Fluid Flow Circuit (Part 2 Of 2)
STEERING IN THE STRAIGHT-AHEAD POSITION
With the steering in the straight-ahead position:
^
The valve restrictions are balanced.
^
Equal pressure is present on both sides of the piston.
TURNING THE STEERING WHEEL CLOCKWISE
When the steering is turned clockwise:
^
The rack and piston of the operating cylinder move to the right.
^
Pressurized fluid is supplied to the left piston chamber to provide power assistance.
^
The three control ports of the rotary distributor are moved in a clockwise direction so that the inlet ports (16) are opened further.
^
As this occurs, the inlet ports (15) close to prevent the fluid reaching axial grooves (17) in the control sleeve.
^
With the valve in the operating position pressurized fluid flows through the inlet ports (16) to the lower radial groove (12) in the control
sleeve.
^
From the control sleeve, pressurized fluid flows to the left piston chamber to provide hydraulic assistance for the piston movement.
^
The closed control slot (23) prevents fluid flowing back to the reservoir.
^
The oil is forced out of the right piston chamber through the upper radial groove (11) in the sleeve to the return slots (19) in the rotary
distributor.
^
Webs (22) on the rotary distributor prevent the fluid flowing directly to the return grooves (20), which are always open in the direction of the
control sleeve.
TURNING THE STEERING WHEEL COUNTER-CLOCKWISE
When the steering wheel is turned counter-clockwise:
^
The rack and piston of the operating cylinder move to the left.
^
Pressurized fluid is supplied to the right piston chamber to provide power assistance.
