Question 179General Subjects - Assistant Engineer

The correct answer is A) Accumulator. An accumulator is a component in a hydraulic system that stores pressurized hydraulic fluid, which can provide an instantaneous source of hydraulic force when the pump is temporarily shut down. This allows the system to continue functioning without interruption, even when the pump is not actively running. The other options, such as a modulator, pressure compensator valve, or sump actuator, do not provide this instantaneous hydraulic force when the pump is shut down, which is the key function needed to answer this question.
