What component of the power steering system is powered by a belt and connected to the engine?

The rotary vane pump is a key component of the power steering system that is powered by a belt and connected directly to the engine. This pump is responsible for generating the hydraulic pressure necessary to assist in steering the vehicle. By drawing hydraulic fluid from the reservoir and pushing it through the steering gear, the pump helps make steering easier and more responsive, allowing for better handling of the vehicle.

The power cylinder, hydraulic fluid reservoir, and steering gear have different roles within the power steering system. The power cylinder utilizes the hydraulic pressure generated by the pump to assist in steering, and the hydraulic fluid reservoir stores the fluid necessary for the system's operation. The steering gear is the mechanism that translates the driver's input via the steering wheel into motion but does not generate hydraulic pressure itself.

Thus, identifying the rotary vane pump as the component connected to the engine emphasizes its crucial role in power steering functionality.
