Difficulty: Easy
Choose an option
-
AOne stroke
-
BTwo strokes
-
CThree strokes
-
DFour strokes
Answer
Correct Answer: Two strokes
Explanation
Concept/ApproachIn a single-acting cylinder, suction occurs during one piston stroke (e.g., downward), while compression and delivery occur during the opposite stroke (e.g., upward) as the discharge valve opens once cylinder pressure exceeds delivery pressure.
SequenceStroke 1: Suction.Stroke 2: Compression & Delivery.
Final AnswerTwo strokes
