The power steering pump is a vane-type pump which provides hydraulic pressure for the system. The power steering system consists of the following components:
| • | The driveshaft |
| • | The pump housing |
| • | The pump ring |
| • | The pressure plate |
| • | The thrust plate |
| • | The flow control valve |
| • | The rotor |
| • | The vanes |
The opening at the rear of the pump housing contains the following components:
| • | The pump ring |
| • | The pressure plate |
| • | The thrust plate |
| • | The rotor |
| • | The vanes |
| • | The end plate |
The small opening on the side of the housing contains the following components:
| • | The pressure line fitting |
| • | The flow control valve |
| • | The spring |
The flow control orifice is a component of the pressure line fitting. A pressure relief valve inside the flow control valve limits the pump pressure.
