber (11) .Relief valve (6) allows the return oil to bypass the return filter when element (4) becomes plugged. The oil passes through suction filter (9) and the oil is delivered to the pumps through suction line (10) .Air breather (3) is located on the upper surface of the hydraulic tank. The air breather prevents an increase or a decrease of 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.
