7.2 Flow regulator
The flow regulator is located between the control valve and the high pressure
ports of the two lift cylinders, near the left lift cylinder. The structure of the flow
regulator valve is shown in Fig7.2.
When the lift spool valve is placed in the “lift” position, the oil from the control
valve flows through the oil chambers A and B, C, oil holes H, G, D, E, and the chamber
I to the lift cylinder without any regulation. When the control valve is placed in the
“down” position, the oil flows through chamber I, oil holes E, D, G, H, and chambers C,
B, A to the valve. Then there is pressure difference between chamber A and C. Turn
on the ball valve (4), a pressure difference overcomes the force of the spring (9) and
moves the valve core (5) right, thus the oil flow being decreased by narrowing of the
hole G and H, and reduces the oil flow passing through the throttle plate.
The flow regulator valve serving both as a flow regulating valve while forks are
being lowering and a safety device if rubber hoses between the control valve and lift
cylinders are damaged due to any reason.
