The power steering pump is an essential component of a car’s hydraulic or electric power steering system. It plays a crucial role in ensuring that the driver can steer the car with minimal effort. Let’s take a closer look at the function of a power steering pump.

A. What Does a Power Steering Pump Do?

A power steering pump helps in generating hydraulic pressure, which assists in turning the wheels of a car. It does this by pumping power steering fluid into the steering mechanism, which then applies pressure to the steering rack or gearboThis pressure, in turn, helps to turn the wheels of the car with less effort from the driver.

B. How Does a Power Steering Pump Work?

The power steering pump works by utilizing a belt-driven pulley to turn a rotor, which is responsible for pumping the fluid that powers the system. The pulley is driven by the car’s engine, and the rotor is housed inside the power steering pump. As the rotor turns, it pushes the fluid from the pump into the steering mechanism, which then assists in turning the wheels.

C. Components of a Power Steering Pump

A power steering pump consists of several key components, including the pump housing, the rotor, vanes or impellers, the pressure relief valve, and the power steering fluid reservoir. The pump housing is where the rotor is housed, while the vanes or impellers help in creating the necessary pressure. Meanwhile, the pressure relief valve helps to regulate the pressure within the system, preventing any damage from occurring. Finally, the power steering fluid reservoir stores the fluid that powers the system.

Types of Power Steering Pumps

As mentioned earlier, power steering pumps can be hydraulic or electric. However, there is also a third type of power steering pump known as the belt-driven power steering pump. Let’s take a closer look at each type:

A. Hydraulic Power Steering Pump

Hydraulic power steering pumps were the first type of power steering pump introduced in cars. They operate by using hydraulic pressure to assist the driver in turning the wheels. This type of pump is powered by the engine and uses a hydraulic fluid that is pressurized by the pump to help move the wheels. Hydraulic pumps are known for their durability and longevity, making them a popular choice among car manufacturers.

B. Electric Power Steering Pump

Electric power steering pumps are a newer technology and operate by using an electric motor to provide the necessary assistance to the driver. Unlike hydraulic pumps, electric pumps do not require any hydraulic fluid, making them a more environmentally friendly option. Additionally, electric pumps are more efficient and offer better fuel economy, making them an attractive choice for car manufacturers.

C. Belt Driven Power Steering Pump

Belt-driven power steering pumps are typically found in older cars and operate using a belt that is connected to the engine. The belt drives a pulley that, in turn, powers the power steering pump. While this type of pump is not as efficient as hydraulic or electric pumps, it is still a reliable option and can provide adequate assistance to the driver. However, belt-driven power steering pumps are becoming less common as newer and more efficient technologies are developed.

Symptoms of a Faulty Power Steering Pump
