What is a Power Steering Pump?

Power steering is a key component of any vehicle, as it lets you quickly and easily control your truck on the road. If your power steering pump isn't working properly, your vehicle won't be able to turn as smoothly and may be in danger of causing an accident or other damage.

Power Steering Pump Definition

The Power Steering Pump is a vital component that allows you to turn the wheels of your car without much effort. It is a hydraulic system that transmits the power from the steering fluid to the wheel. When you turn the steering wheel, a rotary control valve sends pressure to a piston that helps you turn the wheels in either direction. The system is also able to detect speed and slow down the input from the steering wheel to reduce the sensitivity of the system at high speeds for safety.

Power Steering Pump Function

The power steering pump is the heart of the hydraulic system and converts rotational energy supplied by the engine from hydraulic fluid to power the steering gear. It contains a set of retractable vanes that spin inside an oval chamber and pull hydraulic fluid from the inlet line at low pressure and force it into the outlet at high pressure.
In this way, it circulates the hydraulic fluid to the steering gear, and it also uses a return hose to send the remaining fluid back to the pump for use again. This process continues continuously, reducing the amount of time the driver must manually turn the steering wheel.
A power steering pump also has an orifice that restricts its output flow to the steering gear at high engine speeds, allowing it to maintain constant pressure. In addition, a pressure relief valve prevents the build-up of dangerously high pressure at the end of a pump's stroke.
 

Application of Power Steering Pump

The power steering pump helps you turn your wheels. The fluid travels through a hose to the steering gear and another return hose sends it back to the pump. This process happens continuously while the engine is running, reducing the effort needed to turn the steering wheel.
Today, most vehicles use hydraulic or mechanical power steering. Depending on the make and model of your car, the power steering pump may be located near the engine or directly beneath the steering column. It can also be mounted elsewhere with a feed tube connected to the pump. A rotary valve senses the force you exert on the steering wheel and sends pressure to a piston based on the direction you want to turn. The piston then moves, causing your wheels to turn left or right.
