Poppet(C) is securely seated because the cylinder port pressure is normally higher than the
tank pressure and d

When the cylinder port pressure drops(Closer to negative pressure) until the cylinder port
pressure is lower than the tank pressure, poppet(C) opens receiving the tank pressure for
the difference in area between d

and d

; oil flows from the low pressure passage(Tank
passage) to the cylinder port in order to prevent cavitation.
