DESCRIPTION & OPERATION
RACK & PINION ASSEMBLY
Pump pressurizes fluid and sends it through the pump's flow control valve to the pinion and valve
on the rack and pinion assembly. See Fig. 1 . Pinion and valve direct fluid to either side of the
piston and rack, depending on turning direction of steering wheel. Piston and rack converts
hydraulic pressure into linear force, reducing turning effort.
POWER STEERING PUMP
Two types of power steering pumps are used, CB series or TC series. These pumps are constant
displacement vane-type pumps. See Fig. 6 and Fig. 7 . When pressure exceeds set limits, a flow
control pressure relief valve opens, allowing fluid to return to the inlet side of the pump. Some
pump applications have remote fluid reservoirs or reservoir attached to pump assembly, to enable
