The power steering pump, a part of your vehicle's power steering system, is the component that compresses the power steering fluid. It is basically a rotary vane pump that is powered by the engine via a belt and pulley. The construction of the pump includes a set of retractable vanes and an oval chamber.
How a Power Steering Pump works?
The power steering pump is used to put additional force onto the steering system when you turn the wheel. The pressure it provides comes from a rotary vane pump which is powered by the car’s engine. Inside this pump are retractable vanes that will spin inside an oval chamber and take power steering fluid from the lines at low pressure and distribute it at high pressure into the steering rack. As the pump is powered by the engine the speed in which the the pump flows is relative to the speed of the engine , meaning at high engine speeds the steering will operate quicker than an engine running at a lower speed. The pump has a pressure relief valve which will ensure the pressure isn’t too high , which is extremely effective on engines that are running at high speeds.
Vane Power Steering Pump
Vane pumps are the most common type of power steering pump used. In this type of pump the rotor is housed in an oval- or elliptical-shaped housing where it turns. Vanes fitted to the outside diameter of the rotor sit against the housing walls as the rotor turns. When power steering fluid enters into the vane pump housing it is trapped between the vanes, the housing wall and the rotor. A subsequent pressure increase causes the fluid to be pumped out of the housing and then through the outlet chambers.
