9. HYDRAULIC OIL TANK 9. HYDRAULIC OIL TANK STRUCTURE STRUCTURE The oil from the hydraulic tank is sent from the pump through main control valve to the cylinders. In the return circuit, the oil from various parts merges. A part of oil is cooled in the oil cooler, passes through the hydraulic filter and returns to the hydraulic tank (1). If the hydraulic return oil filter becomes clogged, return filter bypass valve (6) acts to allow the oil to return directly to the hydraulic tank (1). This prevents damage to the hydraulic filter (5). The bypass valve (6) is also actuated when negative pressure is generated in the circuit.
