What key component in the power steering system assists the driver with turning?

The power steering system is designed to make steering easier for the driver by amplifying the effort a person applies to the steering wheel. The pump plays a crucial role in this process. It is responsible for moving hydraulic fluid through the system, which creates the necessary hydraulic pressure that assists in turning the vehicle's wheels. This hydraulic assistance significantly reduces the physical effort required by the driver, especially when turning at low speeds or while parking.

The pump generates this pressure by drawing hydraulic fluid from the reservoir and directing it to the steering mechanism when the driver turns the wheel. This action provides a force that helps turn the steering gear, making maneuvering the vehicle more effortless and responsive. Therefore, understanding the function of the pump clarifies why it is considered a key component in the power steering system.
