See fig.8-5.With the forks upraised,high pressure oil led from the control

valve flows

into the chamber (A) and shifts the sleev

e (2) to the left.This opens the opening (G) to allow

the high pressure oil to flow along the two routes(A—B—G—D—E and A—B—C—D) and

both flows of oil lead to the lift cylinders.In this case,the flows of oil is not regulated.When

the forks begin to lower,oil discharged from the lift cylinders enters the chamber (E) and

shifts the sleeve until it contacts the nipple.This closes the opening (G) so that oil flows

through (E),(D),(H),(C),(B) and (A) to the tank.If the amount of oil discharged from the lift

cylinders is rapidly increased,the pressure in the chamber (F) rises

and moves the piston

(5) to the right in spite of the spring force,narrowing the opening (H).So the flow of oil from

the chamber (D) to the chamber (C)

is decreased so that the descending speed of the forks

is controlled.
