Hydraulic Power Steering Pump with Genuine Part

Mechanical hydraulic power Steering System
The hydraulic steering system is the addition of a hydraulic assist system to the original mechanical steering system, which can provide some steering assistance, thereby reducing the operating intensity of the driver. It is generally composed of hydraulic pumps, oil pipes, pressure flow control valve bodies, V-shaped transmission belts, oil storage tanks, and other components. On its steering mechanism, there is a mechanical valve that can rotate with the steering column. When the steering wheel does not rotate, the pressure in the chambers on both sides of the piston is consistent and in a balanced state. When the steering wheel rotates, the mechanical valve connected to the steering column will correspondingly open or close. One side of the hydraulic cylinder will no longer pass through and directly return to the oil reservoir. The other side of the hydraulic cylinder will continue to inject oil. The pressure difference between both sides of the piston will be pushed under the action of hydraulic force, which will generate auxiliary force to push the steering rod, causing the wheels to turn, greatly reducing the force required for us to rotate the steering wheel.

How does a Power Steering Pump work?

Generally, vane pump is composed of a pump body with double arc curves in the inner chamber, a slotted rotor, vanes and other parts. Some are installed on the flywheel housing at the rear end of the engine, and are also driven by timing gears. When the engine is running, the booster pump rotor is driven to rotate, and the vanes move outward along the blade grooves under the action of centrifugal force, and are close to the inner wall of the pump body. During the rotation of the rotor, due to the continuous increase and decrease of the closed volume between the vanes , to realize the process of oil absorption and oil pressure. Every time the rotor rotates once, it completes oil absorption and oil pressure twice. There is also a safety valve in the pump body to limit the maximum pressure. When the external load of the steering system increases, causing the oil pressure to rise to a certain value, the safety valve opens to unload the load. A throttle valve and a flow control valve are also installed in the pump body to ensure that the displacement of the booster pump is basically stable.
