The power steering pump is a vane-type design. The submerged pump has a housing and internal parts that are inside the reservoir and operate submerged in oil.
There are 2 bore openings at the rear of the pump housing. The larger opening contains the following components:
• | The cam ring |
• | The pressure plate |
• | The thrust plate |
• | The rotor |
• | The van assembly |
• | The end plate |
The smaller opening contains the following components
• | The pressure hose union |
• | The flow control valve |
• | The spring |
The flow control orifice is part of the pressure hose union. The pressure relief valve inside the flow control valve limits the pump pressure.
