Question 240Motor Plants - Assistant Engineer

The correct answer is C) indicate the quantity of oil flow to the cylinder. The component labeled as part No.20 in the illustration MO-0050 is likely an oil flow meter or indicator. Its primary function is to measure and display the amount of lubricating oil being supplied to the cylinder, allowing the operator to monitor and adjust the oil flow as needed. This is an important component for ensuring proper lubrication and preventing excessive or insufficient oil supply to the cylinder. The other answer choices are incorrect because they do not accurately describe the primary function of this component. Option A refers to metering the oil flow, which is a different function from indicating the flow. Option B is about adjusting the timing of the oil supply, which is not the main purpose of this particular component. Option D is about preventing backflow, which is not the primary function either.
