The power steering oil pump assembly is primarily composed of the reservoir tank (1), power steering oil pump (2), power steering motor (3), and power steering control module (4).

RESERVOIR TANK
Fluid is filled from the reservoir tank.
POWER STEERING OIL PUMP
The power steering oil pump is driven by the power steering motor and generates hydraulic oil pressure in the system.
POWER STEERING MOTOR
The power steering motor is controlled by the power steering control module and drives the power steering oil pump.
POWER STEERING CONTROL MODULE
By receiving steering angle sensor signal and vehicle speed signal, the power steering control module calculates hydraulic pressure of the hydraulic pump electric power steering system according to the driving conditions. The power steering control module controls the power steering motor.
