7.2.3.2 Power steering pump assembly work principle

NL07-1007b

The power steering pump assembly is a vane-type power steering pump, and its operating principle is as shown in
figure

Rotating engine torque is transmitted to the power steering pump assembly belt pulley through the transmission
belt and drives the power steering pump assembly shaft and the rotor to rotate， blades installed on the rotor are
hurled out by the centrifugal force resulted in the revolution and revolves being attached closely and tightly to the
internal wall of the pump ring (pump rear shell body) to absorb the steering fluid in the oil pan into the pump
cavity and compress the steering fluid into the steering gear through the flow control valve for the purpose of
providing hydraulic driving force to the steering gear.

The flow control valve regulates the flow of the oil flowed into the steering gear according to the oil pressure in
the system to adjust the oil pressure in the system. Prevent the hydraulic pressure of the system too high.
