Hydraulically, servo-operated, automatic, change over valves, utilized in a two ram hydraulic steering gear, serve to _______________.
AI Explanation
The correct answer is C) prevent either main pump from being hydraulically motored when idle by cross pressure flow.
Servo-operated, automatic, change over valves in a two-ram hydraulic steering gear system are designed to prevent the idle pump from being hydraulically motored by the active pump. This cross-pressure flow could potentially lead to damage or malfunction of the idle pump. By preventing this unwanted hydraulic motoring, the valves ensure the integrity and reliable operation of the overall steering system.
The other answer choices, while related to hydraulic system design, do not directly address the specific function of the change over valves in preventing hydraulic motoring of the idle pump.
