In the power steering unit, the method used to direct a single source ot fluid pressure in either of two directions (for left or

right turns) involves the pinion gear transferring a

"message" oJ direction to the tluid in the 4-way valve

The pinion is mounted slightly off-center in a pair ot bearings, which are in turn mounted in a pinion holder cylinder that

rotates, centered in its own outer bearings. At the bottom ol the Pinion Holder is a pin, which fits in a slot in the 4-way

As the pinion is turned (to turn lett or right), because it is off-center. it also moves slightly along the rack. This movement

is transferred to the holder. The pin in the holder then moves the 4-way valve, to direct fluid pressure to either side of the

rack in th€ power cylinder.

The bsck edges ot the pinion holder (facing away lrom the rack) hit the stops cast into both sides of the gear housing to

avoid pushing the 4-way valve too far in either dirsction, The tront edge of the pinion holder cuts off assist at full lock as

described on the next page.
