Which characteristic is true for semi-integral power steering gears?

Semi-integral power steering gears utilize a control valve as a crucial component of their operation. This type of power steering system allows for improved steering assist compared to manual steering, where the driver must exert significantly more effort. The control valve regulates the flow of hydraulic fluid, which assists in reducing the amount of force needed to turn the steering wheel.

The design of semi-integral gear systems enables a combination of mechanical and hydraulic assistance, enhancing maneuverability, especially at lower speeds. This functional aspect allows drivers to enjoy easier handling and responsiveness when steering without requiring excessive physical force.

In contrast, systems that need more effort to steer would indicate a mechanical steering configuration, while self-contained systems generally refer to completely integrated setups with no external influence. Thus, the presence of a control valve is a defining trait of semi-integral power steering gears, contributing to their operational efficiency and user-friendliness.
