Which of the statements is true concerning the illustrated hydraulic circuit when the directional control valve is centered? GS-0105 |
A) Oil pressure to both sides of the actuator will be equal as the pump discharge flow is directed across the relief valve. |
B) A pressure differential will exist between the two ends of the actuator, with pump discharge lower than normal due to flow across the unloading valve. |
C) The oil pressure will equalize at both ends of the actuator and the pump will discharge through the reducing valve to the sump. |
D) The load on the actuator may cause a difference in pressure to exist between the rod and cap end, and oil discharging to the sump across the relief valve with the pump operating. |
